Gluons can be converted into quark-antiquark pair s giving raise to the sea quark. Quantum Chromodynamics (QCD) is the funda mental theory that describes the strong interaction\; however\, due to the complexity of the quark-gluon dynamics\, QCD does not allow us to get ana lytical results in the energy region of interest to Nuclear Physics at low 4-momentum transfer\, $Q^2$. Alternatively\, the internal dynamics of the quarks inside the nucleon can be described in terms of several phenomenol ogical functions (form factors) which depend on a single scalar variable: $Q^2$. \n\nThe form factors are related to the electric\, magnetic\, axial and axial-vector charge distributions in the nucleon. The study and deter mination of these nucleon form factors can provide constraints to the micr oscopic models that aim to describe the nucleonic structure from QCD. More over\, form factors are a main ingredient for the description of the lepto n-nucleus/nucleon cross sections.\n\nOne of the main objectives of our wor k is to improve the current knowledge on the structure of the nucleon thro ugh the study of the form factors. As tools\, we have analyzed elastic ele ctron-nucleon and quasielastic electron-nucleus scattering processes. Thes e reactions provide information on the electromagnetic (EM) and weak neutr al current (WNC) form factors. \n\nAlthough the EM interaction is dominant in electron-nucleon/nucleus scattering\, i.e.\, parity conserving process es\, the electron also feels the weak (neutral) interaction that does not conserve parity. Due to the strength of the weak interaction (several orde rs of magnitude lower than the electromagnetic one) to get information on the weak interaction is essential to analyze observables whose presence is due unequivocally to parity violating processes. Thus\, we have studied t he observable called parity violating asymmetry (${\\cal A}^{PV}$) defined as ${\\cal A}^{PV}=(\\sigma^+ - \\sigma^-)/(\\sigma^+ + \\sigma^-)$\, whe re $\\sigma^{+/-}$ represents the differential cross section (electron-pro ton or electron-nucleus) with positive/negative helicity of the incident e lectron.\n\nThe PV asymmetry linked to the elastic electron-proton scatter ing (PVep asymmetry)\, $p(\\vec{e}\,e')p$\, is particularly sensitive to t he electric and magnetic strange contributions. An statistical analysis of all PVep asymmetry data has also been presented. From this analysis we ha ve got the highest precision constraint for the vector strange form factor compatible with the experimental data up to date.\n\nWe have also present ed a general study of the PV asymmetry associated to quasielastic electron -nucleus scattering processes (PVQE asymmetry). From our analyses we concl ude that the PVQE asymmetry is an excellent observable to obtain nucleonic information on the axial-vector sector of the weak neutral current. Speci fically\, measurements of the PVQE asymmetry at backward scattering angles would provide information on the radiative corrections entering in the is ovector axial-vector sector.\n\nhttps://indico.ific.uv.es/event/2851/contr ibutions/4531/ LOCATION:Facultade de Química (USC) Aula Química Física URL:https://indico.ific.uv.es/event/2851/contributions/4531/ END:VEVENT BEGIN:VEVENT SUMMARY:Validación de la precipitación en modelos: protocolos y notas me todológicas DTSTART;VALUE=DATE-TIME:20170717T161500Z DTEND;VALUE=DATE-TIME:20170717T163000Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4528@indico.ific.uv.es DESCRIPTION:Speakers: Francisco J.

Siendo la precipitación un campo geofísico de alta variabilid ad espacial\, y dependiente de un modelado adecuado de la dinámica y la t ermodinámica\, una buena correspondencia con las observaciones es no solo una condición necesaria (aunque no suficiente) para establecer las capac idades del modelo\, sino también un buen indicador de calidad.

This property\, added to the low spin-orbit coupling makes o rganic radicals promising candidates for Molecular Spintronics provided th at the radical character is stable in solid state electronic devices.\n\nW e measure electron transport through individual PTM organic radicals. We s how that the radical centre and therefore the magnetism\, is preserved in a variety of individual neutral radicals in single-molecule solid state de vices\, ranging from monoradicals [1] to polyradicals [2\,3] (di- and tri- radicals). The magnetism\, in the shape of a Kondo anomaly\, is robust aga inst mechanical and electrical perturbations.\nIn polyradicals (see Figure 1)\, where several unpaired spins are coupled via exchange coupling in a single high-spin purely organic molecule\, we show that the local environm ent can induce a sign reversal of the exchange interaction\, from ferro to antiferro\, inducing a change in the magnetic ground state of the individ ual molecule [2]. In addition\, diradicals can be reversibly and controlla bly charged preserving the radical character. The controlled access to dif ferent redox states of the molecule\, allows to perform Inelastic Electron Tunnel Spectroscopy (IETS) of the spin spectra in both redox states and f orms the basis of a SWAP quantum gate[3].\n\n[1] R.

In fa ct\, the characteristic intermittency of renewable sources necessarily dem ands for its effective integration some combination of efficient and flexi ble backup plants\, large energy storage systems\, smart grids\, etc. and\ , consequently\, the costs of electricity could be notably increased.\nThi s article analyses the present situation of the power mix making use of th e latest data available from the Spanish distribution grid regulator (Red Eléctrica Española). The study is carried out in a two-tier analysis: Fi rstly we perform a descriptive analysis of the latest trends comparing the generation of the last years. Secondly\, based mainly on the European dir ections on the future limitations of CO2 emissions\, we make an analysis o f the deployment of the optimal mix of VRES that would minimize the both t he need of backup from conventional sources\, as well as surpluses. A redu ction in fossil fuel generation\, as recommended by the European Union (EU ) and several international treaties\, is also considered. As far as we kn ow\, this kind of studies\, based on linear programming for establishing t he optimal power generation mixes for VRES at a country level\, are unusua l and yet to come. However\, they can provide key figures to policymakers for the establishment of desirable investments for renewable energies in t he nearly future.\nEvidently\, the main difficulty of the above study is c aused by the large unpredictability of wind and solar resources and for th is reason we base our optimization technique on the hourly data series (87 60 hours in one year) provided by REE. It is also interesting to point out that in finding the optimal mix for VRES\, we have considered two compone nts for solar: photovoltaics (PV) and concentrating solar power (CSP). Pra ctically\, none of the European scenarios take into account these two sola r components since it is known that for latitudes higher than the one of S pain\, the conversion efficiency of CSP diminishes very rapidly. \nIn this work we have studied three possible scenarios. In the first one we suppos e the hypothetical case of the total demand being mostly supplied by varia ble renewable energies. In this case\, it is assumed that all the electric ity demand is covered by wind and solar energies (PV and CSP). To do so in the solution of the problem we apply the stringent condition that the res ulting mix should be optimal\, that is\, that the 8760 hourly periods in t he year of backup and surplus are simultaneously minimized. The solution o f the problem gives\, as expected that the increase in VRES needed is too large to be implemented before 2030. In addition the amounts of surplus an d backup are also unmanageable without an efficient storage and lack of de mand-side response technologies.\nIn the second case we suppose that the h ydraulic and nuclear generation are maintain ned at their present levels. Therefore\, the VRES should cover only the reduced demand\, that is\, the difference between the total demand minus the sum of the hydraulic and nuc lear components for each of the hours of the year. Under this situation\, the solution of the optimization problem yields that the present wind\, so lar-PV and solar-CSP generations would have to be increased by 97%\, 20%\, and 528%\, respectively. In this case\, we have also calculated the aggre gated yearly backup needed and the surplus obtaining 14.2 and 5.7 TWh\, re spectively. It is also evident that without storage the surplus electricit y would be lost.\nIn the third scenario we study the more realistic case t hat Spain will follow the targets assigned by the EU for the reduction of emissions in 2030 as well as the increase of the corresponding renewable e nergies. This implies a drastic reduction in the future coal-generated ele ctricity reaching 15.2 TWh by 2030 (about 30% of its present amount). We c all this case\, the European Union-2030 Scenario. After performing the cor responding operations for the optimization problem\, as in the previous ca se\, we find that the current wind\, PV and CSP generations would have to be augmented by 64%\, 27%\, and 332%\, respectively. In addition\, the yea rly backup and surplus have been drastically reduced to 2.9 and 3.3 TWh\, respectively. We would like to remark that it might appear surprising the large percentages resulting for CSP which can be explained by its low pres ent participation in the actual generation mix and above all by its possib ility of evening and overnight storing of energy during several hours afte r sunset.\nIt is important to remark that the needed backup will be mainly supplied by natural gas plants\, which are less contaminating and have a faster response than coal plants. Finally\, in this communication\, we als o discuss other strategies that will have to be implemented if we want to handle large amounts of VRES. These are storage\, demand-side management\, distributed generation\, and smart grids\, since they contribute to the i mprovement of the so-called flexibility of the systems for power generatio n. With respect to the management of the surplus\, evidently storage could in theory accumulate the corresponding energy for later use\, thus partia lly substituting the backup systems. However\, a massive use of storage st ill has to wait due to the high cost of batteries and the need of a practi cal seasonal storage (summer-to-winter in the case of solar) yet to be dev eloped.\nAcknowledgments\nThe authors would like to acknowledge the suppor t given by the Spanish Royal Physics Society (RSEF) and Red Eléctrica Esp añola (REE) for the realization of this work.

Dichos materiales porosos s e obtendrán reciclando los siguientes residuos agrícolas y forestales: c áscara de almendra\, cáscara de nuez\, carbón vegetal y fibras de kenaf .\nSe concluye que los mayores rendimientos energéticos a largo plazo (pa ra tiempos de reacción superiores a 112 días) se obtienen cuando se usa carbón vegetal como material alveolar\, con un incremento de la producci ón de metano\, respecto a la biometanización de la mezcla pura\, del 27\ ,82%.\n\nhttps://indico.ific.uv.es/event/2851/contributions/4510/ LOCATION:Facultad Química (USC) Aula Químca Orgánica URL:https://indico.ific.uv.es/event/2851/contributions/4510/ END:VEVENT BEGIN:VEVENT SUMMARY:ADVANCES IN MAGNETIC FORCE MICROSCOPY IMAGING: FROM PERMANENT MAGN ETS TO BACTERIA DTSTART;VALUE=DATE-TIME:20170717T140000Z DTEND;VALUE=DATE-TIME:20170717T141500Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4507@indico.ific.uv.es DESCRIPTION:Speakers: Miriam Jaafar (Instituto de Ciencia de Materiales de Madrid)\nDespite decades of advances in magnetic imaging\, obtaining dire ct\, quantitative information with high spatial resolution remains an outs tanding challenge. The imaging technique most widely used for local charac terization of magnetic nanostructures is the Magnetic Force Microscope (MF M)\, which is indeed a very active topic of investigation. Advantages of M FM include relatively high spatial resolution\, simplicity in operation as well as sample preparation\, and the capability to applied in situ magnet ic fields to study magnetization process [1\, 2]. Recently we have also de monstrate the possibility of operate in different environments including l iquid media that allow us to investigate biological samples [3]. \nIn the present work we try to approach some of the challenges of MFM\, spatial r esolution\, sensitivity and quantitative measurements\, by following diffe rent routes.\nOne route is the development of high-performance MFM probes with sub-10 nm (sub-25 nm) topographic (magnetic) lateral resolution by fo llowing different easy and quick low-cost approaches. This allows one to n ot only customize the tip stray field\, avoiding tip-induced changes in th e sample magnetization\, but also to optimize MFM imaging in vacuum (or li quid media) by choosing tips mounted on hard (or soft) cantilevers\, a tec hnology that is currently not available on the market [4]. In Figure 1 we show an example of the advantages of tune the mechanical properties of the cantilever. We compare the MFM images of a reference sample (a commercial high disk) acquired with a commercial MFM tip (Figure 1 a and b) and a cu stom-made probe (Figure 1 c and d) at ambient conditions and in liquid env ironment. It is well known that due to the viscosity of the liquid media there is a decrease in the quality factor of the cantilever and\, for that reason\, an increase of the noise in the MFM images. Using specific custo mized MFM probes we can enhance the signal in about a factor of 10 and imp rove significatively the quality of the images. Moreover\, with this custo mized MFM probes we can obtain MFM images of biological materials in physi ological conditions. In figure 2 we present the topography and the magneti c signal of magnetotactic bacteria Magnetospirillum gryphiswaldense [5] ac quired with custom made MFM tips. Furthermore\, the idea of explore new MF M probe architectures [6] allow us to focus some of the challenges of the technique as the lack of quantitative information. In that sense\, alterna tive advanced methods as measuring energy dissipation with MFM is of great interest not only for nanomechanics but also to understand important ener gy transformation and loss mechanisms that determine the efficiency of ene rgy of data storage device [7].\nAcknowledgments\nWe acknowledge the suppo rt from the Spanish Ministerio de Economia y Competitividad (MINECO) under projects no.

Ther apy with protons is\, by far\, the most largely charged particle technique used\, having reached a good degree of perfection in clinical practice. H owever\, there is still large space for improvements in what concerns qual ity assurance and treatment planning verifications. Indeed\, protons and h eavier ions offer a higher cell-killing effectiveness if compared to photo ns for a same level of absorbed dose\, property that is usually referred t o as Relative Biological Effectiveness (RBE). The RBE depends both on radi ation quality and on different biological parameters\, such as tissue type or endpoint considered\, whose knowledge is still limited. Nowadays\, a c onstant RBE value of 1.1 is currently used in radiotherapy treatments with protons\, although it is well known that this quantity varies with linear energy transfer (LET)\, increasing at the distal Bragg peak region [1]. T hus\, to take fully advantage of the increasing biological effectiveness o f protons\, recent studies aim at using dose and dose average LET (Ld) obj ective functions in treatment planning optimization\, working both on LET and dose distributions when optimizing the amount of radiation delivered t o the tumour volume [2]. \nThe approach for the calculation of Ld distribu tions in clinical proton beams may be both based on analytical models or o n Monte Carlo simulations. Since most of the Monte Carlo simulations used a very similar method to calculate Ld\, whose robustness was not tested fo r the variation of some critical parameters\, in a previous work we decide d to address this critical analysis comparing different methods of scoring Ld distributions produced by proton therapy beams in water in a voxelized geometry [3]. Furthermore\, in that work we took as reference values for Ld those obtained from microdosimetry calculations according to a formula proposed in [4]. The aim of this work is to further extend the calculation s performed in [3]\, making use of an improved and more efficient code for the calculation of microdosimetric quantities\, such as lineal energy and energy imparted per proton electronic collision. \n\nMethods and Results\ nIn our previous work\, in order to determine which Ld scoring method prov ided more reliable results\, we resorted to numerical stability against ch anges of geometry and production cuts\, carrying out the calculations with the Geant4 (GEometry And Tracking) toolkit [5-7]. The resulting simulatio ns\, with which we could come up with a robust Ld computation method in go od agreement with microdosimetry calculations\, were done at central beam axis and for primary protons only. \nIn this work\, our goal is to extend to off-axis voxels the calculation of Ld distributions for proton beams in water\, including the contribution of secondary protons. To this end\, we compared Ld distributions (2D) calculated for clinical proton beams with those computed from microdosimetry spectra obtained for sites of various s izes\, whose typical dimension ranged from 0.25 to 10 microns. With respec t to our previous work\, we implemented a new and more efficient Geant4 ap plication to score microdosimetric quantities\, which includes an algorith m capable of randomly place our scoring site in the region occupied by the proton track\, including its secondary electrons\, as shown in Fig. 1 (le ft). In doing this\, we accounted for electronic equilibrium along the pro ton track by choosing a world size at least equal to the maximum range of secondary electrons (RMax). In addition\, the approach of our new code is suitable to perform calculations with the Geant4-DNA physics package\, tha t simulates step by step interactions of particles in liquid water down to the eV scale [8\,9].\nOur preliminary results have confirmed the overall validity of our new code. We have also found a slight dependence\, with re spect to the site size\, of the deviations reported between our “macrosc opic” calculation of Ld distributions and those obtained from microdosim etry calculations\, as emerges in Fig. 1 (right). \n\nAcknowledgments\nThi s project has received funding from the European Union’s Horizon 2020 re search and innovation programme under the Marie Sklodowska-Curie grant agr eement No 675265\, OMA - Optimization of Medical Accelerators\, and from t he Spanish Ministry of Economy and Competitiveness under grand No FPA2016- 77689-C2-1-R.

Debido al indudable interés socio-económico del monzón para centenares de millones de personas\, actualmente se consider a esencial disponer de índices que cuantifiquen la intensidad de un monz ón para caracterizar con precisión su variabilidad interanual y estimar las posibles tendencias a largo plazo.\n\nExisten dos tipos de índices pa ra cuantificar la fuerza de un monzón: los índices dinámicos basados en el viento (normalmente al nivel de 850 hPa) y los termodinámicos basados \, en última instancia\, en la precipitación. Actualmente las series má s largas basadas en viento comienzan a mediados del siglo XX\, y utilizan como datos de entrada la componente zonal del viento a 850 hPa obtenida de productos tipo “reanálisis”. Las series basadas en precipitación se pueden remontar hasta los primeros años del siglo XX\, cuando las primer as estaciones de medición comenzaron a operar de forma continuada en las principales regiones afectadas por el monzón (África y el Sureste Asiát ico en particular). Los estudios realizados con estos índices han demostr ado que los monzones presentan variabilidad de largo periodo\, así como t endencias que en algunos casos son muy significativas\, como por ejemplo e l debilitamiento del monzón de África Occidental desde la década de 197 0 asociado a la sequía en el Sahel. Debido a su gran impacto\, la caracte rización de la variabilidad de los monzones a largo plazo es esencial\, p ero es prácticamente imposible encontrar medidas instrumentales de precip itación o viento antes del siglo XX en las regiones directamente afectada s por el monzón.\n\nLa única medida instrumental registrada de forma sis temática sobre las regiones monzónicas antes del siglo XX es la direcci ón del viento. Desde hace siglos\, miles de navíos han circunnavegado el globo registrando en sus cuadernos de bitácora\, diariamente\, la direcc ión observada del viento en la posición del barco. A raíz de numerosos proyectos internacionales\, miles de estos cuadernos han sido digitalizado s en incorporados a bases de datos digitales [1]. Recientemente\, se ha de mostrado [2] que es posible construir índices climáticos basados exclusi vamente en la dirección del viento (los denominados “índices direccion ales”) capaces de caracterizar\, de manera muy precisa\, los cambios en el trasporte de humedad asociados a la variabilidad estacional del viento. \n\nLos monzones pronto se perfilaron como candidatos obvios para ser cara cterizados mediante estos índices\, y este hecho fue el origen del proyec to INCITE (INstrumental Climatic Indexes. Application to the study of the monsoon-Mediterranean TEleconection)\, financiado por el Ministerio de Eco nomía y Competitividad en su convocatoria de 2013. Entre los objetivos de INCITE se encontraban el desarrollo de nuevas series instrumentales para caracterizar el monzón de África Occidental [3]\, el Monzón de la India [4] y el Monzón del Pacífico Occidental\, así como investigar su posib le conexión con el clima extratropical. \n\nEstando próxima la finalizac ión del proyecto\, el objetivo de esta presentación consiste en mostrar los fundamentos de los nuevos índices direccionales\, su íntima relació n con el trasporte de humedad y por tanto\, su capacidad para caracterizar la fuerza de un monzón desde mucho antes de que estuvieran disponibles o tras series instrumentales. Entre los principales resultados cabe menciona r:\n\n1. La detección de un periodo extremadamente lluvioso en África Oc cidental a finales del siglo XIX.\n\n2.

The relationship between chirality and magnetism has lo ng puzzled researchers. Recently\, layers of purely organic chiral molecul es have been shown to scatter electrons differently depending on their spi n [1] or to induce the appearance of strong spin polarization in initially unpolarized electron currents [2]\, opening up the possibility to use the se materials as spin filters or to control enantioselective reactions by m eans of spin polarization. In this work we report on an experimental study of different spin-related phenomena observed in layers of\nchiral molecul es adsorbed on single-crystal metal surfaces.\n\nMonolayer-thick films of chiral 1\,2-diphenyl-1\,2-ethanediol (DPED) have been studied by means of spin-polarized\, angle-resolved photoemission (SPARUPS) at the MAX-lab syn chrotron in Lund\, Sweden [3]. This molecule has two chiral centers locate d at the two carbon atoms of the ethane chain and presents two chiral enan tiomers which are designated according to their conformation and optical a ctivity as (R\,R)-(+)-DPED and (S\,S)-(–)-DPED. The molecular layers wer e adsorbed in ultra-high vacuum on top of ferromagnetic Co films epitaxial ly grown on Cu(100) whose in-plane spin polarization served as an in situ reference. The photoelectons emitted through adsorbed layers of both chira l enantiomers display a clear spin polarization at room temperature\, inde pendent of their binding energy. Nevertheless\, as Figure 1 shows\, the sp ins point along different directions in space: in-plane for (R\,R)-(+)-DPE D and out-of-plane for (S\,S)-(–)-DPED\, which makes the DPED molecule a prototype system to study enantioselective spin filtering. These results will be compared to other recent experiments carried out on a similar mole cule\, 1\,2-diphenylethylenediamine\, adsorbed on Cu(100)\, highlighting t he importance of the substrate and the charge transfer between this matter and the adsorbate. \n\nOne of the main characteristics of chiral molecule s is their optical activity\, that has long been known and studied for the visible and UV wavelengths but not so much in the x ray range. Enantio-pu re ultrathin films of DPED adsorbed on Cu(100) at 100 K have also been stu died at MAXlab using circularly polarized x rays absorption (XAS) at the c arbon K edge. XAS excites element-specific core electrons to empty levels in the ground state thus probing the molecule's electronic configuration. Pairs of spectra with circularly polarized x rays of opposite helicity wer e acquired and compared by taking their intensity ratio. Several clearly d ichroic features have been observed (see Figure 2) and assigned to transit ions into empty C–C and C–H π-type molecular orbitals\; as expected\, these dichroic ratios show opposite signs for the two enantiomers studied . However\, the magnitude of the asymmetry measured is much larger than ex pected for the natural circular dichroism associated to the chiral configu ration of the molecule. Preliminary analysis of these data indicates that the charge transfer between the Cu(100) substrate and the DPED molecules u pon adsorption might be enantio-selective and strongly polarized in orbita l moment. \n\nThe results described above suggest that this type of compou nds may be useful for molecular spintronics applications.\n\nhttps://indic o.ific.uv.es/event/2851/contributions/4485/ LOCATION:Facultad Química (USC) Aula Química Analítica URL:https://indico.ific.uv.es/event/2851/contributions/4485/ END:VEVENT BEGIN:VEVENT SUMMARY:TEMPERATURE DEPENDENCE OF LIQUID LITHIUM FILM FORMATION AND DEUTER IUM RETENTION ON HOT W SAMPLES BY LIDS AND TDS.

Although nowadays the use solid tungsten (W) components const itute the main investigated option for these requirements\, there are seri ous concerns over their limitations\, especially for the case of unmitigat ed heat flux and transients handling on the divertor. Liquid metal (LM) d ivertor concepts explore an alternative solution as their surfaces are\, i n principle\, renewable and unscathed to permanent degradation and disinte gration. Moreover\, evaporation and high edge non coronal radiation (vapor shielding) can help in this task\, reducing the power loads to the surrou nding walls. Among LM’s\, lithium (Li) is the most promising and studied material. Its employment has shown important advantages in terms of impro ved H-mode plasma confinement and heat handling capabilities. In such scen ario\, a possible combination of tungsten at the first wall and liquid Li at the divertor could be an acceptable solution\, but several issues relat ed with this material compatibility must be investigated. The co-depositio n of Li and hydrogen isotopes on W components could increase the associate d tritium retention and might represent an important hazard in terms of ra dioactive safety. In this work\, the co-deposition of Li and deuterium (D) on tungsten at different surface temperature (200ºC-400ºC) has been stu died by exposing W samples to Li evaporation under several D2 gaseous envi ronments. Deuterium retention in the W-Li films has been quantified by us ing Laser Induced Desorption Spectroscopy (LIDS). Additional techniques as Thermal Desorption Spectroscopy (TDS)\, Secondary Ion Mass Spectrometry ( SIMS)\, profilemetry and Flame Atomic Emission Spectroscopy (FAES) were im plemented to corroborate the retention results and for the qualitative and quantitative characterization of the W-Li films. The results show a negli gible (below the limit of detection) D uptake by the W-Li layer at Tsurfac e=225ºC\, when it is exposed to simultaneous Li evaporation and low press ure (0.67 Pa) D2 gas exposition. Pre-lithiated samples were also exposed t o higher D2 pressures (133.3 Pa) at different superficial temperatures (20 0ºC-400ºC). A non-linear drastic reduction in the D retention was found for increasing temperatures on the W-Li films that determined D/Li atomic ratios lower that 10-4 at 400ºC. The implication of these results in the potential implementation of this PFM’s solution is considered. Based on the experimental results\, an extrapolation of the D co-deposition on W-Li first wall areas in DEMO reactor designs is performed\, showing that the associated fuel retention in such hot first wall may be compatible with th e tritium inventory limitations.\n\nhttps://indico.ific.uv.es/event/2851/c ontributions/4483/ LOCATION:Facultad de Química (USC) Aula Química Analítica URL:https://indico.ific.uv.es/event/2851/contributions/4483/ END:VEVENT BEGIN:VEVENT SUMMARY:Photon Polarization in Radiative Bs Decays at LHCb DTSTART;VALUE=DATE-TIME:20170719T152500Z DTEND;VALUE=DATE-TIME:20170719T155500Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4480@indico.ific.uv.es DESCRIPTION:Speakers: Clara Remon Alepuz (PhD Student)\nThe photon polariz ation in radiative Bs decays has been studied for the first time at LHCb u sing Run I data.

However\ , PET imaging of plaque calcification in the coronary arteries is challeng ing because of the respiratory and cardiac motion as well as partial volum e effects. The objective of this work is to implement an image reconstruct ion framework\, which incorporates compensation for respiratory and/or car diac motion (MoCo) and partial volume correction (PVC)\, for cardiac 18F-N aF PET imaging in PET/CT.\n\nMaterials and methods: Realistic simulations (Biograph TPTV and Biograph mCT) and phantom acquisitions (Biograph mCT) w ere used. Different uptake values of the plaques (spherical shape\, 4 mm d iameter) were evaluated in the simulated datasets\, with lesion-to-backgro und ratios (LBR) of 10\, 20\, 50 and 70:1. The experimental phantom includ ed three plaque-type lesions of 18\, 31 and 36 mm3 respectively\, with a L BR of 70:1. After validation of the MoCo and PVC methods\, they were appli ed to four pilot 18F-NaF PET/CT patient studies. In all cases\, the MoCo-b ased image reconstruction was performed using the STIR software [3]. The P VC was obtained from a local projection (LP) method\, previously evaluated in preclinical and clinical PET [4]. We evaluated the noise in the image (measured in a background region) and the lesion-to-background ratio (LBR) values of the plaques\, using the maximum (LBRmax) voxel value within the segmented plaque.\n\nResults: After applying MoCo and PVC\, LBRmax increa sed by 200% to 1110% in the simulated data\, by 212% to 614% in the phanto m experiments and by 14% to 188% in the plaques with positive uptake obser ved in the patients. Similar noise values were observed in all images\, in contrast to the significantly higher noise observed when using respirator y or cardiac gating.\n\nConclusion: A combined MoCo and PVC approach for P ET/CT imaging was implemented within the STIR reconstruction framework. Th e simulated datasets\, experimental and patient data show significant impr ovement in the quantification of small coronary lesions when MoCo and PVC are taken into account.\n\nhttps://indico.ific.uv.es/event/2851/contributi ons/4474/ LOCATION:Facultad Química (USC) Aula Química Física URL:https://indico.ific.uv.es/event/2851/contributions/4474/ END:VEVENT BEGIN:VEVENT SUMMARY:The quest towards supramolecular networks from first principles DTSTART;VALUE=DATE-TIME:20170719T140500Z DTEND;VALUE=DATE-TIME:20170719T142500Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4458@indico.ific.uv.es DESCRIPTION:Speakers: Bruno Martínez Haya (Universidad Pablo de Olavide)\ nHow far into molecular complexity can we get from first principles?

In the particular class of composite multiferroics\, where magnetoe lectric coupling takes place owing to mechanical coupling (strain mediated ) between a ferroelectric material and a ferromagnetic material\, the sign of the net magnetization in the ferromagnet can not be selected uniquely by an electric field\, whatever is its sign or magnitude. This is because piezoelectricity and magnetostriction (the mechanisms that trigger magneto electric coupling) are both even functions of electric field and strain\, respectively.\n\n\nWithout overcoming this fundamental issue\, we will sho w by micro and macromagnetic characterization that magnetic memory effects present in the antiferromagnetic to ferromagnetic transition of FeRh can help to circumvent it. With this purpose\, we have characterised a PMN-PT/ FeRh structure. PMN-PT is a relaxor ferroelectric with record piezoelectri c coefficient\, and FeRh presents a large change in its lattice parameters while crossing the antiferromagnetic to ferromagnetic phase transition. T hus\, one can tune the magnetic order by means of electric-field\, by modi fying the magnetic transition temperature on FeRh via strain coupling betw een the piezoelectric substrate and the magnetic layer. First\, we will sh ow that FeRh phase transition shows thermal memory effect. After the FeRh magnetization is oriented in the ferromagnetic phase by an external magnet ic field and FeRh is brought to the antiferromagnetic phase by cooling it\ , if one measures the orientation of the magnetization again in the ferrom agnetic phase\, it partially recovers its initial state [1]. Secondly\, we also show that by the application of low electric field\, we can isotherm ally manipulate a large amount of magnetization. Magnetic imaging reveals that the electrically stimulated memory effect occurs thanks to the same m echanism that applies for the aforementioned thermal magnetic memory effec t [2]\, as sketched in Figure 1.\n\n[1] J.

To boost emitter-cavity interact ion\, i.e. coupling strength 𝑔\, ultrahigh quality cavities have been c oncocted yielding photon trapping times of µs to ms. However\, such high- Q cavities give poor photon output\, hindering applications. To preserve h igh photon output it is advantageous to strive for highly localised electr ic fields in radiatively lossy cavities. Nanophotonic antennas are ideal c andidates combining low-Q factors with deeply localised mode volumes\, all owing large 𝑔\, provided the emitter is positioned exactly right inside the nanoscale mode volume.

En la noche del 2 de abril de 1851 procedió a la ilumina ción mediante un arco voltaico de un edificio público por primera vez en España en esta misma ciudad\, Santiago de Compostela\, en el claustro de l antiguo edificio central de la Universidad (hoy Facultad de Geografía e Historia) [1]. La realización de esta demostración pública en esta ciu dad supuso un gran efecto desde el punto de vista educativo y divulgativo permitiendo a la sociedad compostelana de aquella época ser partícipe de un hito histórico y un gran acercamiento a la ciencia.\n La preparación científica y tecnológica no eran inaccesibles a otros científicos espa ñoles de la época\, pero los conocimientos específicos\, los elementos materiales y la determinación que se precisaban reunir para llevar adelan te el experimento no estaban al alcance de muchos. Pero estamos hablando d e un científico que lideró otros eventos de gran trascendencia [2]\, [3] . Como ya se ha mencionado\, se trata de la primera demostración de este tipo que se hace en España\, y por ello pensamos que se trata de un hecho que debe ser presentado y valorado en el Simposium de Enseñanza\, Divulg ación e Historia de la Física dentro de esta Bienal que tiene su sede en la ciudad donde aquel evento se llevó a cabo.\nLa intención de este tra bajo es el repaso de los aspectos más importantes del arco voltaico y de las pilas utilizadas para llevarlo a cabo como parte del hecho histórico de su primer uso en iluminación pública en España por Antonio Casares. Esta contribución también tratará de presentar un breve acercamiento a las pilas de combustible como fuente de energía con origen común a las p ilas Bunsen\, su inventor William Grove\, que permiten hoy imaginar un fut uro diferente basado en su uso\, como ocurrió con aquellas pilas que estu vieron presentes en la efeméride que aquí se presenta.\nLa experiencia o riginal de Antonio Casares\nEl experimento se llevó a cabo la noche del 2 de abril de 1851 [4] en el claustro del edificio central de la Universida d de Santiago de Compostela iluminando la Minerva de la Universidad y la t orre de la Iglesia de la Compañía. El montaje consistía en 50 pilas Bun sen en serie como fuentes de energía conectadas a un regulador Deleuil co n dos electrodos de grafito encargados de generar el arco voltaico.\nEl ex perimento diseñado por Casares contaba con 50 pilas tipo Bunsen como fuen tes de energía para conseguir la electricidad necesaria para la activaci ón y el mantenimiento del arco voltaico. Estos dispositivos fueron invent ados en 1940 por Robert Wilhem Bunsen a partir de una célula previa idead a por el científico galés William Robert Grove. La idea original de Grov e consistía en un sistema compuesto por un ánodo de zinc en ácido sulf úrico diluido y un cátodo de platino sumergido en ácido nítrico concen trado y ambos separados por una olla de cerámica porosa. Robert Bunsen mo dificó el cátodo de platino por una pieza de grafito\, material más bar ato\, dando lugar a una reacción con un potencial algo menor. Las reaccio nes químicas llevadas a cabo por este dispositivo son:\n3Zn↔〖3Zn〗^( 2+)+6e^-\n〖2NO〗_3^-+8H^++6e^-↔2NO+4H_2 O\n\ndando lugar a un potenci al teórico de 1.72 V\, inferior al de las celdas de Grove de 1.9 V.\n\nOt ro de los elementos importantes del experimento de Casares fue el regulado r Deleuil. Este equipo es el encargado de ir posicionando los electrodos d e grafito encargados de la formación del arco voltaico tras el desgaste q ue sufren. En este caso consta de un electrodo fijo y otro montado sobre u n sistema móvil regulado por un electroimán en serie con el propio arco. Este sistema también constaba de un espejo parabólico metálico que per mitía concentrar la luz y proyectarla sobre un edificio\, como se hizo aq uella noche.\nPor último\, el elemento más importante para la generació n de luz es el arco voltaico\, que se obtiene tras la ionización del aire entre ambos electrodos de grafito. A pesar de su uso\, el arco eléctrico no es apropiado como sistema de iluminación general porque\, independien temente de cuestiones tecnológicas (como el sistema de producción eléct rica) y del coste económico\, su brillo era excesivo\, resultando insopor table incluso a una distancia importante. También ha de tenerse en cuenta que no fue hasta más de 25 años después cuando se inventó la lámpara incandescente que sería utilizada para la implantación generalizada de la iluminación eléctrica en ciudades a finales del siglo XIX.\nLa experi encia hoy\nEn este trabajo también trataremos de plantear unos cambios en la experiencia de Casares con tecnología más innovadora actual\, como s on las pilas de combustible y que curiosamente cuentan con un estrecho ví nculo común con las baterías utilizadas en 1851\, su inventor William Gr ove.\nLas pilas de combustible son dispositivos capaces de generar electri cidad de manera directa a partir de la energía química contenida en el c ombustible\, tradicionalmente hidrógeno o alcoholes de bajo peso molecula r\, y el comburente\, el oxígeno del aire [5]. A pesar de ser ideadas por Grove solo 4 años después de la pila comentada anteriormente es hoy en día cuando se investigan con mayor interés\, suponiendo una gran alterna tiva energética para el futuro. Estos dispositivos se constituyen de dos electrodos\, catódico y anódico\, de platino nanoparticulado y una membr ana intercambiadora de iones como electrolito. Las reacciones que se lleva n a cabo en cada uno de los electrodos son:\n\nH_2→〖2H〗^++2e^-\n1⁄ 2 O_2+2e^-+2H^+→H_2 O\n\ndando lugar a un potencial teórico de 1.23 V que\, como vimos anteriormente es inferior al de las pilas Bunsen utilizad as en la experiencia original. Por ello\, es necesario situar más element os en serie con el fin de obtener similares valores de voltaje.\nEsta comp arativa tratará de dar un enfoque más moderno y actual al evento histór ico tratado anteriormente acercándolo al presente\, poniendo en valor la experiencia llevada a cabo en su día y presentando los cambios que se pod rían realizar con tecnología actual con común origen.\nReferencias\n[1] A.

However\, there are still many open questions in this nascent field which range from the actual spin polarization at metal/molecular interface s to the integration of molecular functionalities into spintronic devices. \nIn this talk I will review several experimental highlights from our grou p. \nBy using bathocuproine (BCP) and fluorinated copper phthalocyanine (F CuPc) we have unambiguously proved that spin transport occurs via molecula r levels\, finally dismissing any eventual role of metallic filaments or d efects in the electronic transport [2\,3]. Our experiments point to the cr itical role of the interfacial barriers for carrier injection into the mol ecular levels. Moreover\, in the FCuPc case we have shown concomitant spin transport and photoresponse. Thanks to the emergence of two molecular-bas ed properties\, four distinguishable resistance states adjustable by light and/or magnetic field can be configured in a simple 2-bit memory cell [3] . Further recent results in this wide topic\, merging spin transport with the photovoltaic effect of C60 fullerenes will be shown [4].\nI also will present spin valves based on rare-earth quinolines.

[1] The interest on this material increased when it w as very recently proposed to be the first example of a new class of materi als dubbed type-II Weyl semimetals.[2] The electronic band structure of a type-II Weyl semimetal shows tilted Weyl cones that arise from topologica lly protected crossings of valence and conduction bands causing touching p oints between electron and hole pockets near the Fermi level. The projecti on of these so called Weyl points onto a surface must be connected by Ferm i arcs. In WTe2 the surface Fermi arcs terminate inside the bulk electron and hole pockets where the surface states strongly hybridize with bulk sta tes and can no longer be observed experimentally. Additionally\, WTe2 is n on centro-symmetric\, which implies inequivalent top and bottom surfaces w ith a distinct electronic structure that could not be resolved so far. Tog ether\, these subtleties render the identification of the topological natu re of the Fermi arcs challenging. \nWe present several advances towards a comprehensive understanding of WTe2 electronic structure. Using micro-focu s laser-ARPES we resolve for the first time the distinct electronic struct ure of both inequivalent top and bottom (001) surfaces. The presence of la rge surface state Fermi arcs on both surfaces is established. [3] Using su rface electronic structure calculations we further demonstrate that these Fermi arcs are topologically trivial and that their existence is independe nt of the presence of type-II Weyl points in the bulk band structure. Cont rary to common believe\, the observation of surface state Fermi arcs is th us not suitable to robustly identify a type-II Weyl semimetal. [4] Finally \, we show that the bulk Fermi surface is formed by three-dimensional elec tron and hole pockets with areas that are found to be in good agreement wi th transport experiments with the exception of small hole pockets that hav e not been observed in quantum oscillation experiments.

Moreover\, the e merging technology of Space-Division Multiplexing [1] has recently attract ed a lot of attention due to the increasing demand of high-capacity optica l transmissions and the proximity of the capacity crunch\, being Mode-Divi sion Multiplexing (MDM) one of the solutions proposed to take profit of th e spatial degrees of freedom working with multimode channels. In this cont ext\, integrated MDM devices are being developed using many different appr oaches including Supersymmetric (SUSY) optical devices [2] which are one o f the most promising alternatives to standard spatial multiplexing devices offering global phase-matching and efficient mode conversion in an integr ated and scalable way. However\, the main drawback of SUSY optical devices is their lack of robustness against variations of parameter values such a s light's wavelength and their sensitiveness to experimental imperfections . This can be solved making use of Spatial Adiabatic Passage (SAP) techniq ues which have been proposed and experimentally reported as a high-efficie nt and robust method to transfer a light beam between the outermost wavegu ides in a system of three identical evanescently-coupled waveguides [3].\n \nWe propose to combine SUSY and SAP techniques to design an efficient and robust device which can be used for multiplexing/demultiplexing spatial m odes\, to manipulate and study the modal content of an input field distrib ution or to filter signals and remove non-desired modes [4]. We demonstrat e that a system of three coupled waveguides\, with two identical step-inde x external waveguides and a supersymmetric central one\, engineered along the propagation direction to optimize SAP for the first excited spatial mo de of the step-index waveguides\, can be used to demultiplex a superpositi on of the two lowest (m=0\,1) transverse electric TEm spatial modes. Thus\ , we obtain a great improvement in terms of robustness and efficiency with output fidelities F>0.90 for a broad range of geometrical parameter value s and light's wavelengths\, reaching F=0.99 for optimized values at the te lecom wavelength λ=1.55 µm.\n \nAlthough we have designed the device to operate at telecom wavelengths\, it can be optimized to work at differe nt wavelengths and moreover\, due to its high efficiency for a broad wavel ength range\, it may be used for mode filtering of light pulses and it is fully compatible with wavelength division multiplexing. As a proof of prin ciple\, we have focused on the simplest possible case for which only two T E spatial modes can propagate through the step-indexplanar waveguides but this configuration can be generalized to a higher number of TE modes\, to transverse magnetic modes or even to orbital angular momentum modes in mul timode optical fibers. In addition\, the device can be engineered to separ ate different modes by applying SUSY reiteratively and more complex device s can be constructed in order to demultiplex N spatial modes in an efficie nt and robust way by coupling in series different devices. Finally\, the h igh obtained fidelities open promising perspectives in the field of quantu m integrated photonics to\, for instance\, prepare and manipulate quantum states with minimal errors or by taking profit of the high dimensional Hil bert space associated to spatial modes.\n\n[1] D.J.

Conversely\, applying a voltage to a dielectric mate rial will cause it to bend spontaneously\, due to the converse (or inverse ) flexoelectric effect. Both direct and inverse flexoelectricity scale up with the inverse of the thickness of the material\, so this phenomenon is gaining prominence with the advent of nanotechnology. On the other hand\, and despite its surge in popularity\, there have been –until recently- e normous gaps in our knowledge about flexoelectricity\, including such fund amental questions as the actual order of magnitude of the intrinsic flexoe lectric coefficients\, the role of surfaces in the total flexoelectric per formance\, or even whether flexoelectricity can only happen in insulators. \n\nSeeking to answer these questions\, the PhD project of Jackeline Narv áez has studied the flexoelectricity of single crystals. Her results reso lve previous controversies by establishing that (i) the intrinsic flexoele ctric coefficients of even the best flexoelectric materials does not excee d a few nC/m\; (ii) in relaxors (and some ferroelectrics)\, there are addi tional contributions from polar nanodomains that can elevate the total fle xoelectric coefficient to the µC/m range\; (iii) the contribution of surf aces is at least as big –and sometimes bigger- as intrinsic bulk flexoel ectricity and\, contrary to previously thought\, it is (at least indirectl y) measurable\, and (iv) semiconductors can also be flexoelectric\, and mo reover their flexoelectric coefficients can reach the mC/m range\; this is one million times more than the intrinsic flexoelectricity of dielectric insulators. \n\nIn my talk\, I will give an overview of the field of flex oelectricity and a summary of the main results (contextualzing their signi ficance) from the PhD thesis of Jackeline Narvaez\, ex-aequo winner of the GEFES award to the best thesis in experimental condensed matter physics.\ n\nhttps://indico.ific.uv.es/event/2851/contributions/4427/ LOCATION:Facultad Química (USC) Aula Química Inorgánica URL:https://indico.ific.uv.es/event/2851/contributions/4427/ END:VEVENT BEGIN:VEVENT SUMMARY:Measurement-Device-Independent Quantum Key Distribution with Infor mation Leakage DTSTART;VALUE=DATE-TIME:20170718T160500Z DTEND;VALUE=DATE-TIME:20170718T162500Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4426@indico.ific.uv.es DESCRIPTION:Speakers: Weilong Wang (University of Vigo)\nMeasurement-devic e-independent quantum key distribution (MDI-QKD) is proposed to remove all the detection side-channels in quantum communication systems.

A specific field of interest is the u nderstanding and development of storage devices for light gases\, speciall y for energy applications (hydrogen) or environmental reasons (CO2\, H2S). Carbon nanotubes have been largely studied with the idea of designing pos sible storage devices for H2 since the late 1990s [3]. However\, a complet e quantum dynamics description of the diffusion mechanism inside these str uctures is still lacking.\n\nHere we present a quantum mechanical study of the diffusion of the H2 molecule along a narrow (8\,0) Single-walled Carb on Nanotube (SWCNT). Following previous works by our group [4] we have mod elled the system considering all the degrees of freedom (DOFs\, internal a nd translational) of the hydrogen molecule and a rigid nanostructure.  Th e cylindrical shape of the potential energy surface\, showing five bound D OFs and one unbound DOF\, has prompted us to develop an exact diabatizatio n formalism separating two sets of weakly coupled degrees of freedom: on o ne hand\, the unbound coordinate corresponding to the motion of the center of mass of H2 along the nanotube’s axis\, and in the other the remainin g 5 DOFs\, which are effectively confined by the nanostructure. By applyin g a complete separability assumption to the confined and unbound DOFs we h ave also developed an adiabatic approximation to the Hamiltonian\, which i ncreases the algorithm efficiency while maintaining the accuracy of the re sults. Both approaches have been employed to simulate Hydrogen diffusion a long the SWCNT at temperatures in the 45-135 K range. The computational ad vantages provided by both method have enabled us to propagate the wave fun ction beyond 15 picoseconds using the State Averaged - MCTDH [5] code\, re vealing a remarkable resonant structure as well as a noticeable tunnelling effect.\n\nAcknowledgments\nFinancial support from the Spanish Ministerio de Economia y Competitividad (CTQ2013-41307-P) and Generalitat de Catalun ya (2014- SGR-25) is acknowledged.

Very fine det ails of such interactions can be unravelled using rotational spectroscopy thanks to its great resolving power. However\, rotational spectroscopy is usually restricted to the gas phase. In the condensed phases\, interaction s are usually so strong that rotational features are overshadowed. An exce ption is liquid helium where interactions are exceptionally weak. Furtherm ore\, its properties are strongly affected by quantum effects. Also\, it i s an attractive model substance for theory and for experiment: (i) helium atoms\, having only two electrons\, greatly facilitate high level ab initi o calculations of clusters. (ii) At the temperatures where helium becomes liquid all other substances freeze. Liquid helium is therefore one of the purest\, if not the purest of all condensed substances. This exceptional p urity has recently been exploited for the investigation of nucleation\, gr owth and solidification of nanoparticles [1].\n\nThis presentation will hi ghlight two recent experiments where rotational spectroscopy has been push ed to new limits. The full rotational spectrum of a molecular complex was derived using femtosecond wave packet spectroscopy. In another experiment in liquid helium\, molecules were\nidentified in their lowest rotational q uantum state in thermal equilibrium.\n\nImpulsive alignment of clusters in a beam and fluorescence spectroscopy in bulk helium\n\nWe have excited a supersonic beam of small C2H2-Hen clusters non-resonantly with intense fem tosecond laser pulses - a technique called impulsive alignment - thereby c reating wave packets composed of rotational eigenstates. The clusters were then probed with a second laser pulse after a set time delay which led to Coulomb explosion. Using the fragment velocity distribution of the C2H2 m olecules the state of alignment was determined and the propagation of rota tional wave packets was measured in the time domain. A Fourier-transform o f the time-spectrum yielded the pure complete rotational spectrum of C2H2- He in excellent agreement with theory [2]. The spectrum showed strong delo calisation of the complex indicating liquid-like character. The excited co mplex nevertheless rotated coherently over the entire duration of the expe riment of 600 ps and showed no signs of dephasing [3].\n \nThese results d emonstrate that impulsive alignment is well suited to derive structural an d dynamical information from clusters\, including weakly bound complexes. Production of these complexes requires strong cooling with the consequence that normally only the lowest rotational quantum states are populated. Un like traditional frequency domain spectroscopy\, where selection rules lim it the quantum number of states to ΔJ=1\, impulsive alignment provides th e control that is necessary to excite and probe all J levels\, up to the d issociation threshold. \n\nIn another experiment bulk helium was electroni cally excited using a corona discharge\, creating a rich fluorescence spec trum which was measured as a function of temperature and pressure. Intense fluorescence in the visible region showed the rotationally resolved d  u+ b3g transition of He2*. With increasing pressure\, the rotatio nal lines merged into single features. The observed pressure dependence of line width\, shapes and line shifts established that within liquid helium excimers are either solvated\, and cold\, or ‘boiling’ within rotatio nally hot gas pockets. Increase of hydrostatic pressure was found to rotat ionally cool the excimers at a rate of at least 1010 to 1011 K/s in collis ions with the liquids until they occupied the lowest available quantum sta te [4].\n\nThese findings are important with regard to the quest of achiev ing greatest possible control over molecules\, including cooling their deg rees of freedom. Also\, they suggest that it should be possible to investi gate liquid and superfluid helium at the nanoscale over a large pressure a nd temperature range using molecules as rotational probes. Previous experi ments used helium droplets and were therefore restricted to fixed pressure s and temperatures. They suggest that by additional control of pressure\, temperature and thermodynamic phase unprecedented insight into the structu re of solvation layers and interfaces can be achieved.\n\nFunding is ackno wledged from the Royal Society\, The Leverhulme Trust\, Erasmus\, COST act ion MOLIM\, CONACYT\, the Iraq government and the University Joseph Fourie r for a visiting professorship for KvH.\n\nReferences\n[1] H.

For HCl interacting with water molecules - one added after the other - there is convincing evidence that an ion pair\, and thus the dissociated acid molecule\, can be stabilized using a minimum number of only four water molecules (see Fig. 1) [1\,2]. H owever\, this number has been questioned both on the experimental [3–6] and the theoretical sides [7]. In this respect\, an experiment appeared re cently in the literature [8] which suggested a new approach. In this exper iment the dipole moment of HCl•(H2O)n clusters was measured as a functio n of the number of water molecules (see Fig. 2). The key result of those m easurements was a noticeable rise of the total dipole moment of these clus ters when n=6. A tempting explanation was to assign this sudden rise in th e dipole moment to the dissociation of the HCl molecule.\n\nIn this work\, ab initio path integral calculations were performed in order to try to di sentangle the controversy of whether it is 4 or 6 water molecules the mini mum required to dissociate the chloridric acid. Our results show that meas uring the dipole moment of HCl•(H2O)n clusters does not give any informa tion about the dissociative state of the HCl molecule. In addition\, a det ailed analysis of thermal and quantum effects provides a much clearer pict ure of the acid dissociation process in microsolvated environments. \n\nTh e Cluster of Excellence “RESOLV” (EXC 1069) funded by the Deutsche For schungsgemeinschaft (DFG) is gratefully acknowledged along with computer t ime support from HPC-RESOLV\, HPC@ZEMOS\, BOVILAB@RUB and RV-NRW.\n\n\nRef erences\n\n[1] A.

Manzanares (Universidad de Valencia)\nLigand -stabilized metal nanoparticles (NPs) have become essential in many active areas of research. A narrow size distribution is essential for controllin g their physicochemical properties and for increasing the degree of orderi ng in NP superlattices. During NP synthesis\, coalescence and Ostwald ripe ning induce polydispersity. Digestive ripening (DR) is a widely-used\, pos t-synthetic step that reduces the dispersity and produces narrow size dist ributions of ligand-stabilized NPs of noble metals\, transition metals\, m etal sulfides and halides\, II-VI semiconductors\, lanthanide oxides\, as well as alloys and core-shell bimetallic NPs. DR involves heating the as-p repared\, polydisperse colloidal solution in the presence of excess strong capping ligand at or near the boiling point of the solvent under reflux. A ligand-exchange reaction induces the redistribution of atoms among NPs a nd leads to a narrow size distribution. In spite of the experimental effor ts to provide insights\, the mechanisms of DR are not yet known. We presen t a DR theory that clarifies the factors that determine the size distribut ion of charged NPs.\n\nhttps://indico.ific.uv.es/event/2851/contributions/ 4411/ LOCATION:Facultad Química (USC) Aula Químca Orgánica URL:https://indico.ific.uv.es/event/2851/contributions/4411/ END:VEVENT BEGIN:VEVENT SUMMARY:HITOS Y DIDACTICA DE LA TERMODINÁMICA EN EEEMM DTSTART;VALUE=DATE-TIME:20170719T170000Z DTEND;VALUE=DATE-TIME:20170719T171500Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4410@indico.ific.uv.es DESCRIPTION:Speakers: francisco sotres (grupo de didactica e historia de l a fisica y quimica)\nAunque en los currículos actuales de Química de las EEMM la docencia de conceptos tan abstractos como la entalpía\, la en tropía y la energía libre\, se proponen ya en 1º de Bachillerato (antes en 2º) como meros algoritmos aplicados a casos concretos de predicción de espontaneidad de reacciones químicas\, entalpía de procesos\, etc.. e l hecho es que este tema sigue siendo el de peor comprensión de todo el t emario para los chicos y el más incómodo de impartir para los profesore s críticos.

Nuclei with a large N/Z ratio in this area of the table of iso topes are of great interest to test nuclear models and provide information about single particle states. Stringent tests of the models can be provid ed by the reduced electromagnetic transition probabilities connecting nucl ear states.\nIn this work we have used fast-timing and gamma spectroscopy to investigate five Sn nuclei\, including the doubly magic 132Sn\, the two neutron hole 130Sn and two-neutron particle 134Sn\, and the one-neutron h ole 131Sn and one-neutron particle 133Sn. The Sn isotopes were studied at the ISOLDE facility\, where their excited states were populated in the bet a-decay of In isomers\, produced in a UCx target unit equipped with a neut ron converter. The In isomers were ionized using the ISOLDE Resonance Ioni zation Laser Ion Source (RILIS)\, which for the first time allowed isomer- selective ionization of indium. The measurements took place at the new ISO LDE Decay Station (IDS)\, equipped with four highly efficient clover-type Ge detectors\, along with a compact fast-timing setup consisting on two La Br3(Ce) detectors and a fast beta detector. The setup incorporated a tape transport system to remove longer-lived activities.\nIndium isotopes with masses ranging from 130 to 134 were produced. The RILIS isomer selectivity made it possible to produce odd-mass In isotopes with a clean separation between the 9/2+ and 1⁄2– beta-decaying isomers. For the even isotopes \, such as 130In\, it was also possible to separate the 5+\, 10– and 1 – isomers.\n We report on the lifetime of the 331-keV 1/2+ level in 131S n\, which provides information on the M1 transition to the ground state an d on its degree of forbiddeness\, similar to what has been recently been m easured for 129Sn [2]. We also report on the expanded level scheme of the 131Sn and the preliminary lifetimes of excited states populated in the de cay of the 131In (21/2+) isomer. \nThe 132Sn was studied by means of the b eta-decay of 132In\, and also from the beta-n decay of the 133In 1/2– is omer and the 133In 9/2+ g.s. separately. We present the new level scheme\, which have been enlarged with more than 8 new levels and 40 gamma transit ions. A crosscheck of previously measured known lifetimes is also provided [3].\n\nReferences\n[1] A. Korgul et al\, Phys Rev Lett 113\,132502(2014) \n[2] R.

It is the building bl ock of all major electronic information processing components such as micr oprocessors\, memory chips and telecommunications microcircuits. By shrink ing its size generation after generation the computational performance\, m emory capacity and information processing speed has increased relentlessly . However\, the process of miniaturization is bound to reach its fundament al physical limits in the next decades.\n\nNew computing paradigms are hen ce paramount to overcome the technical limitations of silicon technology a nd continue increasing the computation performance beyond simple multi-cor e approaches. Quantum computing – based on computing with interacting tw o-level quantum systems or qubits- offers exponential speed-up over severa l classical algorithms [1-3] and it is hence one of the most sought-after alternatives to conventional computing. However\, finding the optimal phys ical system to process quantum information and scale it up to the large nu mber of qubits necessary to run the aforementioned algorithms remains a ma jor challenge. Paradoxically\, we are now starting to see that silicon tec hnology itself could offer an optimal platform on which to fabricate spin- based scalable quantum circuits: Quantum computing with silicon transistor s fully profits from the most established industrial technology to fabrica te large scale integrated circuits while facilitating the integration with conventional electronics for fast data processing of the binary outputs o f the quantum processor\; all this offering long electron spin coherence t imes [4]. \n\nResults\n\nIn this talk\, we present a series of results on fully depleted silicon-on-insulator (FD-SOI) transistors at miliKelvin tem peratures that demonstrate this technology can provide a platform for high -integration spin qubit architectures. Firstly\, we report the formation o f a tunnel coupled double quantum dot (DQD) at the top-most edges of the t ransistor\, as the building block for implementing charge and spin qubits [5\,6]. By using split-gate electrodes we independently control the charge occupation of the system down to the few-electron limit. Measurements of the charge and spin state of the system are done via in-situ dispersive ga te-based radio-frequency reflectometry [7-9]\, see Fig 1. This technique\ , that interfaces the quantum system to a high-frequency electrical resona tor\, removes the need for external charge sensors and provides a compact and sensitive way (δq=37 µe/√Hz) to detect charge motion\, favouring t he prospects for scalability. Furthermore\, we show coherent control the c harge occupancy of the DQD in the single-electron regime using microwave e xcitation. We perform Landau-Zener-Stückelberg interferometry experiments to assess the charge coherence time of the system\, T2*=250 ps [10]. \n\ nFinally\, we present a set of experiments that demonstrate the potential to scale FD-SOI technology to a large number of qubits and interface them naturally with conventional binary FD-SOI transistors: We present a quadru ple-gate transistor on FD-SOI that can be reconfigured to host up to four quantum dots in silicon [11] showing that this approach can be readily ext ended to fabricate a 1D line of interacting qubits. Furthermore\, we show a monolithic approach to fabricate hybrid classical-quantum circuits in wh ich the qubit readout is controlled by the digital state of the convention al transistor\, demonstrating the first steps towards time-based multiplex ing qubit readout. \n \nOverall\, our results open up the possibility to o perate compact transistor technology as electron spin qubits and demonstra te the potential of split-gate FD-SOI technology as a hardware for compact and scalable hybrid quantum computing architectures.\n\nAcknowledgments\n \nThis research is supported by the European Community’s Seventh Framewo rk Programme (FP7/2007-2013) through Grant Agreement No. 318397 (http://ww w.tolop.eu) and Horizon 2020 through Grant Agreement No. 688539 (http://mo s-quito.eu).

Of particular importance are some nuclides produced during the s-process which are radioactive\, with h alf-lives from years to Gy\, so its decay process competes with the neutro n capture chain: these nuclides are known as branching points. The measure ment of the neutron capture cross section of these elements is crucial to determine the local abundance pattern around the branching point\, which y ields information of the s-process stellar environment\, such as temperatu re\, neutron density or pressure. 204Tl (T1/2=2.78 y) is a very interestin g branching point. In the recurrent He-flashes of AGB stars\, 204Tl can ei ther β-decay to the s-only nuclide 204Pb or capture another neutron\, thu s producing 205Tl. which in some stellar environments can decay to 205Pb. On the other hand\, neutron capture on 204Pb also yields 205Pb (T1/2=1.5× 107 y). Therefore\, the value of the 204Tl capture cross section is necess ary to determine precisely the primordial 205Pb/204Pb abundances ratio\, w hich would allow one to estimate the time span since the last s-process ev ents that contributed to the elemental composition of the Solar System.\n\ nIn the year 2015\, the cross section of the 204Tl(n\,γ) reaction was mea sured for the first time ever employing four C6D6 scintillation detectors in the neutron time-of-flight facility n_TOF at CERN. The sample was a 203 Tl oxide pellet enriched to 4% in 204Tl. The 204Tl total mass was 9 mg\, w ith a total activity of 160 MBq.\n\nIn this talk several aspects of this c apture cross section measurement will be covered\, from the experimental m ethods and the extraction of the cross section and other important capture reaction parameters\, to the final application of the results on s-proces s nucleosynthesis.\n\nhttps://indico.ific.uv.es/event/2851/contributions/4 391/ LOCATION:Facultad de Química (USC) Aula Física Química URL:https://indico.ific.uv.es/event/2851/contributions/4391/ END:VEVENT BEGIN:VEVENT SUMMARY:Solar cell architectures by combining graphene and carbon nanotube s with silicon DTSTART;VALUE=DATE-TIME:20170719T164500Z DTEND;VALUE=DATE-TIME:20170719T171500Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4389@indico.ific.uv.es DESCRIPTION:Speakers: Isabel Montero (CSIC)\nThere is intensive efforts in exploring innovated solar cell structures with high performance and cost- effective manufacturing methods.

They are the irrefutable proof that st ars are not immutable objects\, but they change with time\, they evolve an d\, often\, they have a rapid and certainly showy death. About 90% of the stars in the sky are expected to end their life as PNe\, those bright enou gh to ionize the gas and dust that they expelled while contracting towards the White Dwarf phase\, but that are not massive enough to explode as sup ernovae. PNe are important to understand the chemical evolution of our Gal axy (and also of other galaxies) because they enrich the interstellar medi um with products synthetized in the stellar interiors and molecules conden sed in the circumstellar shells around their dying bodies. One of the most important problems in current PNe studies is the fact that their distance s are poorly known [1]. Paradoxically\, these objects are being used as ex tragalactic distance candles because they are easy to detect and\, general ly\, high luminosity objects.

Two challenges arise with the use of t hese radionuclides: their large positron range\, which compromises the ach ievable spatial resolution of the system\, and the emission of cascades of gamma-rays in coincidence with positrons\, which complicates quantitative PET imaging. In this work we used the Monte Carlo simulation tool PeneloP ET developed by our group to model the effects of positron range and promp t emissions in PET image quality. Later\, we used this modeling to correct PET images for positron range and prompt gamma emissions effects. Further \, a method for improving the quantification of PET images was also implem ented and evaluated. Finally\, we modified our simulation tool in order to simulate and analyze triple coincidences in PET.\n\nMethods: We used Pene loPET to model positron range for different radionuclides in several biolo gical tissues. Positron range (PR) distributions for each radionuclide-tis sue combination have been determined and PeneloPET estimations have been c ompared with previous results found in the literature. In addition\, a tis sue-dependent and spatially variant positron range correction (TDSV-PRC) m ethod has been developed and evaluated. We have modified PeneloPET to accu rately simulate the decay cascades for non-pure emitters of interest for P ET imaging\, and we implemented and evaluated a local projection (LP) meth od for partial volume correction (PVC). Finally\, we implemented a framewo rk to simulate and analyze triple coincidences in PET. We validated our si mulation tool by comparison of our simulated estimations against experimen tal measurements performed in a modified prototype of the Argus PET/CT sca nner. \n\nResults: The obtained PeneloPET PR estimations were consistent w ith previous literature. The TDSV-PRC yields artifact-free reconstructed i mages for large-PR radionuclides\, like 124I or 68Ga\, when range correcti ons are taken into account. The LP-PVC method\, together with PRC\, provid es significant improvement in the quantification of PET images. Good agree ment between the simulated and experimental double and triple coincidences spectra was obtained.\n\nConclusion: Monte Carlo simulations may guide th e modeling and correction of the main effects that degrade image quality i n PET imaging with non-conventional radionuclides.\n\nhttps://indico.ific. uv.es/event/2851/contributions/4383/ LOCATION:Facultad Química (USC) Aula Química Física URL:https://indico.ific.uv.es/event/2851/contributions/4383/ END:VEVENT BEGIN:VEVENT SUMMARY:Dissipative effects in fission investigated in complete kinematics measurements DTSTART;VALUE=DATE-TIME:20170717T142500Z DTEND;VALUE=DATE-TIME:20170717T144500Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4382@indico.ific.uv.es DESCRIPTION:Speakers: Jose Luis Rodriguez Sanchez (USC)\nA complete descri ption of the fission process still represents a challenge\, despite the re cent progress based on time-dependent Hartree-Fock models [1]. Statistical models provide a tool to describe fission probabilities at excitation ene rgies around the fission barrier. This approach is justified because\, und er such conditions\, statistical times dominate over the typical timescale s for the coupling between intrinsic and collective degrees of freedom (~1 0-21s). At high excitation energies\, pre- and postscission particle emiss ion and fission probabilities [2\,3] indicate that simple statistical appr oaches are not valid and models\, describing the dynamics of the process\, are required. These models are based on transport equations\, e.g. Fokker -Planck or Langevin\, where the main ingredients are the potential landsca pe and the friction and inertia tensors [4]. The friction parameter is par ticularly interesting because it quantifies the magnitude of the coupling between collective and intrinsic degrees of freedom in fission. \nIn this work\, we propose to investigate these effects by taking advantage of prot on-induced fission reactions at relativistic energies for producing highly -excited fissioning nuclei with low angular momentum\, where dissipative e ffects should manifest in a clear way. The SOFIA setup together with the i nverse kinematics technique were used for the first time to measure in coi ncidence the mass and atomic number of the two fission fragments with good resolution [5]. These high-quality data allowed us to obtain new observab les in fission.

The traditional ways to control their motion areis by means ofusing magnetic fields and spin polarized currents. MAlso\, magnet ic domain motion driven by temperature gradients hasave been also shown in theoretical [1\,2] and experimental [3] works\, opening the door to use t hermal control of domain wall in future spintronicmagnonics devices. On th e other hand\, the possibility to control the magnetic properties using me chanical stress is currently being investigated with promising results [4\ ,5]. In this work we will focus in these two ways to control the dynamics of magnetic textures\, studying: 1) the dynamics of complex magnetic text ures\, like spin spirals or skyrmions\, induced by thermal gradients. 2) t he possibility to use acoustic waves as the driven force for the DW motion . \n\nMotionvement induced by temperature gradients\nThe existence of a te mperature gradient in the system induces a non-equilibrium populationsitua tion of magnons. The density of magnons excited in the hotter isare larger than that in the cold section of the system\, leading to a flow of magnon s from the hotter area to the colder one. When the magnons pass through th e DW\, they transfer angular momentum to the DW and as a consequence of th at effect the DW moves to the colder area. Recently\, F. Schlickeiser et. al have proposed that in parallel to the transfer angular momentum other m echanism may exist responsible of the movement of magnetic structures into a temperature gradient. Such mechanism is related to the maximization of the entropy of the system by displacing the DW from the colder to the hott er area [6]. In our work\, we analyze the dynamics of two dimensional non- collinear magnetic textures subject to a temperature gradient. In order to do that\, numerical calculations of the dynamics of a helical spin spiral (HSS)\, a skyrmion lattice and isolated skyrmions are carried out in atom istic spin models with the stochastic Landau-Lifshitz-Gilbert equation of motion. \n \nFig1: Helical spin spiral (HSS) velocity versus temperature g radient for\, α=0.2. The open symbols present our numerical data\, the li nes are from linear fits to the positive and negative temperature gradient dT/dx.\n\nOur findings show that in systems with spin spirals the lack of mirror symmetry leads to the effect that the velocity of the moving spira l depends on the sign of the temperature gradient with respect to the chir ality of the HSS. This result is clearly shown in the Fig. 1\, where the v elocity of a left-handed helical spin spiral (HSS) versus the temperature gradient is displayed for a value of the damping constant\, α=0.2. .The d ata points (empty symbols) are from the numerical simulations while the li nes represent linear fits to the positive and negative temperature gradien t \, dT/dx . Furthermore\, we observe that the movement of isolated skyrmi ons is determined by the temperature gradient and the Magnus force\, and i n the case of a lattice of skyrmions the interaction between skyrmions pla ys a fundamental role.\n\nMotionvement induced by acoustic waves\n In our study of the mechanical control of the DW motion we use micromagn etic simulations to investigate whether it is possible to move a DW using mechanical waves\, a possibility that has been suggested recently [43]. To do that we have developed a novel numerical scheme to solve both: magneti zation dynamics and elastodynamics equations self-consistently\, similar t o the one presented in [54] but using a finite difference scheme. We consi der a Ni nanowire of a rectangular cross section (50 x 20 nm) with a head to head DW in the middle. Circularly polarized elastic waves are excited ion one end of the nanowire by imposing a periodic deformation of amplitud e uo and frequency ʋ=10Ghz. The mechanical excitation induces magneto-ela stic waves (MEW). When they reach the DW they excite it\, exerting a torqu e on such magnetic texture which induces a movement of the DW towards the source of the elastic excitation. This result is clearly shown in the Fig. 2\, where the x-component of the averaged magnetization (which is related to the position of the DW) is plotted as a function of time for several v alues of the amplitude of the mechanical excitation. \n \nFig1: Time evol ution of the averaged x-component of the magnetization of the nanowire as a function of the amplitude uo of the acoustic excitation.\nAcknowledgment s\nThis work was partially supported by No. SA090U16 from the Junta de Cas tilla y Leon.\nReferences\n\n[1] D.

In general\, the main advantage of proton beams\, as compared with photon conventional rad iotherapy\, is related to the shape of the depth dose distribution curves they produce\, with a sharp maximum dose known as the Bragg peak. Since th e depth of the Bragg peak can be regulated according to the beam nominal e nergy\, each radiation field used in a treatment plan can be energetically adjusted so that its maximum dose is placed within the prescribed tumor v olume (PTV). Another important advantage of proton therapy\, also with res pect to light-ion radiation therapy\, corresponds to the exit dose\, i.e. the dose deposition in tissues and organs downstream the tumor volume\, wh ich is negligible with respect to the dose deposited at beam entrance and at the Bragg peak region.\n\nHowever\, the high gradient dose regions prod uced by proton clinical beams calls for a very accurate modeling of proton propagation through organs and tissues\, either as for linear energy tran sfer (LET) and lateral spread calculations. Especially\, it is important t o reduce the uncertainties on the value of the mean ionization potential ( I-value) in materials relevant for the clinical practice\, such as water\, to increase the accuracy of LET calculations\, and subsequently the beam range calculation in a patient [2]. Furthermore\, the radiobiological resp onse of tissues irradiated with protons has been proved to be more complex as compared with photon beam irradiation. Although it is currently establ ished that the relative biological effectiveness (RBE) of protons is 10% l arger than mega-voltage photons [3]\, several models and experimental resu lts have been published recently suggesting a higher RBE value around the Bragg peak region [4].\n\nIn this contribution\, we show two research acti vities currently under development by our group within the context describ ed above\, in which simulations with the Geant4 Monte Carlo toolkit [5-7] are playing an important role. A first activity aims at providing an accur ate I-value for water by means of modeling energy deposition curves measur ed in water with different light ion beams by Schardt et al. at GSI (Darms tadt\, Germany) [8]. Concretely\, they obtained the energy deposition as f unction of the absolute depth in water for protons and ions lighter than 1 6O\, with range values between 5 and 30 cm\, approximately\; the absolute depth uncertainty reported was 0.2 mm. In our first set of Geant4 simulati ons\, including proton and helium ion beams only\, we have obtained a prel iminary water I-value of 78.1(5) eV [9]\, which is compatible with the cur rent I-value recommended by the ICRU\, 78(1) eV.\n\nA second Monte Carlo a ctivity is focused on the radiobiological description of proton beams\, bo th macroscopically and microscopically. As for macroscopic description of the radiation quality\, we have come up with a more reliable strategy to c alculate dose-average LET (LETd) distributions in voxelized geometries\, s ince we showed that the most popular scoring approach is subject to bias [ 10]. This is of importance as for the use of phenomenological radiobiology models found in the literature [11-13]. As for microscopic approach\, we are currently producing a set of distributions of microdosimetric stochast ic quantities\, such as lineal energy (y) and collisional energy imparted (εc)\, to characterize the radiation quality of the proton beam [14]. We also plan to verify the limits of applicability of a relation proposed by Kellerer between the macroscopic LETd and dose-mean lineal energy (yD) [15 ]. Finally\, our ultimate aim is to compare our calculations with experime ntal measurements\, both at Centro Nacional de Aceleradores (CNA\, Seville ) and proton therapy centers.\n\nThis work was funded in part by the Spani sh Ministry of Economy\, Industry and Competitiveness (under projects no.

The Monte Carlo simulations were perform ed at our computing cluster FIS-ATOM\, hosted at Centro Informático y Cie ntífico de Andalucía (CICA\, Seville\, Spain)\, whose staff support we g ratefully appreciate.\n\nReferences\n\n[1] PTCOG web page: https://www.ptc og.ch/\n[2] H.

In particular\, the possibility to\nimplement chiral\, topo logically protected edge states analogous to those found in the context of \nquantum Hall physics has been demonstrated both for fermionic and bosoni c atoms [2\,3].\nIn this work\, we propose an alternative strategy to impl ement robust edgelike states (ELS) in\noptical ribbons\, which we model by regarding each of the sites as a two-dimensional harmonic trap\nof equal frequency\, with a single atom carrying l = 0 or l = 1 orbital angular mom entum (OAM)\nunits. First\, we consider a system of three in-line sites go verned by tunneling dynamics\, which can\nbe described by a few-state mode l. We show that in this system quantum interference effects give\nrise to spatial dark states (SDS)\, i.e.\, states in which one site remains unpopu lated along the time\nevolution. Then\, we show that by using the SDS as b asic building blocks\, global ELS can be created\nin arbitrarily large rib bons. These ELS are very robust against defects in the ribbon and\nperturb ations in the phase differences between the local eigenstates of the sites required to have\nquantum interference [3].\nFor the l = 0 case\, the tun neling amplitudes between sites are always real and interference\neffects are solely induced by phase differences between the populated sites. This fact allows one to\ncreate ELS within this manifold and switch between the m in a very straightforward manner by\napplying laser pulses\, as shown in the left panel of figure 1\, and also opening the possibility to\nimpleme nt similar ELS in more complex geometries.\nFor the l = 1 case\, the few-s tate description is richer because the tunneling amplitudes depend\nboth o n the spatial localization and the winding number of the local states\, an d they may become\ncomplex depending on the relative position of the sites [4]. The ELS implemented in this manifold\ncan display global chirality\, as shown in the right panel of figure 1. Another interesting possibility\ nthat this manifold offers is to simulate an extra dimension by regarding the winding number as a\nsynthetic dimension.\n\nhttps://indico.ific.uv.es /event/2851/contributions/4371/ LOCATION:Facultad Química (USC) Aula Química General URL:https://indico.ific.uv.es/event/2851/contributions/4371/ END:VEVENT BEGIN:VEVENT SUMMARY:Variabilidad de las propiedades físicas y su influencia en el eco sistema de la plataforma continental de A Coruña.

Universidad Católica San Antonio Murcia)\nIntroducción\nEl Hospital Q uirónsalud Torrevieja cuenta desde el año 2004 con un acelerador lineal de electrones móvil MOBETRON para uso específico en radioterapia intraop eratoria (RIO). Este acelerador móvil no necesita de una sala blindada\, ni de una infraestructura específica [1]\, por lo que está situado en un o de los quirófanos del hospital. De esta forma se puede tratar el lecho quirúrgico de los pacientes evitando el traslado de los mismos a un búnk er de radioterapia convencional. Una de las ventajas de la RIO es que se p uede evitar\, en una única sesión\, y dependiendo de la lesión\, un tra tamiento posterior de radioterapia convencional que puede alargarse hasta cinco semanas. Esto es posible para cualquier localización del tumor\, en especial en el tratamiento del cáncer de mama.\nTras una parada prolonga da se ha requerido de una nueva puesta en marcha del equipo en la que hemo s estudiado la alteración de los diferentes parámetros dosimétricos.\n\ nMaterial y Método\nEl acelerador móvil de electrones sobre el que se ha trabajado es un MOBETRON de la serie 1000 [2]\, de la firma IntraOp Medic al Corp. Para su puesta en marcha se ha contado con la ayuda de los ingeni eros de esta misma firma\, la cual se encargó de su diseño\, fabricació n e instalación.\nEl acelerador cuenta con cuatro energías nominales dis ponibles\, de 4\, 6\, 9 y 12 MeV [3]. Y con una tasa de dosis máxima de 1 000 UM/min. Tras una revisión pormenorizada de los circuitos de refrigera ción y vacío se verificó por parte del fabricante el ajuste del haz de radiación y la tasa de dosis estable de funcionamiento conseguida para ca da energía. Se analizó la constancia de dosis y energía con el sistema de control de calidad de que dispone el acelerador\, en los rangos Rmáx y R50\, con un conjunto cámara farmer 30013 y un electrómetro UNIDOS E de PTW. Se realizaron medidas en agua de los rendimientos de dosis en profun didad y de los perfiles de dosis a la profundidad del máximo\, con cuba M P3 de PTW y diodos Scanditronix y Wellhofer AB\, caracterizando la simetr ía [4] y homogeneidad de cada una de las energías. Por último y en mani quí de agua plástica se midió la dosis absoluta con cámara plano-paral ela ROOS y se establecieron nuevas dosis de referencia.\n \nResultados\nPa ra la energía de 4 MeV\, no ha sido posible establecer un ajuste que perm itiese un funcionamiento estable a tasas cercanas a la de uso clínico de 1000 UM/min. Dado que este ajuste hubiese comprometído al resto de energ ías y como además esta energía carece de interés clínico (sólo ha si do utilizada en un paciente desde el comienzo de actividades) se ha optado por suspender su uso. Para el resto de energías si ha sido posible estab lecer ajustes estables de funcionamiento del haz con tasas próximas a 100 0 UM/min.\nEn cuanto a la energía\, sólo ha sido necesario hacer un lige ro ajuste de la de 9 MeV. Tanto los haces de 6 MeV como los de 12 MeV se h an mantenido estables respecto a los establecidos antes de la parada.\nRes pecto a la constancia de dosis en los rangos Rmáx y R50 se observó que s e mantenía constante\, con ligeras desviaciones respecto de las medidas d e referencia de que se disponía antes de la parada del equipo.\nSe compro bó que tanto la simetría como la homogeneidad que presentaban los perfil es a la profundidad de máxima dosis absorbida\, estaban dentro de toleran cias\, quedando pendiente una posterior verificación mediante placa radio gráfica.\nLos nuevos valores de dosis de referencia obtenidos mediante do simetría absoluta con maniquí de agua plástica\, están en concordancia con los establecidos en el estado de referencia previo a la parada del eq uipo.\n\nConclusiones\nSe ha logrado poner en marcha el acelerador móvil MOBETRON después de un periodo de parada muy largo (superior a 3 años). La intervención del fabricante para esta puesta en marcha ha sido menor d e lo previsible inicialmente. La estabilidad del equipo desde el punto de vista dosimétrico ha sido muy buena requiriendo tan sólo un ligero ajust e de energía para el haz de 9 MeV\, restituyendo el equipo a su estado de referencia previo a la parada. De hecho la dosis de referencia ha permane cido constante respecto a los valores registrados previos a la parada del equipo y en concordancia con los valores de constancia establecidos en la literatura [4].\n\nAgradecimientos\nExpresar nuestro agradecimiento a Intr aOp Medical Corp.

Particular attention is addressed to range\, strength and anisotropy of non-covalent interaction components\, due to the balance of size (or Pa uli) repulsion with dispersion and induction attraction\, to which must be added electrostatic contributions\, and of other components of covalent ( chemical) nature\, mostly affected by charge (electron) transfer effects. The analysis of several experimental findings has been important to develo p suitable analytical representations of the potential energy surfaces (PE Ss)\, tested and improved by exploiting also the comparison with results o f ab initio calculations\, useful to provide an internally consistent desc ription of the intermolecular interaction both in the most and less stable configurations of the interacting system.

Estas simulaciones pu eden versar sobre contenidos relevantes del currículum de Física en Secu ndaria y en Bachillerato [2].\n\nEn este sentido\, una posibilidad muy int eresante\, pero de momento poco explotada\, es la de realizar experimentos \, en los que se estudie la concordancia entre el fenómeno físico invest igado y una simulación del mismo\, creada por el docente o por los propio s alumnos con este programa. Se trata de un recurso muy útil para el aná lisis experimental y no sólo puede complementar muy bien a otros recursos (por ejemplo\, el uso de sensores de magnitudes)\, sino que\, en algunas ocasiones\, puede salir en auxilio del investigador\, cuando aquellos no s on utilizables.\n\nListado resumido de experimentos\n\nHemos realizado\, h asta el momento\, 16 experimentos (y sus variantes) de física\, que lleva ron a cabo grupos de estudiantes de varios institutos. Todos ellos están disponibles en Internet [3]\, donde se accede a una descripción de cada u no y se pueden descargar las animaciones resultantes tras los análisis ex perimentales. En la tabla nos referimos escuetamente a 9 de ellos.\n\n(La tabla con los 16 experimentos comentados puede verse en el documento que s e adjunta)\n\nComentarios sobre dos de los experimentos\n\nEn la ponencia mostraremos varios análisis experimentales con cierto detalle\, manipulan do las correspondientes simulaciones. Veamos aquí un breve comentario sob re dos de ellos. \n\nTiro oblicuo: Ejemplo de movimiento\, cuyas posicione s no se pueden medir con el sensor. Para crear la animación (Fig. 1) usam os una filmación sobre un tiro libre en un partido de baloncesto. El aná lisis experimental permite verificar\, en primer lugar\, la hipótesis de Galileo de descomposición del movimiento oblicuo de la pelota en un movim iento horizontal (uniforme) y otro vertical (uniformemente acelerado). Los alumnos le imponen a la pelotita virtual que cumpla las leyes escritas ba jo dicha hipótesis\, y comprueban que se sitúa en todo instante sobre la pelota real. Usando los valores conocidos de las dimensiones de la cancha de baloncesto\, los alumnos también traducen las ecuaciones de pixels a m y así verifican que la aceleración vertical de la pelota es igual a g. \n\n(La figura 1 puede verse en el documento que se adjunta)\n\nRodadura p or un plano horizontal: Ejemplo de experimento “doble”\, en el que p rimero se usan sensores de magnitudes y luego se utiliza el simulador (cua ndo los alumnos toman medidas del movimiento con el sensor de posición ta mbién lo filman). El primer análisis realizado con el software de los se nsores permite obtener tablas y gráficas sobre la evolución de las magni tudes cinemáticas (posición\, velocidad y aceleración)\, y deducir a pa rtir de estos datos otras magnitudes\, como la fuerza de rozamiento por ro dadura que va frenando al carrito hasta detenerlo. En la segunda parte del experimento\, se construye una animación Modellus\, sobre la que se vuel ca el clip de video del movimiento\, para compararlo con una simulación d el mismo que obedece a las leyes de Newton. La animación resultante (Fig. 2) permite verificar no sólo la aplicación de dichas leyes al propio mo vimiento (una vez hecho el cambio de escala\, la partícula virtual queda siempre sobre el punto central del carrito filmado)\, sino también a sus gráficas (las gráficas del movimiento virtual también se van dibujando exactamente encima de las obtenidas con los sensores)\n\n(La Figura 2 pued e verse en el documento que se adjunta)\n\nConclusiones\n\nLa comparación entre el proceso real y una simulación del mismo que obedece las leyes d e la Física es una técnica potente y\, a la vez\, bastante sencilla para la realización de algunos experimentos en el Instituto. Los 16 experimen tos que hemos desarrollado hasta ahora se han podido incardinar en los cur rículos de Física en Secundaria y en Bachillerato\, y también se han di fundido con muy buena acogida en cursos de formación docente. \n\nReferen cias\n[1] http://modellus.co/index.php?lang=es\n[2] M.

Damián Domínguez Muñoz (Universidad de Sevilla )\nIntroducción\nLas técnicas en radioterapia están en continua evoluci ón. Su objetivo es conseguir una distribución de dosis tal que sea máxi ma en la zona tumoral y mínima en el tejido sano para evitar efectos secu ndarios no deseados. El desarrollo de técnicas avanzadas en radioterapia conlleva una mayor complejidad en los tratamientos\, lo que hace necesario un desarrollo paralelo de técnicas de verificación dosimétricas. En es te trabajo se presenta un novedoso método de reconstrucción de mapa de d osis a partir de la información obtenida por un detector prototipo de tip o semiconductor de tiras de silicio que implica una serie de mejoras sobre el método usado originalmente [1].\nCaracterísticas del detector. Monta je experimental.\nEl prototipo está compuesto por dos detectores de tiras de silicio (en inglés single-sided silicon strip detector SSSSD) de gros or 500μm separados por 500μm de Kapton. Cada detector está dividido en 32 tiras de anchura 2mm y longitud 64mm\, rotado uno respecto al otro un ángulo de 90º [2]. Se inserta en el centro de un maniquí cilíndrico de polietileno (de dimensiones típicas de una cabeza) de manera que el plan o que define el detector es perpendicular al eje de simetría del cilindro . En general en esta disposición el detector será paralelo a la direcci ón de los haces de tratamiento. Las medidas corresponderán al plano axia l del paciente\, que es el plano usado de forma habitual en las imágenes utilizadas en la práctica clínica para especificar la distribución de l a dosis que debe recibir el paciente en su tratamiento. Es por tanto el m ás indicado para realizar la verificación del mismo.\nEn cada franja del detector se colecta la carga liberada por la radiación\, que será propo rcional a la dosis depositada por la misma en esa área. Una medida corres pondiente al detector girado un cierto ángulo respecto a una posición de referencia proporcionará la dosis media en cada tira en esa posición an gular. De esta manera\, para reconstruir el mapa de dosis completo es nece sario tomar medidas en varias posiciones angulares. Gracias a la forma de los dos detectores y que las tiras de ambas forman un ángulo relativo de 90º\, para la reconstrucción del mapa de dosis sólo será necesario gir ar el detector entre 0º y 90º\, lo cual reduce el tiempo necesario para la obtención de los datos experimentales para realizar la verificación.\ nReconstrucción del mapa de dosis\nEn general\, los métodos de reconstru cción consisten en obtener una cierta distribución φ a partir de una di stribución conocida experimentalmente Φ\, siendo conocida también la fu nción que proyecta la primera en la segunda\, es decir\, Φ = f(φ). Los métodos de resolución pueden clasificarse en dos grupos: métodos analí ticos y métodos iterativos. \nLos métodos analíticos consisten en halla r la función de proyección inversa. Mediante la transformada de Fourier es posible el planteamiento y la resolución del problema en el espacio re cíproco\, lo que permite el uso de filtros\, tratándose así de métodos de retroproyección filtrada. \nLos métodos iterativos realizan la recon strucción mediante un bucle cerrado de operaciones. En cada iteración se parte de una distribución dada φo\, se proyecta según fobteniéndose Φo y\, comparando la proyección obtenida con la experimental Φ\, se obt iene una nueva distribución inicial corregida que será el punto de parti da de la siguiente iteración. En todo método de iteración están presen tes el paso de proyección\, que viene definido según el problema físico que se esté tratando\, y el paso de comparación-actualización\, que no está específicamente determinado pero su elección debería estar funda mentada en modelos relacionados con el sistema de detección para tener un a convergencia rápida de la distribución hacia la solución final.\nEn e l método analítico\, la reconstrucción del mapa de dosis se realiza de forma directa a partir de los datos experimentales [1]. De esta manera\, l a calidad de la reconstrucción está limitada a la cantidad de informaci ón experimental de la que se dispone. Para el detector a tiras\, el tama ño mínimo del pixel vendrá dado por el número de posiciones angulares en las que se han tomado medidas. Por otro lado\, el posible fallo en la l ectura de alguna tira y por tanto el desconocimiento de la dosis asociada\ , puede dar lugar a huecos en la reconstrucción del mapa. Además el inte rés clínico requiere que la planificación y verificación de los tratam ientos sea lo más rápida posible para agilizar las intervenciones de los pacientes. En este sentido hay que minimizar el tiempo de toma de datos\, por lo que la dependencia directa de este tipo de método con las medidas hace necesaria la búsqueda de métodos alternativos.\nLos métodos itera tivos\, aunque son comúnmente usados para la reconstrucción de imagen pa ra diagnóstico en el campo de la medicina nuclear\, suponen una novedosa técnica en la reconstrucción de mapa de dosis para verificación en el c ampo de la radioterapia. En este tipo de métodos\, los datos experimental es sirven para comparar la proyección de una distribución de partida y c orregirla. Como la proyección viene dada por el propio problema físico\, puede definirse siempre independientemente de las características con la s que se desee reconstruir el mapa de dosis. De esta manera\, es posible r ealizar una reconstrucción completa con una menor dependencia de la canti dad de información que se disponga\, además de tener flexibilidad en la forma que la que se realiza la comparación y la corrección.\nSe muestra un ejemplo de reconstrucción usando el método iterativo (figuras 1b y 1c )\, a partir de los datos obtenidos con el prototipo descrito anteriorment e en el Hospital Universitario Virgen Macarena de Sevilla para un determin ado tratamiento. El paso de proyección está relacionado con la contribuc ión de cada pixel a cada tira en cada posición angular. El paso de compa ración y actualización se obtiene con métodos de estimación de máxima verosimilitud con una distribución de Poisson para el ruido estadístico [3 y sus referencias]. Este mapa de dosis se compara con el obtenido con el planificador (figura 1a).\n\nReferencias\n[1] M. I. Gallardo et al (201 4). “Sistema y método de verificación de tratamientos de radioterapia ”.

It is crucial for understanding different processes and character istics of nuclei such us superfluidity. We can easily found clear situatio ns where neutrons form strongly correlated pairs with total angular moment um J=0 and isospin T=1. This produces a strong enhancement of two-neutron transfer reactions\, thus being the main probe to test correlations. In N= Z nuclei one would expect to observe also a strong correlation between neu trons and protons. Here\, we can find isovector pairs with J=0\; T=1 but a lso isoscalar ones with J=1\; T=0. However\, the existence and magnitude o f pn isoscalar pairing is still under debate. Many experiments on np trans fer have been made along the N=Z line but very few performed and analyzed systematically along a major shell.\nIn this contribution\, we analyze (p\ ,3He) and (3He\,p) transfer reactions in N=Z sd-shell nuclei. The exclusiv e cross sections to the lowest 0+ and 1+ states in the odd-odd N=Z nuclei were populated in a series of experiments performed at Grand Raiden high-r esolution spectrometer at the RCNP of the Osaka University. These data wil l be compared to 2nd-order DWBA calculations with proton-neutron amplitude s obtained in the Shell Model formalism by using USDB interaction.\nThe pr eliminary analysis shows tentative cases where the pn isoscalar pairing is not negligible and need to be taken into account in order to reproduce th e present experimental data.\n\nhttps://indico.ific.uv.es/event/2851/contr ibutions/4352/ LOCATION:Facultade de Química (USC) Aula Química Física URL:https://indico.ific.uv.es/event/2851/contributions/4352/ END:VEVENT BEGIN:VEVENT SUMMARY:Testing macroscopic realism with measurements of light polarizatio n DTSTART;VALUE=DATE-TIME:20170719T160500Z DTEND;VALUE=DATE-TIME:20170719T162500Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4351@indico.ific.uv.es DESCRIPTION:Speakers: Eugenio Roldán Serrano (Universitat de València)\n We study Leggett-Garg inequalities and no-signaling in time to determine t he macrorealistic character of light polarization.

The EChL Lagrangian is used as an intermediate energy approximation (E~500 GeV)\, where the Equivalence Theorem is valid but the EFT does not violate unitarity.\n\nOf highest interest is the EWSBS and the description of the scattering processes between longitudinally polarized gauge bosons and the Higgs-like particle discovered at the LHC. Because ttbar channel is more accessible at the LHC\, we couple such processes with ttbar. Hence \, we use the A[W_L\,Z_L\,h-->W_L\,Z_L\,h] scattering amplitudes computed at NLO\, and consider a weak (perturbative) coupling with ttbar states\, i n order to compute the A[W_L\,Z_L\,h-->t tbar] scattering amplitudes.\n\nU nitarization procedures are used to extend the validity range of the EFT u p to the first resonance\, where the EFT perturbative expansion breaks dow n.

Experimentally it has been possible to inser t atoms and molecules within molecular\nnanocavities. This brings the poss ibility of employing such as novel structures for different\napplications\ , ranging from energy storage and transport to medical use. In addition\, depending on\nthe relative sizes\, confinement may exert a strong influenc e on the electronic structure of the guest\natom or molecule. This opens u p the field for manipulating the spectroscopic properties of the\nconfined atom\, which is of great interest in optics and electronics.\n\n\n I n this work we focus in the stability of the atom after it is released fro m the cavity. If the\nconfined atom or molecule is stored in order to be u sed to produce energy or to be transported\, it is\nimportant to analyze i f the atom is stable when the confining environment is removed.\n Her e we consider the H atom within an impenetrable spherical wall. This simpl e model\nreproduces the most important physical features of confinement an d the study of the H atom\nsimplifies the computational problem and the po ssible excitation mechanisms after the system is\nreleased. The excited st ates of the H atom\, both in the discrete and the continuous spectra can b e\nobtained very accurately.\n We assume that the atom is liberated i n a period of time that can be considered small as\ncompared with the dyna mics of the atom. Then the sudden approximation can be employed to study\n the state of the atom after confinement is removed. Within this approach\, the time dependent state\nof the released atom after is expanded in terms of the stationary states of the free Hamiltonian. In\nthis expansion both \, the bound states and the Coulomb wave functions need to be included. Th e\nlinear coefficients provide the amplitude probability of the released a tom to reach the corresponding\nstationary state of the unconfined atom. T he values of these coefficients are calculated as the\noverlap of the conf ined wave function with the wave function of the unconfined atom.\n\n\n In Table 1 we show the energy of the three stationary states of the H at om here studied. We\nconsider hard wall spherical confinement of radius 2 au with the nucleus of the atom fixed at the\ncenter of the wall.\n\n\n In Figure 1 we plot the ionization probability energy distribution of the atom when\nconfinement is released.\n\n In all of the cases shown\, a spread distribution around a principal maximum is obtained. The\nvalue of the energy at the maximum is close and smaller thant the energy of the co nfined state. The\nother secondary maxima\, obtained at higher energies\, are less important. The probability\ndistribution presents several nodes\, showing that no electrons with that value of the energy can be\nemitted.\ n\n Financial support from the Spanish DGICYT and FEDER\, project num ber FIS2015-69941-C2-\n2P\, and from the Junta de Andalucía (FQM378) and Universidad de Córdoba is gratefully\nacknowledged.\n\nReferences\n\n[1] K.

The ‘energy transformation’ is surely one of \nthe most important challenges of the 21st century. Correct planni ng and thorough insight into the complexities of energy systems are an absolute necessity before starting such a task\, in order to avoid unnecessary disruptions in the economy and daily l ife of the citizens. \nThe European Union has ambitious plans n t his direction for the coming decades. \nHowever\, there is no simple answer to the best way forward. In the electricity sector emphasis is currently put on massive developments in renewable systems (wind\, \ nsolar\, hydro\, biomass\,…). As wind and solar are main com ponents\, the consequences of the intermittency need to be ful ly understood. Important components for a green \nelectricity system dominated by intermittent sources are still lacking and developing these is challenging and will take time. Therefore it is not justified to eliminate any of the non-renewable options i n near future and future electricity \npolicies.\nThe plans of the EU need also to be shaped in the context of worldwide greenhouse g as emissions and estimated future world energy needs. The effectiv eness of green electricity policies implemented in the EU so far will be discussed using the example of the Germany.\nA last but very important remark is about the information for the g eneral public.\nUnfortunately\, the quality of public and political dis cussions on this subject is a matter of great concern\, as the se frequently lack reference to realistic numbers\, or use numbers very selectively. Even worse\, critical discussions are very often simply ignored or rebuffed with unfounded black and white a rguments. Given the importance of sufficient and high quality energy sources for the welfare of all citizens on this planet in the future\, there is an important role for education. This should be an important asset in order to arrive at a correct ly defined and affordable\nsustainable future energy supply.\n\nhttps:/ /indico.ific.uv.es/event/2851/contributions/4339/ LOCATION:Santiago de Compostela\, Facultade de Química Aula Magna URL:https://indico.ific.uv.es/event/2851/contributions/4339/ END:VEVENT BEGIN:VEVENT SUMMARY:WORKSHOP ALTA INTEGRACIÓN DE RENOVABLES EN SISTEMA ELECTRICO.

Nature has developed highly specialized molecular building blocks capable of transporting charge with unprecedented efficiency\, i.e. fast and at long distances [2]. Understand ing the mechanisms behind biological ET is key to elucidate the changes in the charge transport regime caused by specific structural variations of t he associated molecular machinery\, which ultimately lead to\, for instanc e\, malfunctioning of the mitochondria. Fundamental knowledge gained from studying biological ET can also be exploited to design bioelectronic devic es. Such studies would ultimately unveil what are the key parameters to be controlled in the transduction of electrical signals from active biomolec ules\, and direct us to the design of the next generation of highly specif ic optoelectronic sensors [3]. In order to comply with the downsizing dema nds of the microelectronics industry\, the latest bioelectronic advances f ocus on bottom-up perspectives [3]\, aiming for maximum sensitivities\, hi gh signal-to-noise ratios and enhanced efficiency in order to reduce energ y consumption.\nModel redox proteins have been integrated in nano/micro-sc ale devices as the charge transport material. Cu-Azurin conductance signat ures have been recently observed in microscale solid-state devices [4-6]\, which demonstrates their compatibility when hybridized to an electronic p latform. Furthermore\, Cu-Azurin and cytochrome b562 have also been extens ively analysed at the single-protein level [7\,8]. These pioneering studie s established the sequential two-step ET tunneling mechanism for such syst ems26\, and demonstrated the feasibility of such hybrid bio-interfaces to work as active components in nanoscale circuits.\nHere [9] we present an e xample of bioengineering charge transport in a single-protein wire. The co pper-binding protein Azurin has been exploited to compare charge transport of single-protein devices made of a wild-type (Wt) structure and a mutant (K41C)\, where\, in the latter\, the natural lysine (Lys) 41 residue has been replaced by a cysteine (Cys) (Fig. 1a). This single point mutation ha s a two-fold effect\; first\, the new solvent-exposed thiol (-SH) group wi ll serve as a new chemical connection to one of the external device termin als\, and second\, the modification is in the secondary coordination spher e of the Cu centre\, which is expected to influence the metal redox behavi or [10\,11] and\, hence\, the transport regime through the protein matrix. Individual proteins of both variants were trapped between two metal elect rodes in a physiological environment using an Electrochemical Scanning Tun neling Microscope (EC-STM) configuration\, and the charge transport charac terized as a function of an applied electrochemical gate voltage and tempe rature [12\,13]. All-atom molecular-dynamics (MD) simulations suggest that the electrode-protein-electrode junction occurs via two well-localized si tes on the protein\, i.e. the hydrophobic patch and the natural Cys residu es. Despite comparable orientations of both Wt and K41C proteins bridges a re expected\, the results show acute differences in the charge transport m echanism of the single-protein wire between the Wt and the mutant variant\ , observing in the latter a complete shutdown of the two-step sequential t unneling character typically described in the Wt [26]. Ab initio calculati ons of the relevant ET pathway fragment including the modified residue 41 show the poor participation of the Cu centre in the transport-relevant mol ecular frontier orbital of the K41C mutant. These results fully account fo r the observed conduction changes within the framework of coherent tunneli ng mechanism for the single-protein wire of bioengineered proteins.\n\n[1] E.

Algunas veces aparecen en estas fuentes de datos métodos de medici ón que a primera vista parecen desfasados e inútiles y a los cuales no s e les da una oportunidad. Es en este trabajo donde desde la recuperación de datos pasamos a la recreación del método. En este trabajo presentamos una metodología para recrear uno de los primeros sistemas de medición d e ozono diseñados en el S. XIX y verificamos la validez de las mediciones realizadas con él.\nRecuperación de datos\nPrimero presentamos las seri es meteorológicas de finales del siglo XIX y principios del siglo XX loca lizadas en el observatorio de A Guarda\, pionero en Galicia en este tipo d e medidas y localizadas en ese tiempo en el “Colexio Xesuita Apóstol Sa ntiago”. Las series de datos obtenidas fueron obtenidas de las notas met eorológicas publicadas en el periódico católico “La Integridad”\, p ublicado en esas fechas en Tui (Galicia). Fueron revisados más de 1000 pe riódicos de esta publicación y fueron digitalizados\, manualmente\, más del 60000 medidas individuales. Aparte de las medidas anteriormente menci onadas en el periódico también aparecían previsiones meteorológicas ba jo el nombre de “El Tiempo”. \nAñadimos también la verificación e i nterpretación de estos datos\, (incluyendo los ciclos intraanuales). Esta validación se realizó a través de tres distintas bases de datos\, incl uyéndose también el análisis hecho [1]. \nRecreación del método\n Tras localizar datos de mediciones de ozono troposférico en las notas met eorológicas investigamos sobre el método usado y llegamos a la conclusi ón de que habría que revisar el método\, ya que toda referencia bibliog ráfica tiene más de 30 años\, aparte de que sufrió una demonización a lo largo del siglo XX a pesar de ser el más extendido y usado[2]. Buscam os las fuentes bibliográficas originales y recreamos el método tal cual se hacía en el siglo XIX. Se realizó una campaña de medición en condic iones de atmósfera libre para determinar si este método medía o no vari aciones de ozono. \nSe presentaran las conclusiones obtenidas durante toda la campaña\, conteniendo también los problemas confrontados en las campañas de medición y trabajo de campo. \nReferences\n[1] Añel J.A.\, et al.\, Weather (2017)\n[2] Bokjov R.D.\, J.

First suggest ed by D. Brogioli\, it is enclosed in a group of emergent technologies joi ntly known as Capmix methods. The CDLE technique is based on the fact that the capacitance of the electric double layer (EDL) strongly depends on th e ionic contents of the medium. If a metal/solution interface is externall y charged in the presence of high ionic strength\, and discharged in low i onic strength\, it might be possible to obtain a net amount of energy. In order to increase the charge transfer\, electrodes made of micro- or nano- porous carbon particles can be used because of their huge surface area.\nT he behaviour of the fluid flow field\, the electric potential field and th e ionic distributions inside the nanopores during an entire CDLE cycle mus t be correctly determined to gain a complete understanding of the physics involved and to optimize the energy extraction per cycle. We have performe d a finite element analysis that computes the time-dependent full coupling between the Navier-Stokes\, the Poisson and the mass transport (diffusion \, convection and electromigration of ions) equations. From the numerical solutions\, we have been able to obtain the relevant time scales of the pr ocesses that take place inside the nanopores and to compare them with expe rimental results.\nAs an example\, the figure shows the time evolution of the ionic sodium concentration in a representative pore just after exchang ing the solution in contact with the pore mouth from sea water to river wa ter. Note that the expansion of the EDL has started in the region close to the mouth of the nanopore and that it is extending towards its interior.\ n\nhttps://indico.ific.uv.es/event/2851/contributions/4324/ LOCATION:Facultad de Química (USC) Aula Física URL:https://indico.ific.uv.es/event/2851/contributions/4324/ END:VEVENT BEGIN:VEVENT SUMMARY:MESA REDONDA.

They scatter Cooper pairs as a potential with broken time- reversal symmetry\, what leads to localized bound states (usually refered as Shiba states) with subgap excitation energies. These states\, first pre dicted by Yu\, Shiba\, and Rusinov [1]\, are identified in scanning tunnel ing spectra as pairs of intra-gap resonances symmetrically positioned arou nd zero-bias. \nMost conventional approaches to study Shiba states treat m agnetic impurities as point scatterers with an isotropic exchange interact ion\, while the complex internal structure of magnetic impurities is usual ly neglected. Due to the orbital character of the scattering channels of the impurities\, it is expected that Shiba multiplets reflect the occupati on level of the atomic shell\, what would render them as the ideal probe f or identifying the magnetic ground state of a single impurity in a superco nductor. \nIn this presentation\, I will show high-resolution scanning tu nneling spectroscopy measurements and Density Functional Theory simulatio ns\, which provide evidence that that the number and shape of Shiba stat es are correlated to the spin-polarized atomic orbitals of the impurity\, hybridized with the superconducting host. We investigated Cr impurities on Pb(111) [2] and spatially map the five Shiba excitations found inside the superconducting gap\, resolving both their particle and hole components. While the maps of particle components resemble the d orbitals of embedd ed Cr atoms\, the hole components differ strongly from them.

LHCb is a forward spectrometer whose acce ptance and specific features makes it very complementary to the rest of th e LHC experiments. \nLHCb has been able to produce many interesting measur ements so far that have turned out to be very important to understand the composition and nature of matter at the most elemental scales. Examples of very well known results concerning flavor physics and spectroscopy are th e first observation of the Bs→μμ decay [1]\, the measurement of the CP -violating phase ϕs [2] or the observation of J/ψp resonances consistent with pentaquark states [3].\nHowever\, in the last years\, LHCb has been able to make relevant contributions in many other areas beyond those for w hich it was originally designed\, a summary of which will be presented in this talk. More specifically\, focus will be set on newest results and in those areas in which the author has worked more actively. These and many o ther results make LHCb currently a general purpose detector in the forward region.\n\n- Direct searches for light particles\nSeveral New Physics (NP ) models predict the existence of particles beyond those of the Standard M odel (SM) for whose detection LHCb is particularly well suited. The main r eason for this is a flexible trigger\, significantly softer than those of ATLAS and CMS\, and the presence of unique detectors\, such as RICH\, whic h is able to provide a measurement of the mass of long lived charged parti cles. Among others\, LHCb has searched for displaced particles decaying to jets [4] or semi-leptonically [5] as well as long-lived heavy charged par ticles [6]. Although no evidence for new particles has been found\, these results are useful to constraint the parameter space of several NP models. \n\n- Standard Model physics\nThe SM is currently our best approach to exp lain the dynamics and behavior of particles at the subatomic level. The LH Cb detector allows performing several measurements to test the precision o f the SM\, in some cases to an unprecedented level at a hadron collider. I n this regard\, the LHCb measurements are very useful to constrain the int ernal structure of the proton measuring the Z production in the forward re gion [7] or to probe hard QCD in a unique environment\, providing the firs t evidence for certain processes\, such as W+cc [8]. Furthermore\, LHCb is expected to make relevant contributions to Higgs physics in the mid-term. On this subject\, a first search for the decays H→bb or cc\, with the H iggs produced in association with a W or Z boson has already been performe d [9].\n\n- Physics with heavy ions\nLHCb was not initially conceived for heavy ion physics. However\, following the excellent performance of the de tector and the increasing interest in this area at LHCb\, data has been re corded in different configurations\, including Pb-Pb\, p-Pb and Pb-p colli sions. Furthermore\, LHCb can be turned into a fixed target experiment by injecting noble gases in the collision region. These special configuration s can be very useful from a physics point of view. A remarkable example is that of the measurement of the anti-production in p-He collisions [10]. T he production ratio between protons and anti-protons has been measured by several astroparticle experiments since it is a sensitive probe to dark ma tter in the Universe. Given that the dominant uncertainty to better unders tand this ratio comes from the anti-proton production\, the measurement of the anti-proton production cross section in p-He collisions is crucial an d becomes an excellent example of the contributions that LHCb can make in this regard. \n\n- References\n[1] LHCb Collaboration\, Observation of the rare Bs→μμ decay from the combined analysis of CMS and LHCb data\; Na ture 522\, 68-72 (2015).\n[2] LHCb Collaboration\, Measurement of the CP-v iolating phase ϕs in the decay Bs→J/ψϕ\; PRL 108\, 101803 (2012).\n[3 ] LHCb Collaboration\, Observation of J/ψp resonances consistent with pen taquark states in Λb→J/ψKp decays\; PRL 115\, 072001 (2015).\n[4] LHCb Collaboration\, Search for long-lived particles decaying to jet pairs wit h the LHCb Run 1 data (to appear as LHCb-PAPER-2016-065).\n[5] LHCb Collab oration\, Search for massive long-lived particles decaying semileptonicall y in the LHCb detector\; EPJC (2017) 77: 224 \n[6] LHCb Collaboration\, Search for long-lived heavy charged particles using a ring imaging Cheren kov technique at LHCb\; EPJC 75 (2015) 595.\n[7] LHCb Collaboration\, Meas urement of the forward Z boson production cross-section in pp collisions a t √s = 13 TeV\; JHEP 09 (2016) 136.\n[8] LHCb Collaboration\, Measureme nt of forward tt\, W+bb and W+cc production in pp collisions at √s = 8 T eV\; PLB767 (2017) 110.\n[9] LHCb Collaboration\, Search for H→bb or cc in association with a W or Z boson in the forward region of pp collisions\ ; LHCb-CONF-2016-006\n[10] LHCb Collaboration\, Measurement of antiproton production in pHe collisions at √sNN = 110 GeV (to appear as LHCb-CONF-2 017-002).\n\nhttps://indico.ific.uv.es/event/2851/contributions/4305/ LOCATION:Facultad de Química (USC) Aula Química Técnica URL:https://indico.ific.uv.es/event/2851/contributions/4305/ END:VEVENT BEGIN:VEVENT SUMMARY:Proton minibeam radiation therapy widens the therapeutic window fo r radioresistant tumors DTSTART;VALUE=DATE-TIME:20170718T151500Z DTEND;VALUE=DATE-TIME:20170718T153500Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4299@indico.ific.uv.es DESCRIPTION:Speakers: yolanda prezado (IMNC-CNRS)\nRadiotherapy (RT) has a key role in cancer treatment. In fact\, about half of the patients will r eceive RT at some point during their illness. Despite remarkable advanceme nts in RT over the last two decades\, significant limitations remain: the tolerance of surrounding normal tissues constitutes a ceiling on tumour do ses. In consequence\, the treatment of some radioresistant tumours (e.g. g liomas)\, tumours close to a sensitive structure (e.g. central nervous sys tem) and paediatric cancers is limited. The main challenge in RT is\, ther efore\, to find novel approaches allowing increasing the normal tissue res istance. Along this line we proposed in 2013 a novel concept: proton minib eam radiation therapy (pMBRT) [1]. It allies the physical advantages of pr otons with the normal tissue preservation observed when irradiated with su bmillimetric spatially fractionated beams (minibeam radiation therapy) [2] . We have recently implemented the technique [3] at a clinical center (Pro ton therapy center in Orsay). The technical developments for minibeam gene ration at a clinical center will be described. The first complete set of d osimetric data in such small proton field sizes was obtained. Due to proto n lateral scattering\, each proton minibeam of the array (“tooth of the comb”) gets wider as a function of the depth\, overlapping at the tumour position. As a consequence\, a homogeneous dose distribution is generated inside the tumour (like in conventional RT)\, while the concept of spatia l fractionation (peaks and valleys) and its advantages are maintained in t he irradiated regions of normal tissue [1]. See Figure 1. In addition\, a negligible dose is deposited in normal tissues after the Bragg peak. \nWe have recently performed a series of in vivo experiments. In the first one the whole brain of 7 weeks old male Fischer 344 rats (n=16) was irradiated with 100 MeV protons. Half of the animals received conventional seamless proton irradiation (25 Gy in one fraction). The other rats were irradiated with pMBRT (58 Gy peak dose in one fraction). The average dose was deposi ted in both cases. The animals were followed up for 7 months. A magnetic resonance imaging (MRI) follow up at a 7T small animal MRI scanner as well as histological analysis were performed. Rats treated with conventional proton irradiation exhibited severe skin and brain damage. In contrast\, the pMBRT group presented neither skin nor significant brain damage.\n\n\ n\n\nThese results indicate that pMBRT leads to an increase in normal tiss ue resistance. This net gain in normal tissue sparing can open the door to an efficient treatment of very radioresistant tumors\, which are currentl y mostly treated palliatively. In a second experiment we have irradiated glioma (RG2) bearing rats with the same average doses. Long-term survivals have been obtained in the pMBRT group indicating tumor ablation without d eleterious side effects. In conclusion\, pMBRT widens the therapeutic wind ow for brain tumors\, potentially offering a curative option for gliomas\, a very aggressive tumor\, for which none efficient treatment exists nowad ays. Additional experiments are planned in order to corroborate this resul t. If confirmed\, it will pave the way to proceed towards clinical trials at Orsay Proton Therapy Center. This novel technique may specially benefit paediatric oncology (central nervous system whose treatments are very lim ited due to the risk of complications in the development of the infants). Furthermore\, pMBRT is predicted to make proton therapy in general more am enable to administration in either a single dose fraction or in a very sma ll number of fractions\, which would significantly reduce the costs.\n\nTh is research was performed with financial support from ITMO Cancer AVIESAN (Alliance Nationale pour les Sciences de la Vie et de la Sante\, National Alliance for Life Sciences and Health) within the framework of the Cancer Plan (2014-2019).

Particularly\, the adoption of a state-to-state level of detail in t he description of the molecular energy transfer [1\,2]\, a desirable and n ecessary improvement\, requires much insight into the dynamics of the inel astic collisions and the prompt availability of state-specific energy tran sfer probabilities and rate coefficients. Existing venerable approximated theories of the energy transfer\, such as the Schwartz-Slawsky-Herzfeld on e\, are not really state-specific and have limited validity. Therefore pro babilities and cross sections have to be calculated directly by simulation of the dynamics of the molecular collisions. The reliability of the simul ations is conditional to the availability of accurate descriptions of the intermolecular interactions occurring between pairs of the molecular speci es present in the gas mixture. Here\, we present examples of calculation o f rate coefficients of energy transfer in mixtures containing CO2 and N2 [ 3-6] obtained applying a semiempirical approach to the interaction modelli ng\, based on (i) a physically meaningful partition of the contribution to the interaction\, (ii) the use of data from molecular beam experiments an d (iii) ab initio calculations.

One of these regards whether we should measure bond st rengths with respect to the ground states of the isolated fragments that b ecome bonded\, leading to standard bond dissociation energies (BDE)\, or i f appropriately "prepared for bonding"\, i.e. excited\, states should be u sed instead. The latter view provides larger bond energies\, which are usu ally called intrinsic bond energies (IBE) [2]. Here we examine this proble m from a real space partitioning point of view\, using the Interacting Qua ntum Atoms (IQA) approach [3] and electron number distribution functions ( EDF) [4]. In IQA\, the molecular energy is exactly written as a sum of ato mic or fragment self-energies and interatomic (or inter-fragment) interact ion energies. The evolution of self-energies along bonding coordinates all ows for the identification of the proper atomic/fragment state that reflec ts the actual electronic state of each fragment in-the-molecule\, which ca n then be used to properly define IBEs.

Since their discover in year 1989\, terrestrial TLEs ha ve been investigated in an effort to determine their chemical impact in th e upper mesosphere. In addition\, the detection of possible extraterrestri al TLEs have been proposed as a tool to study lightning beyond our planet. \nDifficulties inherent in the study and observation of the natural plasma located in the lower ionosphere give value to the development of models. We extend previous models of the impact of quasi-electrostatic field (QE) in the terrestrial mesosphere produced by cloud-to-ground (CG) lightning d ischarges\, providing the community with new tools to interpret observatio ns from spacecraft. In addition\, we use a Finite Difference Time-Domain ( FDTD) model to investigate possible TLEs existence in the atmosphere of gi ant planets caused by lightning-emitted electromagnetic pulses (EMP). Fina lly\, we apply these models to the case of Venus to investigate the mesosp heric optical signature produced by hypothetical Venusian intra-cloud (IC) lightning\, proposing an indirect method to determine the existence of li ghtning discharges in Venus from the Japanese spacecraft Akatsuki\, orbiti ng Venus since December 2015.\n\nhttps://indico.ific.uv.es/event/2851/cont ributions/4292/ LOCATION:Facultad de Química (USC) Aula Química Analítica URL:https://indico.ific.uv.es/event/2851/contributions/4292/ END:VEVENT BEGIN:VEVENT SUMMARY:Mejora de la conductividad térmica de líquidos y de sólidos por adición de nanopartículas.

Understanding their adsorption behaviour is therefore an issue of major relevance from a practical point of view\, but also from a fundament al one\, as it is common that the properties of the adsorbed fluid are dif ferent from those in the bulk. One intriguing finding in this context is t he observation that the adsorption isotherm of some simple gases (such as argon) on silicalite-1 exhibits a sub-step at intermediate loadings wherea s others (such as methane) do not. Even though considerable experimental a nd theoretical efforts have been made\, the origin of this sub-step is not clear. Some authors claim that this behaviour is a result of a fluid-like to solid-like transition of the adsorbed fluid\, whereas others attribute it to a zeolite structural change. \n\nWith the aim of providing more inf ormation that may aid to understand the appearance of sub-steps in the ad sorption of some gases in silicalite-1\, we have carried out a comprehensi ve experimental and simulation study of the adsorption of argon and toluen e on the structurally similar zeolite silicalite-2. Both zeolites exhibit a similar structure consisting on a three-dimensional network of fairly na rrow cylindrical channels with diameters in the range of 5.0 to 5.6 Å. Th e essential difference lies in the fact that silicalite-1 consists of an a rray of parallel cylindrical pores intersected by sinusoidal channels\, wh ereas in silicalite-2 all the pores are linear (see Figure 1). \n\nFirst we performed volumetric experiments that confirm that the adsorption of ar gon and toluene on silicalite-2 also exhibits a sub-step at half loading ( see Figure 2)\, suggesting that this behaviour does not depend on the spec ific structural details of the pores. Subsequently\, the microscopic orig in of this sub-step was investigated by means of molecular simulations. Ho wever\, the agreement between the experimental and simulated adsorption is otherm was only qualitative\, evidencing deficiencies of the models used t o describe the interactions between the different components in the system .\n\nThus the structure of the adsorbate/adsorbent system was further inve stigated by performing powder diffraction experiments at three different l oads: empty\, at half-load (before the sub-step) and at high load (after t he sub-step). These data were used as input of N-Reverse Monte Carlo simu lations to obtain atomic structural models compatible with the experimenta l diffractograms. In both instances\, namely adsorption of argon and tolu ene\, a good fit of the experimental data was only obtained when incorpora ting the zeolite flexibility\, which shows that the structure of the zeoli te can change at high loads or when the size of the adsorbed molecules is comparable to that of the pores. In the case of argon\, after the sub-step \, a considerable order of the fluid also builds up\, suggesting that the sub-step might be attributed to a fluid structural change facilitated by a slight deformation of the zeolite.\nInterestingly\, the structural models obtained from Monte Carlo and N-Reverse Monte Carlo simulations are signi ficantly different\, even at half loading. We ascribe these discrepancies to deficiencies in the adsorbent-adsorbate interatomic potential.\n\nhttps ://indico.ific.uv.es/event/2851/contributions/4290/ LOCATION:Facultad de Química (USC) Aula Matemáticas URL:https://indico.ific.uv.es/event/2851/contributions/4290/ END:VEVENT BEGIN:VEVENT SUMMARY:Generando hidrógeno con agua y luz: Trisulfuros ternarios bidimen sionales en celdas fotoelectroquímicas DTSTART;VALUE=DATE-TIME:20170717T164500Z DTEND;VALUE=DATE-TIME:20170717T171500Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4289@indico.ific.uv.es DESCRIPTION:Speakers: Eduardo Flores (Dpto. de Física de Materiales M-04\ , Facultad de Ciencias\, Universidad Autónoma de Madrid)\nDesde 1972 cuan do Fujishima y Honda[1] demostraron que la ruptura de la molécula de agua con luz y TiO2 como fotoánodo era posible\, el interés por investigar c ompuestos capaces de generar de hidrógeno mediante la disociación de H2O en celdas fotoelectroquímicas (PECs) ha ido aumentando notablemente y co n una mayor intensidad en los últimos años[2\,3].

New optical long-slit spectroscopic observations clearly show the existence of three spatially separated narrow components in their emission lines\, two of them blue and red-shifted respectively wi th respect to a third one that is found to be at the systemic velocity. Th e velocity offset between the blue-shifted and the red-shifted components is ∼500 kms−1\, and is responsible of the double-peak emission lines. We show that the blue and red-shifted components are produced by two indiv idual AGN. The third systemic component is however a star-bursting galaxy located in the inter AGN region. We thus claim that Mrk 622 is an unresolv ed\, spectroscopically confirmed binary AGN\, that harbour a dwarf galaxy in between the pair of AGN.\n\nhttps://indico.ific.uv.es/event/2851/contri butions/4287/ LOCATION:Facultad Química (USC) Aula 2.12 URL:https://indico.ific.uv.es/event/2851/contributions/4287/ END:VEVENT BEGIN:VEVENT SUMMARY:Medida de producción de isótopos b+ para verificación de rango en protonterapia DTSTART;VALUE=DATE-TIME:20170718T134000Z DTEND;VALUE=DATE-TIME:20170718T135500Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4286@indico.ific.uv.es DESCRIPTION:Speakers: Carlos Guerrero (Universidad de Sevilla)\nLa verific ación de la posición del pico de Bragg durante el tratamiento de tumores con haces de protones es uno de los aspectos clave para una mayor eficaci a de la protonterapia.

Una parte importante de la mejora de la eficien cia energética se centra en la reducción del consumo energético de los edificios\, lo cual hace necesario desarrollar métodos de caracterizació n térmica de sus componentes\, tales como los muros. Con este objetivo\, se ha desarrollado un experimento en condiciones dinámicas que permita es timar la resistencia y la capacidad térmica de diferentes muros\, ya sean homogéneos o heterogéneos. \nEn este experimento se ha construido una c aja cuasi-adiabática en la que el muro a analizar se ubica en una de sus caras. En esta caja se procede a generar una excitación térmica de dicho muro mediante una exposición controlada a radiación generada por lámpa ras incandescentes. Esta radiación incide sobre sus superficies interior y exterior\, y provoca variaciones temporales de las temperaturas en el in terior y el exterior de la caja. Esta variación temporal en las temperatu ras de las superficies del muro a analizar va a ser medidas en diferentes instantes de tiempo mediante la obtención de termografías. La utilizaci ón de temperaturas de superficie medidas utilizando termografías supone una innovación respecto al tradicional uso de medidas de flujo de calor r ealizadas con fluxómetros. Al tratarse de un experimento en condiciones d inámicas donde la utilización de fluxómetros está limitada teóricamen te resulta útil estudiar el uso de termografías. La limitación del uso de fluxómetros se debe a que sus medidas producen una amplificación de l as altas frecuencias que pueden estar presentes en las señales de excitac ión del muro\, siendo dicha amplificación contradictoria con las observa ciones físicas.\nEn el presente trabajo se ha utilizado un modelo físico en forma de circuito térmico para representar el balance de energía que atraviesa el muro para determinar su resistencia y su capacidad térmicas . El modelo utiliza como variables independientes las temperaturas ambient e y la irradiancia\, y como variables independientes las temperaturas de s uperficie. El procedimiento puede ser validado registrando un número sign ificativo de series temporales que permita obtener los valores de la resis tencia y capacidad térmicas junto a una medida de su incertidumbre. Y una vez obtenidos estos valores de forma experimental\, se puede proceder a s u comparación con los valores nominales especificados por el fabricante p ara la resistencia y capacidad térmica del muro analizado.\n\nhttps://ind ico.ific.uv.es/event/2851/contributions/4285/ LOCATION:Facultad Química (USC) Aula de Física URL:https://indico.ific.uv.es/event/2851/contributions/4285/ END:VEVENT BEGIN:VEVENT SUMMARY:Diseño de una practica de la laboratorio de medición de ozono se gún el método de Schönbein DTSTART;VALUE=DATE-TIME:20170718T164500Z DTEND;VALUE=DATE-TIME:20170718T170000Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4284@indico.ific.uv.es DESCRIPTION:Speakers: Añel Juan Antonio (EPhysLab\, Universidade de Vigo) \nEl ozono tropósferico se conoce desde la década de 1830 y nada más de scubrir su existencia se inventaron métodos de medida para él por la cre encia de que podía poseer cualidades de curación de enfermedades respira torias.

The High-Gradient (HG) know- how and technology for normal-conducting accelerating RF (Radio-Frequency) electron linac (linear accelerator) structures recently developed for pro jects such as CLIC (CERN)\, has raised the achievable accelerating gradien t from 20-30 MV/m up to 100-120 MV/m. This gain has come through a better understanding of the high-power RF vacuum arcs or breakdowns (BD) phenomen a\, the development of quantitative HG RF design methods and refinements i n fabrication techniques. This can allow for more compact linacs also for protons\, which is potentially important in the new trend in hadron-therap y of using linacs able to provide protons of 70-230 MeV or light ions of 1 00-400 MeV/u. Linacs are of particular interest for medical applications b ecause they can provide a high degree of flexibility for treatment\, such as running at 100-400 Hz pulse rate and pulse-to-pulse beam energy (and in tensity) variations. This kind of accelerator is very well suited to treat moving organs with 4D multi-painting spot scanning technique. Project stu dies like TULIP are taking advantage of these developments and pursuing me dical linacs of reduced size.\n\nHG operation\, which is carried out under ultra-high vacuum conditions (~10-9 mbar)\, is limited by the BD phenomen a and is characterized by the BD-Rate (BDR) or number of BD per pulse and meter. New fresh structures initially operate at a reduced performance and must be conditioned through extended high-power rf operation until the ma ximum operational gradient is reached. This process is a time consuming\, and consequently costly task (> 350 million pulses) which is important to understand and reduce. The IFIC HG-RF laboratory is designed to host a hig h-power and high-repetition rate facility for testing S-Band (2.9985 GHz) normal-conducting RF structures. This facility will allow the development\ , RF conditioning and studies of the BD phenomena in HG structures.\n\nhtt ps://indico.ific.uv.es/event/2851/contributions/4281/ LOCATION:Facultad Química (USC) Aula Química Física URL:https://indico.ific.uv.es/event/2851/contributions/4281/ END:VEVENT BEGIN:VEVENT SUMMARY:Classical physics and the bounds of quantum correlations DTSTART;VALUE=DATE-TIME:20170717T161500Z DTEND;VALUE=DATE-TIME:20170717T164000Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4280@indico.ific.uv.es DESCRIPTION:Speakers: Diego Frustaglia (Universidad de Sevilla)\nThe parti cular set of numerical bounds satisfied by quantum correlations has been i ntensively studied as a plausible gateway to the first principles of quant um theory\, which up to date remain elusive.

We demonstrate this finding by implementing classical microwaves that propagate along met er-size transmission-line circuits and reproduce the probabilities of thre e emblematic quantum experiments [1].

This dust is injected into the interstellar medium and plays a key role in the evolution of astronomical objects from galaxie s to the embryos of planets. However\, the processes involved in dust form ation and evolution are still a mystery. The increased angular resolution of the new generation of large telescopes\, is providing for the first tim e a detailed view of the conditions in the dust formation zone of evolved stars\, as shown by our first observations with ALMA (Cernicharo et al. 20 13\, Agúndez et al. 2017).\nThe aim of the NANOCOSMOS project is to take advantage of these new observational capabilities to change our view on th e origin and evolution of dust grains. We are combining\nastronomical obse rvations\, modelling\, and top-level experiments to produce star dust anal ogues in the laboratory and identify the key species and steps that govern their formation. We have built two innovative setups: the Stardust chambe r to simulate the physical conditions of the atmosphere of evolved stars\, and the gas evolution chamber to identify novel molecules in the dust for mation zone.\nWe are also improving existing laboratory setups and combine different techniques to achieve original studies on individual dust grain s\, their processing to produce complex polycyclic aromatic hydrocarbons\, the chemical evolution of grain precursors and how dust grains interact w ith abundant astronomical molecules. Our simulation chambers have been equ ipped with state-of-theart in situ and ex situ diagnostics.\nOur astrophys ical models\, improved by the interplay between observations and laborator y studies\, provide powerful tools for the analysis of the wealth of data provided by the new generation of telescopes. The synergy between astronom ers\, vacuum and microwave engineers\, molecular and plasma physicists\, s urface scientists\, and theoreticians in NANOCOSMOS is the key to provide a cutting-edge view of cosmic dust.\n\nhttps://indico.ific.uv.es/event/285 1/contributions/4270/ LOCATION:Santiago de Compostela\, Facultade de Química Aula Magna URL:https://indico.ific.uv.es/event/2851/contributions/4270/ END:VEVENT BEGIN:VEVENT SUMMARY:The RSEF Exterior Section DTSTART;VALUE=DATE-TIME:20170717T110000Z DTEND;VALUE=DATE-TIME:20170717T112000Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4269@indico.ific.uv.es DESCRIPTION:Speakers: Antonio Picón ()\n"Recently the RSEF has created an Exterior Section\, aiming at representing the members that are\nstaying a broad.

As a first example\, we show how t he dynamical modulation of the qubit-field coupling strength in a circuit quantum electrodynamics architecture mimics the motion of the qubit at rel ativistic speeds. This allows us to propose a realistic experiment to dete ct microwave photons coming from simulated acceleration radiation [1]. We show that this accelerated radiation can be used to generate entanglement between a pair of qubits [2]. Moreover\, we discuss the effects of relativ istic motion on single-atom and two-atom Dicke superradiance [2]. Finally\ , we show that it is possible to simulate effective velocities which even exceed the speed of light in the medium\, giving rise to the quantum count erpart of Cerenkov radiation\, namely Ginzburg radiation [3].\nWe propose as well an implementation of a twin-paradox scenario in superconducting ci rcuits\, with velocities as large as a few percent of the speed of light [ 4]. Ultrafast modulation of the boundary conditions for the electromagneti c field in a microwave cavity simulates a clock moving at relativistic spe eds. Since our cavity has a finite length\, the setup allows us to investi gate the role of clock size as well as interesting quantum effects on time dilation. In particular\, our theoretical results show that the time dila tion increases for larger cavity lengths and is shifted due to quantum par ticle creation. \nThe combination of both techniques generates a toolbox f or studying relativistic phenomena in quantum field theory with supercondu cting circuits. We will discuss some possible future applications.\n\nhttp s://indico.ific.uv.es/event/2851/contributions/4253/ LOCATION:Facultad Química (USC) Aula Química General URL:https://indico.ific.uv.es/event/2851/contributions/4253/ END:VEVENT BEGIN:VEVENT SUMMARY:Graphene based nuclear spin quantum bits DTSTART;VALUE=DATE-TIME:20170719T154500Z DTEND;VALUE=DATE-TIME:20170719T160500Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4247@indico.ific.uv.es DESCRIPTION:Speakers: Noel Garcia (International Iberian Nanotechnology La boratory)\nIn this work\, we study the possibility of hydrogenated graphen e based Qubits.

The strong point of this approach is the ability to simultaneously prov ide a good description of bulk properties\, like binding energies and mult ipole moments\, as well as an accurate and detailed account of excitatio n energies and transition probabilities.\n\n As a validation of the theor y in this talk we present a study of the Magnesium isotopic chain.

The advantages of the present approach as compared to the she ll-model one are the added value of the intrinsic system interpretation an d that the interaction\, the Gogny force\, is well known for its predictiv e power and good performance for bulk properties all over the chart of nuc lides. \n\n\\vspace{1cm}\n\n1.- M.

Particularmente\, en las células solares de calcopirita la unión entre el CuGaS2 y la capa “buffer” (CdS o ZnSe) está formada p or materiales con diferentes anchuras de banda prohibidas\, diferentes afi nidades electrónicas y diferentes posiciones energéticas del nivel de Fe rmi. La consecuencia de estas diferencias se refleja en la discontinuidad de la banda de valencia y conducción\, además de la formación de un mom ento dipolar en la interfase que genera un escalón en el potencial electr ostático. \nDe acuerdo a un resultado previo [3]\, el alineamiento de ban das de las interfases entre el CuGaS2/CuAlSe2 y CuGaS2/ZnSe muestran las c aracterísticas adecuadas para el diseño y desarrollo de células solares de película delgada. Los resultados sugieren que las interfases entre el los afectan a la eficiencia de conversión en células solares [4].\nSin e mbargo\, las complicaciones teóricas que se derivan de las complejas inte racciones entre los enlaces de las interfases y el desajuste de la red ent re los compuestos han impedido el desarrollo de modelos analíticos genera les capaces de predecir con precisión las magnitudes en la discontinuidad de las bandas [5]. El gran desajuste de la red entre el CuGaS2 y el mater ial de contacto (CuAlSe2 ~ 6% y ZnSe ~ 5%) y el alineamiento de bandas del tipo II entre las dos interfases\, han motivado este estudio de las heter oestructuras con CuGaS2\, debido a que el tipo de alineamiento va acompañ ado de una separación de las carga\, lo cual es ventajoso para este tipo de células solares.\nHaciendo uso de la metodología de primeros principi os\, combinando la teoría del funcional de la densidad (DFT) y cálculos cuánticos (funcionales híbridos)\, obtuvimos los alineamientos de bandas de las heterouniones entre el CuGaS2 y el CuAlSe2 y ZnSe.

N evertheless\, the nature of dark energy constitutes one of the biggest puz zles in Physics. Shedding light on dark energy requires the construction o f big experiments that survey large volumes of the Universe. One of those experiments is The Dark Energy Survey (DES) [2].\nOne of the observational probes that may unravel the nature of dark energy is the weak gravitation al lensing [3]. Weak-lensing is produced by the gravitational bending of t he trajectory of photons by gravitational fields leading to the deflection of the light rays. Thus\, the light emitted by foreground distant galaxie s is deflected by the matter located between them and the observer. For ex tended sources\, in addition to the change in position\, this leads to two observational effects: an isotropic size enlargement (magnification) and an elongation/shrink along one axis (shear). Since the surface brightness is preserved\, the isotropic size enlargement due to magnification produce s an increase on the observed flux of the background galaxies. This allows to see galaxies that would be beyond the detection threshold if gravitati onal lensing was not present. Thus\, nearby the lenses the\nobserved densi ty of sources is increased. This effect is known as number-count magnifica tion and allows to probe the convergence profile of the lens sample select ed\, that is a proxy for the matter profile [4].\n\nWeak-lensing magnifica tion by voids\n\nExtensive wide-field programs have allowed accurate measu rement of weak lensing effects. Previous magnification measurements involv e the use of very massive objects as lenses\, such as luminous red galaxie s (LRGs) and clusters [5]\, or high redshift objects as sources\, such as Lymanbreak galaxies (LBGs) or quasars (QSOs) [6\,7].\nLyman break galaxies and quasars have demonstrated to be a very effective population of backgr ound samples to do magnification studies due to its high lensing efficienc y. However\, deep surveys or large areas are needed to reach a significant amount of these objects. Thus\, shallow or small area surveys require the selection of a more numerous population of source galaxies to allow the m easurement of the magnification signal.\nA new technique has been develope d at the Dark Energy Survey [8]\, where galaxies selected only by its phot o-z\, are used both as lenses and sources. This procedure simplifies the a nalysis as no additional processing is needed to construct the sample (con trary to the methodology present on the literature). This new methodology allows the detection of the magnification signal on small area surveys\, s uch as the DES Science Verification data-set\, but the power of this metho dology also applies to large area surveys such as LSST or the final footpr int of DES\, with 5000 deg^2 . The huge decrease on the shot-noise due to the increase on the surface density of sources\, allows the selection of m ore exotic lenses\, such as voids.\nVoids are the emptiest regions of the cosmic web that conform the large-scale-structure of the Universe (LSS) [9 ]. Thus\, their structure and evolution is dominated by dark energy. Previ ous works on simulations show that different void properties such as their ellipticity or its total matter radial distribution (void-profile) is str ongly dependent on the modified gravity model used [10-17].\nDue to the pr esence of dark matter\, the total matter distribution is only accessible t hrough gravitational lensing. Thus\, the determination of the void-profile with weak-lensing magnification constitutes a new and independent probe f or dark energy.\n\nReferences\n\n[1] S.

Recently\, there has been a gr owing interest in this type of system\, in a large part\, due to theoretic al work that suggests that Andreev levels are precursors of Majorana zero modes. Accordingly\, it has been proposed that chains of such impurities c ould be engineered\, under appropriate conditions\, into a topological sup erconductor [1-9]. A semiconductor quantum dot coupled to a superconductor constitutes a versatile platform to investigate\, in a controllable and q uantitative manner\, the physics of the corresponding single-impurity limi t. Here\, we have employed single quantum dots defined in an InAs nanowire \, coupled strongly to a superconductor and weakly to a normal metal probe \, to study the Andreev levels by tunneling spectroscopy. First\, we explo it the ability to tune the hybridization of the quantum dot and the superc onductor to quantitatively investigate the energy scaling of Andreev level s. We demonstrate that the energy of such sub-gap excitations scales with the ratio of the Kondo temperature and the superconducting gap. We further leverage the electrical control over device parameters to obtain an exper imental phase diagram of the possible ground states: a spin singlet or a m agnetic doublet. Our experimental results show remarkable quantitative agr eement with numerical renormalization group calculations [10]. In parallel \, we have studied the spin texture of the Andreev levels in the presence of an external magnetic field. We demonstrate that the Zeeman effect resul ts in a splitting of the sub-gap states only when the ground state is a sp in singlet. In this case\, the applied magnetic field can also lead to a q uantum phase transition to a spin-polarized ground state [11]. The herein demonstrated electrical tuning of Andreev levels as well as their spin-pol arization could be harnessed to pursue proposals of realizing a topologica l superconductor using quantum dot arrays [7-9]. \n\n[1] S.

These systems mix the spin with orbital degrees of freedom. As the orbital wavefunction is sensitive to electric fields\, this mixing all ows the possibility of manipulating spins entirely by electric means. \n\n The large spin-orbit coupling in the valence band of group IV semiconducto rs provides then with an electric field knob for hole based spin-qubit man ipulation. Si and Ge are also known for their extraordinary coherence prop erties\, making them two of the most promising candidates to host spin-qub its.\n\nIn this work we consider acceptor impurities placed in these hosts . These acceptors behave as spin-3/2 particles with remarkable properties that can be tuned through both electric and magnetic fields. We find that the spin manipulation of holes bound to acceptors in engineered SiGe quant um wells depends very strongly on the electric field applied and on the he terostructure parameters. The g-factor is enhanced by the Ge content and c an be tuned by shifting the hole wave-function between the heterostructure constituent layers. \nThe lack of inversion symmetry induced both by the quantum well and the electric fields together with the g-factor tunability allows the possibility of different qubit manipulation methods such as el ectron spin resonance\, electric dipole spin resonance and g-tensor modula tion resonance. Rabi frequencies up to hundreds of MHz can be achieved wit h heavy-hole qubits\, and of the order of GHz with light-hole qubits. \nWe also find that by carefully choosing the parameters of the system such as the in-plane magnetic field and the applied vertical electric field it is possible to tune the entanglement and coherence properties of the system. \n\nhttps://indico.ific.uv.es/event/2851/contributions/4228/ LOCATION:Facultad de Química (USC) Aula Química Inorgánica URL:https://indico.ific.uv.es/event/2851/contributions/4228/ END:VEVENT BEGIN:VEVENT SUMMARY:Electrical discharges in the upper atmosphere of the Earth and ot her planets of the Solar System DTSTART;VALUE=DATE-TIME:20170719T130500Z DTEND;VALUE=DATE-TIME:20170719T135500Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4227@indico.ific.uv.es DESCRIPTION:Speakers: Francisco J.

Accurate measurements of the parity-violating asymmetry in elastic elect ron scattering from nuclei can be used to determine Standard Model couplin gs\, such as the weak-mixing angle\, or higher-order radiative corrections \, as well as to extract specific information on the nuclear and nucleon s tructure. To this end\, low uncertainties are required from modeling some confounding nucleon and nuclear structure effects\, including isospin mixi ng\, nucleon strangeness content or Coulomb distortion. We estimate the si zes and theoretical uncertainties of such effects for a proton and a carbo n 12 targets. An experimental precision in the asymmetry of a few tenths o f a percent may be reachable under certain kinematic conditions\, that are also discussed here for the same nuclear target.\nThis high precision par ity-violating asymmetry in elastic electron scattering can also be used to relate in a very simple manner the elastic electron-nucleus scattering cr oss section with the elastic weak-neutral neutrino-nucleus cross section f or even-even targets or\, more generally\, for any target in coherent scat tering. This novel relationship allows us to exploit experimentally well-d etermined quantities (related to electron-nucleus scattering) to predict a s-yet unknown observables (weak neutral neutrino-nucleus cross sections). This idea is simply extended to link electron scattering to an even more u ncertain magnitude: the detection rate of weak-interacting massive particl es\, that are dark matter candidates.\n\nhttps://indico.ific.uv.es/event/2 851/contributions/4224/ LOCATION:Facultade de Química (USC) Aula Química Física URL:https://indico.ific.uv.es/event/2851/contributions/4224/ END:VEVENT BEGIN:VEVENT SUMMARY:Light-matter interfacing with quantum dots: a polarization tomogra phy approach DTSTART;VALUE=DATE-TIME:20170718T165000Z DTEND;VALUE=DATE-TIME:20170718T171000Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4223@indico.ific.uv.es DESCRIPTION:Speakers: Carlos ANTON SOLANAS (Center of Nanosciences and Nan otechnology (C2N)\, CNRS\, University Paris-Sud\, University Paris-Saclay\ , C2N Marcoussis\, Marcoussis\, France)\nWe report on the polarization tom ography of a resonantly-driven quantum-dot cavity-QED device.

Understanding the role of quantum nuclear effects and intramolecular interactions in the mot ion of molecules in carbon nanotubes is deeply fundamental. Very recent ex perimental measurements at low temperatures (2-5 K) of Ohba [1] revealed t hat much more molecules of nitrogen than helium atoms absorb in small diam eter (below 0.7 nm) carbon nanopores\, despite of the larger kinetic diame ter of the former. Using the helium density functional formulation for a l arge 4He droplet containing a carbon nanotubes inside\, we first show that the experiment can be understood by considering very large zero-point eff ects in the helium motion\, which includes the formation of cavities with zero helium densities [2]. Second\, we present an ad-hoc developed nuclear wave-function treatment to provide a detailed insight into the effects of quantum confinement for both N2 and 4He clusters in carbon nanotubes as a function of the tube diameter [3]. Third\, we describe our novel pairwise potential model [3] describing the gas adsorption to carbon materials whi ch relies on DFT-based symmetry-adapted perturbation theory.

The LMM is a period of great interest sinc e it was one of the few cold periods in recent centuries that persisted fo r several decades. \nHere\, we present the first direct instrumental evide nce of the daily atmospheric circulation over the eastern Atlantic during the LMM based on wind direction observations taken aboard ships over the E nglish Channel. To do so\, we derived two sets of monthly atmospheric circ ulation indices based on the persistence of the wind direction in the four cardinal directions and in 8-point wind roses for the 1685-2014 period. T hey provide the longest observational records of the atmospheric circulati on to date\, allowing us to explore the variability of the atmospheric cir culation in a wide range of time-scales. \nThe analysis of these indices i ndicate that the LMM was characterized by a pronounced meridional circulat ion and a marked reduction in the frequency of westerlies all year round\, as compared to the present (1981-2010). The winter circulation contribute d the most to enhance the cold conditions through an overall increase of n ortherly winds. Nevertheless\, our findings also show a LMM more heterogen eous than previously thought\, displaying contrasting spatial patterns in circulation and temperature\, as well as large decadal variability.\nBased on the circulation characteristic of each winter\, we provide a new obser vational-based catalogue of winters for the LMM\, reassessing the indirect evidences available in the literature about the temperature conditions of the LMM. Our assessment confirms the majority of extremely cold winters d ocumented in the literature\, but also uncovers the existence of additiona l undocumented cold winters and a substantial number of mild winters that had been unnoticed so far. The outcomes also suggest a non-stationarity of the North Atlantic Oscillation (NAO) pattern within the LMM\, which has n ot been reported before\, with extremely cold (moderate) winters being ass ociated to negative phases of a “high-zonal” (“low-zonal”) NAO pat tern.\n\nhttps://indico.ific.uv.es/event/2851/contributions/4221/ LOCATION:Facultad Química (USC) Química Inorgánica URL:https://indico.ific.uv.es/event/2851/contributions/4221/ END:VEVENT BEGIN:VEVENT SUMMARY:Divulgación de la Física de Materiales en Asturias: Nuestras exp eriencias ante diferentes audiencias DTSTART;VALUE=DATE-TIME:20170718T140000Z DTEND;VALUE=DATE-TIME:20170718T143000Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4220@indico.ific.uv.es DESCRIPTION:Speakers: Pedro Gorria (Universidad de Oviedo)\nEn esta comuni cación presentamos nuestra trayectoria de divulgación de la Física a lo largo de los últimos años en Asturias ante audiencias muy diversas\, de sde colegios de educación primaria y secundaria hasta centros culturales en pequeñas localidades rurales.

Synthesis and physical characterization DTSTART;VALUE=DATE-TIME:20170717T161500Z DTEND;VALUE=DATE-TIME:20170717T163000Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4214@indico.ific.uv.es DESCRIPTION:Speakers: Marco Antonio Mascos Millán (Departamento de Físic a Aplicada\, Universidade de Vigo\, E-36310\, Vigo\, Spain)\nIntroduction\ n\nIt is undeniable that the energy and the services that provides are a k ey issue in the development of the humanity and contribute directly to the well-being of people\, among other things. Thus\, more specifically\, it is crucial to improve the thermal capacities of fluids\, since there is a direct relationship between the heat transfer and storage abilities of wor king fluids and the thermal performance of most installations [1]. Additio nally\, the flexibility of thermal facilities or the correction of possibl e unforeseen mismatches between offer and demand can be improved by means of energy storage. A possibility to enhance the efficiency and optimize op erating time of those thermal processes is the utilization of functional m aterials named Phase Change Materials\, PCMs\, which can storage and relea se large amounts of latent heat with a slight temperature change [1\, 2]. In the last years\, new materials with enhanced properties were developed by dispersing particles with high thermal conductivities and nanometric si ze into these PCMs [3]. Thermal conductivity is the key property in order to improve the charging and discharging mechanisms whereas heat capacity a nd melting enthalpy allow quantifying both sensible and latent heat storag e capabilities. \nIn this work\, oleylamine-coated gold nanoparticles were synthesized and dispersed in a polietilenglicol with a low molecular weig ht to formulate new nano-enhanced phase change materials\, NePCMs. The the rmal conductivity\, heat capacity and enthalpy of these new NePCMs were ex perimentally determined and the temperature and nanoadditive concentration influences on these physical properties were analysed.\n\n\nMethods\n\n~1 2nm oleylamine-coated gold nanoparticles were synthesized following a slig htly modified procedure already present in the literature [4]. Namely\, a solution of 3mL (6.4mmol) of oleylamine and 49mL of toluene was heated to reflux in a 100mL three-neck round-bottom flask and\, subsequently\, a sol ution containing 50mg (0.13mmol) of HAuCl4\, 1.74mL (3.7mmol) of oleylamin e and 1mL of toluene was quickly injected. The reaction mixture was magnet ically stirred and refluxed for two hours. The as-synthesized gold nanopar ticles were precipitated by adding 50mL of ethanol to the previous mixture and separated via centrifugation (5000rpm\, 20min.). In order to remove a ny undispersed residue\, the precipitate was washed three times with ethan ol (40mL). Eventually\, the black product was dried at 40ºC overnight. Al l reagents\, HAuCl4 (trace metals basis\, ≥99.9%)\, oleylamine (technica l grade\, 70%) and toluene (ACS reagent\, ≥99.5%) were purchased from Si gma-Aldrich and used without further preparation or purification. Absolute ethanol was also used as received.\nAs base material it was used a pharma ceutical-grade polyethylene glycol with an average molecular weight of 400 g/mol\, PEG400\, supplied by Panreac AppliChem. Purity and molecular weig ht of PEG were determined through electrospray ionisation mass spectrometr y. Thermal stabilities of both gold nanoparticles and PEG400 were studied through thermogravimetric analysis\, TGA\, with a Setsys 16 TG-DTA (Setara m Instrumentation). NePCMs were prepared following a two-step method by di spersing the dry nanoparticles in the PEG400 with an ultrasonic bath (Ultr asounds\, JP Selecta S.A.) working at a frequency of 20 kHz and with a pow er of 200 W. Temporary stability of dispersions was evaluated by dynamic l ight scattering technique using a Zetasizer Nano ZS (Malvern Instruments). Thermal conductivity at temperatures from (283 to 323) K was measured usi ng a KD2-Pro (Decagon) device which is based on the well-known transient h ot wire technique [5]. Heat capacity was measured in the range between (19 3 and 313) K with a differential scanning calorimetry\, DSC\, Q2000 (TA In struments) equipped with a RSC90 system of cooling and functioning in the quasi-isothermal method (TMDSC) [6]. This last device was also used to ana lyse the characteristics of (solid - liquid) phase transitions in the temp erature range between (193 and 313) K.\n\n\nResults and conclusions \n\nTh ermal conductivities for both PEG400 and NePCMs decrease smoothly with tem perature over the analysed temperature range. A perceptible increase in th e thermal conductivity of gold nanoparticle dispersions is already appreci ated in relation to base material even for low concentrations. In terms of heat capacity\, we have found characteristic behavior in NePCMs in relati on to the influence of nanoparticle loading. Figure 1 shows the thermogram s obtained for PEG 400 and for the dispersion at 0.1 wt.%\, using cooling rates between (1 and 10) K•min-1 and a heating rate of 2 K/min. In this regard\, we can underline that the addition of gold nanoparticles may play a role in an easier nucleation during solidification\, reducing the tempe rature range in which fusion happens. \n\n \n\nReferences\n\n[1] B.

The properties of the transition are intimately related to the isospin dependence of the nu clear forces at low baryon densities. \nFinite-range Gogny nuclear interac tions are widely used in nuclear structure calculations but there are fewe r studies of neutron stars with these interactions. \nIn this work\, we in vestigate the core-crust transition in neutron stars using several Gogny f orces and analyse the deduced crustal thickness and crustal moment of iner tia of the star. \nIn a first stage\, we calculate the second-\, fourth- a nd sixth-order coefficients of the Taylor expansion of the energy per part icle of asymmetric nuclear matter in powers of the isospín asymmetry for Gogny forces. \nThese coefficients provide information about the departure of the symmetry energy from the widely used parabolic law and can influen ce significantly the results for the location of the inner Edge of neutron star crusts. Next\, we evaluate the neutron star core-crust transition de nsity by looking at the onset of thermodynamical instability of the liquid core. The analysed Gogny forces predict the ranges 0.094 fm-3 ≤ ρt ≤ 0.118 fm-3 for the transition density and 0.339 MeV fm-3 ≤ Pt ≤ 0.665 MeV fm-3 for the transition pressure. The transition densities of the Gog ny forces show an anticorrelation with the slope parameter L of the symmet ry energy\, whereas the transition pressures are not found to correlate wi th L. Finally\, the fraction of the mass and moment of inertia of the neut ron star that reside in the crust are evaluated using the forces that prov ide stable solutions of the Tolman-Oppenheimer-Volkov equations.\n\nhttps: //indico.ific.uv.es/event/2851/contributions/4206/ LOCATION:Facultade de Química (USC) Aula Química Física URL:https://indico.ific.uv.es/event/2851/contributions/4206/ END:VEVENT BEGIN:VEVENT SUMMARY:High throughput production of solid targets for laser-driven parti cles acceleration through MEMS based processing.

[1]. Laser-driven ion acceleration has been observed since earl y experiments of solid target irradiation with lasers\, and it has been ex plained in the framework of Target Normal Sheath Acceleration (TNSA) model . Particle acceleration originates from the rear surface of a solid target \, typically a thin metallic foil\, and is caused by the charge separation field generated by laser-plasma interaction on the front target surface a t laser intensities of 1018÷1020 W/cm2 (Fig.1 (a)). Until now\, targets s upply strategies have been principally based on fabrication and assembly o n an individual basis. However\, this approach is not suitable to exploit the full potential of high repetition rate HPLs. Therefore\, the developme nt of high throughput target fabrication processing for ultra-intense lase r-plasma experiments is receiving many efforts. In this regard\, the appro ach based on micro-/nano-electromechanical systems (N/MEMS) technology\, w hich evolved from semiconductor device manufacturing\, is a very attractiv e solution [2]. It provides\, in fact\, parallel processing and the possib ility to achieve complex target design with micro-nano sized features on a variety of materials.\nHere\, we present the fabrication of thin layer me mbranes made by aluminum\, both free-standing and supported by a nanometri c thickness of SiO2\, embedded in a silicon frame. Membranes were fabricat ed with variable SiO2 and aluminum thicknesses according the route schemat ized in Fig. 1(b)\, which combines photolithography\, thin layer depositio n techniques\, wet and dry etching. Both wafer sides were processed in suc h a way to obtain\, on front side\, the openings for the aluminum membrane s which are then deposited by sputtering on the back side\, with thickness es equal to 0.25\, 0.5 and 1 micron\, respectively. Some of the obtained t argets are shown in Fig.1(c) characterized by optical\, electron\, and con focal microscopy. Individual targets contain up to 16\, 1 mm2 membranes av ailable for experiments\, and were used for laser-plasma experiments at th e laser installation of Proton Laser Applications\, S.L.\, which has devel oped a table-top laser system running at 3 TW with an intrinsic repetition rate up to 100 Hz [3]. The experimental setup is schematized in Fig. 1(d) showing in detail the interaction chamber where targets are easily locate d thanks to a purpose made holder which carries up to 16 individual target s\, resulting in 256 membranes available for consecutive shots. Results of preliminary experiments\, represented in Fig.1 (e) for 0.5 μm aluminum m embranes\, show the achievement of successful proton acceleration up to 2 MeV almost constant within the spanned focal plane (distances from focus p osition are listed in the legend\, in microns)\, and having the peak value in the focus\, as expected. This maximum energy is slightly higher than p revious results from plain foils\, and corresponds to the expectations wit h respect to the laser energy on target. We expect to improve this perform ance by further developments of our system directed from one side to incre ase the laser pulse energy\, and from the other\, to involve more sophisti cated target designs with micro-nano texturized surfaces which\, according to particle-in-cell simulations [4]\, should improve the coupling\, and t hus\, the acceleration results.\n\nhttps://indico.ific.uv.es/event/2851/co ntributions/4205/ LOCATION:Facultad de Química (USC) Aula Química Orgánica URL:https://indico.ific.uv.es/event/2851/contributions/4205/ END:VEVENT BEGIN:VEVENT SUMMARY:Quantum Walking the number of quanta probability distribution DTSTART;VALUE=DATE-TIME:20170718T135500Z DTEND;VALUE=DATE-TIME:20170718T141500Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4204@indico.ific.uv.es DESCRIPTION:Speakers: Eugenio Roldán Serrano (Universitat de Valencia)\nW e present schemes based on the alternation between Jaynes-Cummings (JC) an d \nanti-JC Hamiltonians for implementing quantum walks along the number o f quanta "\nline"\, i.e.\, which provides new means for quantum state mani pulation\n\nhttps://indico.ific.uv.es/event/2851/contributions/4204/ LOCATION:Facultad Química (USC) Aula Química General URL:https://indico.ific.uv.es/event/2851/contributions/4204/ END:VEVENT BEGIN:VEVENT SUMMARY:Medida de vidas medias de estados excitados en los núcleos 136Te y 137Te en la campaña EXILL-FATIMA DTSTART;VALUE=DATE-TIME:20170719T141000Z DTEND;VALUE=DATE-TIME:20170719T142500Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4202@indico.ific.uv.es DESCRIPTION:Speakers: Victoria Vedia (Universidad Complutense Madrid (UCM) )\nEl estudio de núcleos exóticos ricos en neutrones en torno a los dobl emente mágicos 78Ni y 132Sn proporciona información relevante sobre las energías de partícula independiente así como de desarrollo de efectos c olectivos cerca de los cierres de capa nucleares. La investigación de est os núcleos exóticos puede clarificar las inesperadas modificaciones de l a estructura de capas que se produce en estas regiones\, y conocer en mejo r medida las interacciones efectivas entre nucleones\, así como la valida ción de modelos teóricos. En la región cercana al 132Sn los núcleos de telurio son una buena ejemplo\, puesto que poseen dos protones fuera del cierre de capas Z=50\, y su estructura puede ser explicada mediante el aco plamiento de una pareja de protones al 132Sn.\nLa colectividad del 136Te s e estudió por primera vez mediante reacciones de excitación coulombiana [1]\, obteniéndose una probabilidad reducida de transición B(E2\; 2+0 +) de 208(29) e2fm4. Este valor es mucho menor de lo esperado y no encaja con la sistemática de la zona\, en la que se espera un incremento progres ivo de las tasas de transición a medida que nos alejamos de N = 82. En es te caso el valor B(E2\; 2+0+) es muy similar al del 134Te (N=82) y adem ás los cálculos de modelo de capas tampoco lo reproducen con exactitud. Posteriores estudios de desintegración beta [2] midieron la vida media de l estado 2+ a través del la técnica ATD [3]\, proporcionando probabilida d reducida de transición B(E2\; 2+0+) = 250(50) e2fm4\, valor que enca ja mejor con la sistemática de la zona y con los cálculos teóricos. Por tanto se precisa de una clarificación de este valor para la transición 2+->0+ y\, si es posible\, ampliar las medidas de probabilidades reducidas a las transiciones E2 entre otros estados de la banda del estado fundamen tal.\nEn este trabajo presentamos la investigación de varios núcleos de Te ricos en neutrones mediante medidas de espectroscopia gamma y de coinci dencias ultrarrápidas. Los experimentos se realizaron en el ILL (Institut Laue-Langevin) de Grenoble Francia\, empleando el espectrómetro mixto EX ILL-FATIMA\, que es una estructura mixta de 8 clovers de Ge y 16 detectore s de LaBr3(Ce) [4]\, que aúna la buena resolución energética y eficienc ia de los detectores de germanio\, con la excelente resolución temporal d e los cristales centelleadores.

La enclatración de estas moléc ulas en el interior de las cavidades permite la formación del hidrato ya que la presencia del gas en su interior estabiliza la estructura del crist al. Las tres estructuras de hidratos más comunes son sI [1]\, sII [2] y s H [3]\, que difieren en el tamaño y el número de cavidades que forman la celdilla unidad de cada estructura cristalina macroscópica. El tipo de e structura del hidrato queda determinado principalmente por el tamaño de l a partícula invitada\, así como\, las interacciones entre la molécula i nvitada y las moléculas de agua que forman la estructura en su inmediato alrededor.\n\nLa simulación molecular en combinación con la técnica de coexistencia directa de fases se utilizó para predecir la línea de equil ibrio trifásico de los hidratos de dióxido de carbono en este trabajo[4] . Se realizaron simulaciones de dinámica molecular en el colectivo isoté rmico-isobárico para la determinación de la temperatura de coexistencia trifásica (T3) del sistema dióxido de carbono-agua a presiones en el int ervalo de 50-3000 bares.

Dose distribution disagreements between Monte Carlo (MC) and treatment planning system (TPS) calculations produce significant variations in the estimation of tumor control probabil ity (TCP) [2]. Hence for a complete treatment planification including radi obiological parameters we have to obtain an accurate calculation of the do se distribution.\n Our purpose is to assess radiobiological variation s of lung cancer treatment plans due to divergences between dose distribut ions calculated by Pinnacle³ TPS (version 9.8)\, employed at the Hospital Universitario Virgen Macarena (Seville\, Spain)\, and by the Geant4 MC to olkit (version 10.01.p01) [3\,4].\n\nMaterial and methods\n Three clin ical cases (see Table 1) distinguished by their tumoral size and localizat ion were analysed. Each clinical case presents a treatment planification c omposed by 6 MV photon beams with a conventional fractionation\, i. e. 2 G y per fraction. This scheme was established in order to achieve a 66 Gy pr escribed dose to the 95% of the planning target volume (PTV). We have set conformity index (CI) and homogeneity index (HI) [5] as key parameters for dose distribution comparisons between Pinnacle3 and Geant4. \n In ad dition to this dose analysis\, we have calculated TCP according to the lin eal-quadratic (LQ) model [6]. For this task we have used an alpha value of 0.3 Gy-1\, a beta value of 0.03 Gy-2 and a density of clonogenic cells of 10^7 cells/cm3. \n For TPS calculations we have applied the Collapse d Cone algorithm and a voxel resolution of 2 x 2 x 2 mm³. In our MC cal culations we have simulated 2•10^10 events per clinical case. The scorin g volume dimensions were equal to patient DICOM image files resolution\, i . e. 0.937 x 0.937 x 5 mm³. These files were exported from the TPS for ev ery single treatment plan.\n\nResults\n In Table 2 we have summarized the CI\, HI and TCP values calculated with Geant4 and Pinnacle3 for each clinical case. Furthermore\, we have obtained variations of absorbed dose at the 95% of the PTV (between Geant4 and TPS dose calculations) up to 2.3 Gy for the clinical case 1. In this case\, a gamma analysis [7] between c alculated dose distributions with Geant4 and TPS (Fig. 1)\, done with acce ptance criteria of 3%-3mm\, gave a passing rate of 78.3% within the patien t. This evaluation was done utilizing Monte Carlo Treatment Planning (MCTP ) CARMEN [8\,9].\n\nDiscusion and conclusions\n In all clinical cases we have found more heterogeneous dose distributions employing Geant4 as ca lculation system. HI and CI values show us that dose calculations depend o n the particular clinical case. For clinical case 1 we have done a gamma a nalysis (3%-3 mm)\, which shows high discrepancies (red points which do no t satisfied gamma criteria) at the dose maximum zone which is inside PTV. Dose divergences\, expressed through HI and CI values\, gave variations in TCP close to 4% between Geant4 and TPS calculations. In our methodology w e have used the LQ model with an alpha/beta ratio of 10 Gy and a constant clonogenic cells density of 10^7 cells/cm3. A further study including more sophisticated radiobiology models and hypofractionated radiotherapy schem es will is ongoing.\n\nAcknowledgments\n This work was funded in part b y the Spanish Ministry of Economy and Competitiveness (under projects no.

This question has been answered recently in the biparti te case\, while it is largely unexplored in the multipartite case\, with o nly a few scattered results\, using a variety of different methods: maxima l violation of a corresponding Bell inequality\, numerical SWAP method\, s tabilizer self-testing etc. This also explains why it is not clear which s tates can be self-tested. In our work\, we propose a unifying approach: co mbining projections to two-qubit spaces (projecting parties or degrees of freedom) and then using the maximal violation of tilted CHSH inequalities. In the qubit case\, using this simple but general approach\, we show that almost all multipartite qubit states can be self-tested (albeit with many measurements)\, namely all the ones that can be written with all real coe fficients in some basis. In particular\, this result is enough to characte rize the tripartite case completely. Moreover\, for special classes of mul tipartite states\, like symmetric Dicke states and graph states\, our appr oach yields a self-test with few measurements. Finally\, for the qudit cas e\, we show that all multipartite states which admit a Schmidt decompositi on can be self-tested with few measurements\n\nhttps://indico.ific.uv.es/e vent/2851/contributions/4194/ LOCATION:Facultad Química (USC) Aula Química General URL:https://indico.ific.uv.es/event/2851/contributions/4194/ END:VEVENT BEGIN:VEVENT SUMMARY:ALBA\, The Spanish synchrotron DTSTART;VALUE=DATE-TIME:20170721T082000Z DTEND;VALUE=DATE-TIME:20170721T091000Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4191@indico.ific.uv.es DESCRIPTION:Speakers: Caterina Biscari ()\nALBA history started in the fir st nineties\, when a group of visionary scientists proposed to build a syn chrotron light source in Spain\, as the first national large scientific in frastructure.

Finding routes to maximize the SHE is not po ssible as long as it remains unclear which is the dominant mechanism in a material. I will present a systematic study in Pt\, the prototypical SHE m aterial\, using the spin absorption method in lateral spin valve devices. We find a single intrinsic spin Hall conductivity in a wide range of condu ctivities\, in good agreement with theory. By tuning the conductivity\, we observe for the first time the crossover between the moderately dirty and the superclean scaling regimes of the SHE\, equivalent to that obtained f or the anomalous Hall effect. Our results explain the dispersion of values in the literature and find a route to maximize this important effect [3]. We also studied the mechanisms in Ta\, a material with a claimed giant SH E.

The nuclear symmetry energy represents the energy cost of changing protons in neutrons in symm etric nuclear matter. The symmetry energy can be estimated as a function o f the density as the difference between the energy per particle in pure ne utron matter and in symmetric nuclear matter. The behaviour of the symmetr y energy as a function of the density is basically ruled by the its slope respect to the density computed at saturation L. Although the symmetry ene rgy and its slope are not strictly observables\, many different experiment s have been devised to estimate these quantities using strong and electrom agnetic probes [1]. We will discuss here our predictions of the symmetry e nergy and its slope obtained from three different experiments. First\, we estimate the slope of the symmetry energy L from experimental data of the neutron skin thickness extracted from antiprotonic atoms [2-5]. Second\, w e discuss the ability of parity-violating elastic electron scattering at l ow momentum transfer to obtain information on the neutron skin thickness i n 208Pb and to constraint the density dependence of the nuclear symmetry e nergy [6-7]. Finally\, we compare the experimental electric dipole polariz ability obtained via polarized proton inelastic scattering at forward angl es in 208Pb\, 120Sn and 68Ni [8\,9] with the corresponding theoretical RPA calculations\, which allow to estimate the symmetry energy J and its slo pe L.\nAll these experiments provide different constraints on the slope L of the symmetry energy but the corresponding values have a considerable o verlap in a range around \, in reasonable agreement with other estimates t hat use different observables and methods to extract L. A global review ab out our work on these three topics can be found in Refs [10\,11].\nReferen cias\n[1]. Bao-An Li\, Xiao Han\, Phys. Lett. B727 (2013) 276.\n[2]. M. C entelles\, X. Roca-Maza\, X.

STO is a diamagnetic quantum paraelectric insulat or\, in which oxygen vacancies are typical anionic defects. Due to the don or character of the VO and the very large electron mobilities of these def ects\, even the slightest concentration of vacancies produces a measurable electrical conductivity. Thus\, the presence of VO plays a very important role in the transport properties of STO both in the form of thin films an d interfaces\, such as the well-studied STO/LaAlO3 interface [2]. Addition ally\, this heterostructures are subjected to epitaxial strain\, which has been shown a remarkable effect in the oxygen vacancy formation enthalpy. For this reason\, it is necessary to perform a systematic study of the VO formation energy in STO as a function of strain and understand the influen ce of these anionic defects in the transport properties of STO. Moreover\, the cationic defects\, namely strontium vacancies (VSr)\, also could play a crucial role in the structural properties of the STO thin films [3]\, p roducing a characteristic rotation pattern of the TiO6 octahedra to accomm odate the coherent epitaxial strain.\n\n In this work\, we present a co mplete thermodynamic study of VO formation in e-doped thin films grown by Pulsed Laser Deposition. Hall effect measurements confirmed that each VO i s doubly ionized and donates two electrons to the conduction band of STO. Furthermore\, our results demonstrate that both\, compressive and tensile strain\, leads to a decrease in the VO formation enthalpy\, in good agreem ent with the reported ab-initio calculations [4]. On the other hand\, we d etermined the existence of a different rotation pattern of the TiO6 octahe dra of the thin films under compressive or tensile strain\, which is relat ed with the unintentional presence of the strontium vacancies in the STO t hin films. \n Additionally\, we show the possibility to manipulate the oxygen vacancies by applying an external electric field with an Atomic For ce Microscopy tip. We demonstrate a change in the local volume and surface potential of the sample associated to the accumulation of oxygen vacancie s. The application of a negative (positive) voltage causes a local expansi on (contraction) in the surface of the sample about a half or one unit cel l height\, as can be observed in Figure 1. We also determine the diffusion coefficient of the Vo after removing the electric field as a function of strain\, proving that the mechanical effect is stable for hours as well as reversible [5].\n\nReferences\n[1] S.

For applications in spectroscopy and especially quantum in formation processing\, a major goal is to maximize the coupling strength g 1 of the atom to either electric or magnetic cavity fields\, making it lar ger than the decoherence rates of both the cavity and the atom (strong cou pling regime). Attaining this regime for individual spin qubits would open the possibility of developing an all-magnetic quantum processor [2]. This goal remains\, however\, very challenging because the interaction of each spin with the photon’s magnetic field is much weaker than the typical d ecoherence rates of the resonator and of most magnetic qubits. For this re ason\, strong coupling has been observed only in the case of macroscopic s pin ensembles\, containing N > 10^12 spins\, for which the effective colle ctive coupling gN is enhanced by a factor N^(1/2) with respect to that of a single spin [3\,4]. We have recently shown that the microwave magnetic f ield of a coplanar superconducting resonator can be enhanced locally via t he fabrication of nanoscopic constrictions at its central line [5]. In thi s communication\, we report the results of experiments performed on small spin ensembles directly deposited onto such constrictions.\n \n1.5 GHz sup erconducting resonators were fabricated by optical lithography on Nb layer s grown onto crystalline sapphire substrates. A typical design is shown in Fig. 1A. The width w of the central line can be reduced from the original 14 microns down to less than 50 nm by using a focused beam of Ga+ ions\, without appreciably altering the resonator characteristics (Figs. 1B and 1 C) [5]. Experiments were also performed using a w = 400 microns wide centr al line resonator. The magnetic samples consist of ensembles of DPPH free radicals\, each having a spin s = 1/2 with a fully isotropic gyromagnetic factor g = 2 and a negligibly small inhomogeneous broadening.6 Molecules w ere deposited onto the devices from a saturated solution in DMSO. For larg e ensembles on standard resonators\, the deposition was made using a micro pipette and the size of the spin ensemble varied by controlling the drople t volume. Smaller spin ensembles were deposited using dip-pen nanolithogra phy.7 The tip of an atomic force microscope (AFM) is used to write small d ots (between 5 and 60 microns wide) with a very high spatial resolution. T he number of spins N lying inside the area of the constriction was accurat ely determined from Scanning Electron Microscopy and AFM experiments (Fig 1D). \nThe transmission S21 of microwave radiation trough the resonators w as measured at T = 4.2 K as a function of magnetic field and frequency ome ga. The maximum transmission\, near the ground mode at omega/2pi = 1.5 GHz \, and the effective Q factor decrease sharply when the field brings the s pins into resonance with the circuit. From these experiments\, the collect ive coupling constant has been determined for samples with N varying betwe en 10^8 and 10^16 spins. The results (Fig. 1 E) show that gN is proportion al to N^(1/2) both for the original resonators and for the constrictions. However\, the average coupling to each spin g1 = gN/N^(1/2)\, is enhanced by more than two orders of magnitude (from 0.25 Hz up to 50 Hz) in the lat ter case. As a result\, magnetic ensembles\, e.g. a 30 microns drop\, that are completely undetectable with a conventional resonator become visible when they are deposited near a superconducting nano-bridge. Furthermore\, the dependence of g1 on the width of the central line agrees quantitativel y with theoretical predictions (Fig. 1 F) [8].\nThese results show that th e coupling of spin qubits to quantum superconducting circuits can be enhan ced via a combination of top-down and bottom up nanolithography techniques . In the present experiments\, the spin-photon coupling remains in the wea k coupling regime because DPPH shows decoherence rates 1/T2 > 12 MHz. The strong coupling regime might\, however\, be attained for especially design ed molecular spin qubits that can show 1/T2 values as small as 1 kHz [9]. Furthermore\, reaching this limit for individual spins\, a pre-requisite f or the development of a magnetic quantum processor\, will then also be fea sible provided that nanofabrication techniques are pushed down to w \n\nht tps://indico.ific.uv.es/event/2851/contributions/4154/ LOCATION:Facultad de Química (USC) Aula Química Inorgánica URL:https://indico.ific.uv.es/event/2851/contributions/4154/ END:VEVENT BEGIN:VEVENT SUMMARY:Photonic analogs of wave-like dark matter DTSTART;VALUE=DATE-TIME:20170719T143500Z DTEND;VALUE=DATE-TIME:20170719T145500Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4153@indico.ific.uv.es DESCRIPTION:Speakers: Angel Paredes Galan (Universidade de Vigo)\nWe point out formal connections between the astrophysical dynamics of dark matter and the propagation of laser beams in thermooptical media.

The ground state correspo nds to maximum spin projections Sz = +10 and -10 along the anisotropy axis \, common to all molecules\, which define the ‘0’ and ‘1’ bit stat es (Fig. 1(a)). These states are separated by an energy barrier U/kB ≈ 2 4 K\, which hinders the spin flip and gives rise to magnetic hysteresis\, thus magnetic memory\, below approximately 1.2 K [5\,6].\n \nIn our experi ments\, the Landauer cycle is performed\, at T = 1 K\, via the application of a sequence of magnetic fields aligned along different orientations wit h respect to the magnetic anisotropy axis (Fig. 1(b)). The erasure is indu ced by a transverse magnetic field Hy\, which reduces the height of the ma gnetic energy barrier and promotes tunneling between quasi-degenerate spin projections\, thus exploiting a form of quantum annealing [7\,8]. The bit s are then recorded by applying a magnetic field Hz along the anisotropy a xis\, strong enough to polarize their magnetic moments. The cycle is then completed by reducing first Hy and then Hz back to zero. \nThe magnetic su sceptibility along z and y has been measured (Fig. 1(c)) and then integrat ed to obtain the net magnetic work required to perform the erasure and rec ording cycle. It agrees\, within experimental uncertainties\, with the Lan dauer limit. The ac susceptibility provides also information about the mag netization dynamics and\, in particular\, enables us to estimate the time needed to record each bit. This time turns out to be shorter than 0.1 micr o-seconds thanks to the very fast quantum spin dynamics induced by the tra nsverse magnetic field. The performance of our device in terms of energy-t ime cost is then orders of magnitude better than that of any existing memo ry devices to date.\nAcknowledgments\nThe research reported here was suppo rted by the Spanish MINECO (grant MAT2015-68204-R)\, the Dutch Organizatio n for Fundamental research (NWO/FOM)\, the Gobierno de Aragón (grant E98- MOLCHIP) and the European Union (advanced ERC grant Mols@Mols and COST 151 28 Molecular Spintronics project). \nReferences\n[1] R.

La técnica más sensible\, i.e.\, la única que permite detectar un único ion confinado en la trampa\, es la de corr ientes inducidas (IIC)\, donde la detección se realiza utilizando circuit os LC o SQUIDs -resonantes con alguna de las frecuencias propias de movimi ento del ion en la trampa-. Las medidas de masa más precisas se han lleva do a cabo en experimentos donde se emplea la técnica IIC con iones que ti enen una relación masa-carga baja o intermedia [3]\, pero aún no se ha m ostrado su aplicabilidad con los elementos superpesados (Z ≥ 104) [4]. \ n\nCon el objetivo de poder medir la masa de elementos de interés en esta zona de la carta de núcleos\, se ha propuesto un método alternativo de detección [5] que actualmente se encuentra en desarrollo en el Laboratori o de Trampas de Iones de la Universidad de Granada. El proyecto TRAPSENSOR se basa en sustituir el sistema de detección electrónica por un ion de 40Ca+ enfriado por láser\, que actúa como sensor óptico. Esta detecció n óptica consiste en la monitorización de la amplitud del movimiento axi al del ion de 40Ca+ a partir de la recolección de los fotones de fluoresc encia emitidos por el mismo. El ion cuya masa queremos medir y el ion sens or están conectados mediante un electrodo común que permite acoplar sus movimientos a través de las corrientes inducidas en el mismo. Esta idea\, inicialmente propuesta en la Ref. [6]\, se ha llevado a cabo acoplando do s especies iónicas en una misma trampa a través de la interacción de Co ulomb entre los dos iones confinados en el mismo pozo de potencial [7] o e n pozos de potencial distintos [8]\, previamente enfriados hasta el mismo estado cero de energía. Sin embargo\, todavía no se han acoplado dos ion es confinados en trampas distintas. En la Universidad de Granada\, el obje tivo final es este acoplamiento en un sistema de dos microtrampas (descrit o y caracterizado en la Ref. [9]) en el seno de un campo magnético de 7 T .\n\nComo paso previo al acoplamiento\, se ha caracterizado el ion de 40Ca + como sensor de señales eléctricas midiéndose la variación de la señ al de fluorescencia del ion confinado en una trampa de radiofrecuencia con simetría rotacional [10] al aplicar un campo eléctrico dipolar oscilant e\, tratando de simular el efecto producido por un ion en una trampa conti gua. Este estudio en la trampa de radiofrecuencia nos permite estimar la s ensibilidad del sistema final a la excitación mediante campos eléctricos . En la Fig.1 se muestran las imágenes de fluorescencia obtenidas para do s casos particulares: en ausencia de excitación y cuando se aplica un cam po eléctrico dipolar cercano a la frecuencia del movimiento axial del ion en la trampa. En ausencia de excitación\, la proyección de la imagen de fluorescencia en el plano axial resulta en una distribución gaussiana co n una desviación típica de 3 μm\, de la que es posible inferir la tempe ratura axial del ion en el límite Doppler usando el Teorema de equipartic ión [11]. Para una excitación continua y en presencia de los láseres de enfriamiento\, el ion alcanza un estado estacionario que consiste en una oscilación amortiguada y forzada de amplitud constante\, cercana a 20 μm . \n\nPara caracterizar la sensibilidad del ion de 40Ca+ a señales eléct ricas aplicadas\, tales como las generadas por un ion\, hemos estudiado la amplitud de oscilación en el estado estacionario del ion en función de la frecuencia del campo aplicado [12]. En esta contribución presentaremos los resultados obtenidos y las mejoras previstas a corto y medio plazo. U no de los objetivos a medio plazo es mejorar las prestaciones del sistema óptico que permitan mejorar la sensibilidad y reducir la temperatura del ion añadiendo otro mecanismo de enfriamiento. En paralelo se investigará el enfriamiento del ion en una trampa Penning de 7 T.\n\nFigura 1. Imáge nes de fluorescencia del ion para los casos sin campo externo aplicado (iz quierda) y aplicando un campo dipolar resonante con el movimiento del ion (derecha). Las imágenes se han adquirido a través de una cámara EMCCD y un sistema óptico que permite una magnificación de un factor 7.\n\nEste proyecto está financiado por el Consejo Europeo de Investigación (ERC S tG 278648-TRAPSENSOR) junto con los proyectos MINECO/FEDER FPA2012-32076\, FPA2015-67694-P\, UNGR10-1E-501\, FIS2015-69983-P\, UNGR13-1E-1830 y Junt a de Andalucía/FEDER IE_57131.

Identificati on and characterization of these degradation products has always been of h igh importance because it is the first step to develop and apply the appro priate treatments to preserve our cultural heritage.\n The concern is more acute for modern and contemporary art\, because the materials used are so radically different from those used in classical art\, that there is a si gnificant lack of established conservation protocols that can deal with th e often extremely fast degradation of materials used by contemporary artis ts. \nIn this work we show our approach to detect early degradation produc ts of common polymers by means of surface enhanced Raman scattering (SERS) sensors developed in our lab\, and based on the fabrication of regular mi cro and nanostructured polymers coated with a thin layer of aluminum as pl asmonic metal.\nChecking the health of artworks by SERS\nRaman spectroscop y is a nondestructive method that provides the vibrational fingerprint spe ctrum of the molecular structure of materials\, so it might be the perfect tool to analyze artworks where the sampling is highly restricted. But Ram an signal is intrinsically weak due to the low number of scattered photons available for detection. \nSurface Enhanced Raman Scattering (SERS) comes to help\, because it is a method to amplify the Raman signals of molecule s by an increment of their apparent Raman cross-section [1]. To do this tr ick\, the excitation laser is shined over metallic nanoparticles or nano-s tructured metal surfaces\, typically made of noble metals\, with gold and silver as common choice. The laser resonantly drives the metal surface cha rges\, creating highly localized plasmonic light fields\, known as hot-spo ts. When a molecule is close to one of these hot-spots\, a large amplifica tion of its Raman signal can be observed\, allowing the detection of very low concentrations of chemical species or even single molecule detection [ 2]. \nThe main problem to use SERS as everyday lab technique is the lack o f appropriate substrates. Few commercial substrates are available\, they a re expensive and quite unstable\, requiring to keep them in controlled atm ospheres and careful handling to maintain their enhancing activity. Anothe r problem is repeatability due to variability in size and distribution of nanostructures.\nTo tackle the main drawbacks of SERS substrates we develo ped an easy and cheap fabrication process in just two steps: replica moldi ng based on ultraviolet nanoimprint lithography (UV-NIL)\, followed by coa ting with a thin metal layer by metal evaporation. The molding step guaran tees the same shape and structure in all the substrates and the UV-NIL pro vides freedom to design any 2.5D structure and\, in combination with the p hotoresist used\, reduces the fabrication time to just a few seconds. In o ur case we choose a crosslinkable di- or tetrafunctional perfluoropolyethe r derivate [3] and a commercial ormocer photoresist. \nAs plasmonic metal we relies on aluminium\, initially because its low cost compared to gold o r silver and also because the Al2O3 passivation layer\, that far from bein g a problem is an advantage because after reaching a thickness of 1.5 to 3 .0 nm it stops growing and protect the metal from further oxidation\, whil e still allows the plasmonic excitation of molecules attached to the surfa ce. Aluminium has properties that enable strong plasmon resonances spannin g from the UV to the NIR region [4].\n \n\nFig.1. Polymer and Al SERS substrates and SEM image of the periodic nanostructure showing the inverte d pyramids geometry and the nanocrystals of Al on the surface. \n\nInitial tests where made with organic analytes like Rhodamine 6G\, Coumarin 440\, Rhodamine B or Crystal Violet\, using 514 nm and 785 nm excitation lasers with powers ranging between 0.01-1.0 mW. The signal enhancement is compar able or higher than that obtained with commercial substrates made of gold or silver. \n \nFig.2. SERS spectra of photo-o xidation products of: a) linseed oil and b) polyisoprene rubber.\n\nAs an actual application we are testing the SERS substrates to detect and identi fy early degradation products formed by ageing or weathering of modern and contemporary artworks made of different polymers and blends. This diagnos tic information is relevant for material science researchers and conservat ors which can develop and apply appropriate treatments to fight against de gradation and preserve valuable cultural heritage goods. The sensibility of SERS substrates is a keystone in a field where sampling is strongly lim ited due to the value of the pieces. Tests on different polymers\, binder s\, inks\, pigments and other materials are yielding promising results tho se showed in Fig.1b.\n\nThis work was supported by the European Union (COR DIS) Project NANORESTART (H2020-NMP-21-2014/646063).

Comuñas (Universidad de Santiago de Com postela)\nLos estudios sobre la estructura y propiedades de las nanopartí culas y los nanofluidos han revolucionado diferentes campos de investigaci ón tales como Química-Física\, Nanotecnología o Ciencia de materiales\ , y han permitido desarrollar importantes aplicaciones en la industria\, la medicina y la biología. En el caso de los nanofluidos de transferencia térmica y los de almacenamiento térmico se han realizado ya grandes ava nces. Existeuna red europea que fomenta el uso de estos materiales analiza ndo su eficiencia con el fin de que puedan usarse comercialmente [1]. Otra aplicación de los nanoaditivos en el sector de las energías renovables y uso eficiente de la energía es la de los nanolubricantes. Hay muchos ti pos diferentes de nanomateriales con propiedades antifricción y antidesga ste potencialmente interesantes [2]. Los parámetros críticos que influye n en las propiedades tribológicas de los sistemas lubricados a base de na nopartículas son su tamaño\, forma y estructura así como la concentraci ón de las mismas. \nLas investigaciones sobre el uso específico de nanol ubricantes en aerogeneradores son muy escasas. Debemos señalar el estudio llevado a cabo por Greco et al. [3] en el que usa una polialolefina aditi vada con nanopartículas de nitruro de boro y varios aceros de engranajes con diferentes tratamientos superficiales. Debido a las reacciones triboqu ímicas entre la superficie y el aditivo del lubricante\, se obtienen los mejores resultados con las superficies endurecidas por borización. Existe n estudios más generales del efecto de las nanopartículas en lubricació n en régimen elastohidrodinámico (EHL)\, que tiene lugar en engranajes d e multiplicadores y en los sistemas de transmisión que se usan en automoc ión. Ghaednia et al. [4] encontraron buenos resultados con nanopartícula s de plata con un tamaño medio de 7 nm en un polietilenglicol (PEG). Mosl esh and Shirvani [5] concluyeron que algunos nanolubricantes que contienen nanopartículas de diamante en un aceite de motor\, reducen la rugosidad de la superficie de contacto bajo régimen EHL lo cual implica un aumento en la relación de espesor de película y por tanto una menor fuerza de f ricción.\nLos estudios asociados con el uso de nanolubricantes como aceit es de motores son muy escasos. Shenderova et al. [6] estudiaron las sinerg ias entre nanoparticulas de diamante\, de teflón y de dialquilditiofosfat o de molibdeno en polialfaolifenas y otros aceites. Los tests tribológico s específicos para aceites de motores mostraron reducciones de la fricci ón desde modestas a significativas dependiendo de las combinaciones de ad itivos y aceite. Por ejemplo\, el uso de nanodiamantes disminuyó en un 35 % las huellas de desgaste.\n\nhttps://indico.ific.uv.es/event/2851/contrib utions/4127/ LOCATION:Facultad Química (USC) Aula Químca Orgánica URL:https://indico.ific.uv.es/event/2851/contributions/4127/ END:VEVENT BEGIN:VEVENT SUMMARY:Measuring Majorana non-locality and spin structure with a quantum dot DTSTART;VALUE=DATE-TIME:20170719T142500Z DTEND;VALUE=DATE-TIME:20170719T144500Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4114@indico.ific.uv.es DESCRIPTION:Speakers: Elsa Prada (Universidad Autónoma de Madrid)\nRobust zero bias transport anomalies in semiconducting nanowires with proximity- induced superconductivity have been convincingly demonstrated in various e xperiments. While these are compatible with the existence of Majorana zero modes at the ends of the nanowire\, a direct proof of their non-locality and topological protection is now needed. Here we show that a quantum dot at the end of the nanowire may be used as a powerful spectroscopic tool to quantify the degree of Majorana non-locality through a local transport me asurement. Moreover\, the spin polarization of dot sub-gap states at singl et-doublet transitions in the Coulomb blockade regime allows the dot to di rectly probe the spin structure of the Majorana wavefunction\, and indirec tly measure the spin-orbit coupling of the nanowire.\n\nhttps://indico.ifi c.uv.es/event/2851/contributions/4114/ LOCATION:Facultad de Química (USC) Aula Química Inorgánica URL:https://indico.ific.uv.es/event/2851/contributions/4114/ END:VEVENT BEGIN:VEVENT SUMMARY:Zero-energy pinning from interactions in Majorana nanowires DTSTART;VALUE=DATE-TIME:20170719T140500Z DTEND;VALUE=DATE-TIME:20170719T142500Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4113@indico.ific.uv.es DESCRIPTION:Speakers: Pablo San-Jose (ICMM-CSIC)\nMajorana zero modes at t he boundaries of topological superconductors are charge-neutral\, an equal superposition of electrons and holes. This ideal situation is\, however\, hard to achieve in physical implementations\, such as proximitised semico nducting nanowires of realistic length. In such systems Majorana overlaps are unavoidable and lead to their hybridisation into charged Bogoliubov qu asiparticles of finite energy which\, unlike true zero modes\, are affecte d by electronic interactions. We here demonstrate that these interactions\ , particularly with bound charges in the dielectric surroundings\, drastic ally change the non-interacting paradigm. Remarkably\, interactions may co mpletely suppress Majorana hybridisation around parity crossings\, where t he total charge in the nanowire changes. This effect\, dubbed zero-energy pinning\, stabilises Majoranas back to zero energy and charge\, and leads to electronically incompressible parameter regions wherein Majoranas rema in insensitive to local perturbations\, despite their overlap.\n\nhttps:// indico.ific.uv.es/event/2851/contributions/4113/ LOCATION:Facultad de Química (USC) Aula Química Inorgánica URL:https://indico.ific.uv.es/event/2851/contributions/4113/ END:VEVENT BEGIN:VEVENT SUMMARY:Asamblea General GEEF DTSTART;VALUE=DATE-TIME:20170718T170000Z DTEND;VALUE=DATE-TIME:20170718T180000Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4110@indico.ific.uv.es DESCRIPTION:Speakers: Verónica TRICIO (Presidenta GEEG)\nhttps://indico.i fic.uv.es/event/2851/contributions/4110/ LOCATION:Facultad Química (USC) Aula Biología URL:https://indico.ific.uv.es/event/2851/contributions/4110/ END:VEVENT BEGIN:VEVENT SUMMARY:Las olimpiadas de física: Preparación de alumnos y Pruebas exp erimentales DTSTART;VALUE=DATE-TIME:20170718T143000Z DTEND;VALUE=DATE-TIME:20170718T150000Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4107@indico.ific.uv.es DESCRIPTION:Speakers: Carmen Cabanas (IES Eusebio de la Guarda)\, Óscar C abeza (Universidade de A Coruña)\nLas olimpiadas de física: Preparación de alumnos\n\nhttps://indico.ific.uv.es/event/2851/contributions/4107/ LOCATION:Facultad Química (USC) Aula Biología URL:https://indico.ific.uv.es/event/2851/contributions/4107/ END:VEVENT BEGIN:VEVENT SUMMARY:Estudio de propiedades microscópicas de plasmas de experimentos d e astrofísica de laboratorio DTSTART;VALUE=DATE-TIME:20170718T164000Z DTEND;VALUE=DATE-TIME:20170718T170000Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4473@indico.ific.uv.es DESCRIPTION:Speakers: Guadalupe Espinosa (Universidad de Las Palmas de Gra n Canaria)\nLa Astrofísica de Laboratorio (AL) es un tópico de investiga ción dentro del campo de la física de alta densidad de energía que ha v enido ganando importancia en las dos últimas décadas\, siendo en la actu alidad un área que atrae mucha atención. El campo de la AL abarca el est udio teórico y experimental de la física que subyace bajo ciertos fenóm enos físicos observados en el cosmos\, en un régimen susceptible de pres entarse en un laboratorio\, evitando los inconvenientes que el análisis o bservacional suele presentar\, tales como la distancia entre el observador y el fenómeno de estudio\, las limitaciones tecnológicas\, la imposibil idad de acceder al fenómeno en varias ocasiones\, de repetirlo\, o la imp osibilidad de controlar las condiciones bajo las cuales se producen dichos fenómenos. En este sentido\, la AL\, que permite la cercanía al fenóme no y la capacidad de controlarlo y repetirlo\, ha abierto un nuevo camino que usan los astrofísicos\, y que une a físicos experimentales y teóric os en la investigación del Universo\, ofreciendo además nuevos puntos de vista en los procesos de interpretación de los datos observacionales y d e las teorías actuales sostenidas por la Astrofísica Moderna. Además\, los experimentos realizados en el contexto de la AL proporcionan datos par a la verificación y la validación de diversos aspectos de los códigos n uméricos tales como la física atómica\, la hidrodinámica\, las ecuacio nes de estado y la transferencia radiativa\, códigos que se emplean en di versos campos de la física de alta densidad de energía.\nDos han sido lo s desarrollos que han contribuido al diseño exitoso de experimentos de AL . El primero es que se ha comprobado que la hidrodinámica puede ser escal ada correctamente entre los escenarios astrofísicos y el laboratorio. Est e hecho fue presentado por primera vez en el trabajo pionero de Ryutov et al. para un escenario astrofísico concreto (remanentes de supernova). Des de entonces\, las condiciones que han de verificarse para un correcto esca lado de un fenómeno astrofísico en laboratorio han sido extendidas a esc enarios más complejos\, incluyendo campos magnéticos o campos de radiaci ón intensos.\nEl segundo desarrollo ha sido el empleo de láseres intenso s y dispositivos de potencia pulsada\, pensados inicialmente para otros ca mpos de la alta densidad de energía como la fusión por confinamiento ine rcial\, para conseguir las condiciones necesarias para los experimentos de AL\, ya que permiten colocar a la materia en estados extremos de temperat ura\, densidad y velocidad.\nComo se comentó anteriormente\, los datos qu e proporcionan los experimento de AL son muy valiosos para verificar y val idar los modelos teóricos y computacionales habitualmente empleados en la física de alta densidad de energía. En la bibliografía es común encon trar simulaciones hidrodinámicas (y\, por tanto\, macroscópicas) de los experimentos de AL\, detectándose un vacío en el estudio\, análisis y d eterminación de las propiedades microscópicas en el correcto estado term odinámico de los mismos (tales como ionizaciones medias\, distribuciones iónicas\, la cinética de poblaciones o las propiedades radiativas) de lo s plasmas generados en dichos experimentos. Sin embargo\, este estudio mic roscópico es fundamental ya que muchas de estas propiedades microscópica s son necesarias para las simulaciones hidrodinámicas (opacidades e ioniz aciones medias y pérdidas de potencia radiativas\, entre otras\, que muy comúnmente son calculadas en esas simulaciones con modelos atómicos senc illos o con modelos de cinética atómica simplificados basados en suponer al plasma en equilibrio Corona o equilibrio termodinámico local\, ETL\, aunque no se verifiquen las condiciones de los mismos)\, para la transfere ncia radiativa y para la diagnosis espectroscópica de las condiciones del plasma. Además\, estos estudios microscópicos permiten conocer también la importancia de los efectos de reabsorción de la radiación (plasma gr ueso o delgado)\, de la estacionariedad o no del plasma\, de los campos de radiación externos (plasmas fotoionizados)\, del régimen termodinámico del plasma (ETL o NETL) o de la presencia de diferentes elementos en el p lasma (plasma multicomponente).\nEste trabajo se enmarca dentro de ese con texto. Debido a nuestra participación como grupo teórico en varios exper imentos de AL en el último lustro\, hemos realizado análisis microscópi cos de los plasmas que se generan en los mismos\, con el fin de ilustrar l os efectos anteriormente comentados en dichos experimentos y así servir d e ayuda en las simulaciones hidrodinámicas posteriores\, además de propo rcionar información acerca de lo que ocurre microscópicamente en dichos experimentos. Con el fin de mostrar los estudios realizados\, hemos selecc ionado dos experimentos en particular. En el primero\, se analizaron las o ndas de choque radiativas generadas en laboratorio a través de la absorci ón de un láser intenso por un cluster de átomos de xenón o kriptón\, las cuales emulaban las que se observan en los remanentes de supernova. En el segundo\, se estudió las propiedades microscópicas de un jet de alum inio que se generaba en un dispositivo de potencia pulsada y de las ondas de choque que se creaban en la propagación de dicho jet en argón. El obj etivo de este experimento era la reproducción en laboratorio de los jets que se generan en la formación de estrellas jóvenes y la interacción de los mismos con el medio interestelar. En ambos experimentos analizamos\, también\, de forma teórica la posibilidad de la aparición de inestabili dades térmicas por enfriamiento radiativo del plasma chocado que se encue ntra justo detrás del frente de las ondas de choque radiativas generadas en esos experimentos. El estudio de dichas inestabilidades se hace comúnm ente a través de la parametrización del coeficiente de enfriamiento. En nuestro estudio\, dicha parametrización se realiza en función de la dens idad y de la temperatura usando el código PARPRA y no solo de la densidad \, como es común encontrarla en la bibliografía\, ya que el plasma en lo s experimentos de AL se encuentra\, en general\, en NETL y la contribució n más relevante a la emisión de radiación es la de transición de líne a\, a diferencia de los fenómenos astrofísicos que se emulan.\nPara nues tro estudio teórico empleamos nuestros códigos para el cálculo de la ci nética de poblaciones\, MIXKIP [7]\, y de propiedades radiativas\, RAPCAL [8]. Estos códigos permiten el cálculo de las poblaciones de nivel de l os plasmas y las propiedades radiativas para plasmas mono y multicomponent es\, en estado estacionario o no\, delgados o gruesos\, de número atómic o alto\, medio y bajo\, en ETL y NETL e incluyendo campos de radiación ex ternos.\n\nhttps://indico.ific.uv.es/event/2851/contributions/4473/ LOCATION:Facultad de Química (USC) Aula Química Analítica URL:https://indico.ific.uv.es/event/2851/contributions/4473/ END:VEVENT BEGIN:VEVENT SUMMARY:Recuperación de datos meteorológicos en Extremadura: primeros re sultados DTSTART;VALUE=DATE-TIME:20170717T140000Z DTEND;VALUE=DATE-TIME:20170717T141500Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4472@indico.ific.uv.es DESCRIPTION:Speakers: José Manuel Vaquero (Universidad de Extremadura)\nA excepción de los estudios sobre el clima de la región de Zafra desde 17 50 hasta 1840 utilizando descripciones semanales del tiempo atmosférico q ue ha realizado nuestro grupo de investigación [1-3]\, la reconstrucción del clima en Extremadura en los últimos siglos haciendo este tipo de eje rcicios está\, simplemente\, por hacer. Además\, a día de hoy\, los arc hivos y bibliotecas de Extremadura no han sido consultados sistemáticamen te para extraer de ellos informaciones relevantes sobre el clima del pasad o. Nuestro equipo de investigación ha realizado algunas exploraciones pre vias que revelan que los archivos extremeños tienen un enorme potencial e n este sentido\, especialmente en la recuperación de datos. Los primeros datos meteorológicos localizados de Extremadura fueron tomados en Zafra ( Badajoz) en la década de 1820. En la ciudad de Badajoz\, disponemos de da tos meteorológicos diarios desde 1830 a 1833\, publicados en la prensa lo cal [4]. En la provincia de Cáceres\, los primeros datos que hemos locali zado son de 1844\, publicados en un periódico de la capital cacereña. Ta mbién contamos con la estación meteorológica de Badajoz\, en funcionami ento ininterrumpido desde 1860. De cara a los estudios de homogeneización de los datos de Badajoz\, merece la pena destacar que contamos con una es tación portuguesa cercana (la estación de Campo Mayor a tan sólo 15 km de distancia) desde 1861. Además\, también se tomaron datos meteorológi cos de una manera regular durante gran parte del siglo XIX en los balneari os de Baños de Montemayor (Cáceres) y de Alange (Badajoz). Y podemos inc luso citar que la provincia de Badajoz contó con la primera red meteorol ógica española privada [5]. Todo esto nos indica que la región de Extre madura tiene un enorme potencial para actividades de recuperación de dato s meteorológicos de los siglos XIX y XX.\n¿Es posible extender en el tie mpo las series meteorológicas de Badajoz y Cáceres? La agencia estatal A EMET proporciona valores diarios de las principales variables meteorológi cas desde 1901 y 1907 para Badajoz y Cáceres respectivamente. No obstante \, también proporciona valores mensuales anteriores para la serie de Bada joz. En la biblioteca de la delegación territorial de AEMET-Extremadura ( en el campus universitario de Badajoz)\, se encuentran los libros original es manuscritos de las estaciones de Badajoz y Cáceres. Los dos primeros l ibros de observaciones de Badajoz contienen los datos diarios desde 1864 h asta 1900. Obviamente\, aparecen numerosas variables meteorológicas. Por lo tanto\, es factible obtener datos diarios a partir de esta fuente desde el año 1864\, aunque con algunas importantes lagunas. Podemos indicar ta mbién que hay varios pliegos sin encuadernar de la estación meteorológi ca de Valdesevilla (aproximadamente de la década de 1880).\n¿Es posible encontrar datos diarios para rellenar los huecos mencionados? Creemos que se pueden recuperar con cierta facilidad datos meteorológicos diarios ext remeños del siglo XIX a partir de los números de la “Gaceta de Madrid ”\, principalmente de la década de 1880 (con datos de las estaciones de Badajoz\, Cáceres y Valdesevilla). Los primeros datos meteorológicos ex tremeños que hemos encontrado en la “Gaceta de Madrid” son los de Bad ajoz\, que comienzan a publicarse el 1 de noviembre de 1864. A partir del 25 de octubre de 1880\, también hay datos de Cáceres (que acaban aproxim adamente en 1889). También hay datos de la estación de Valdesevilla en e sa década. En general\, se publican datos del día anterior de presión\, temperatura\, dirección e intensidad del viento y estado de la atmósfer a tomados a las 9 horas (se supone que en tiempo local).\nHemos detectado unos (pocos) periódicos extremeños con datos meteorológicos del siglo X IX. Una búsqueda exhaustiva de éstos llevaría bastante tiempo. Estos pe riódicos son: “Boletín de la Agencia de Cáceres”\, “Boletín-Revi sta del Instituto de Badajoz”\, “Diario de Badajoz”\, “Diario de C áceres”\, “El Avisador de Badajoz”\, “El Iris” y “El Oliventi no”. También merece destacarse la publicación “Revista de Extremadur a”\, donde hay comparaciones de datos simultáneos medidos en Badajoz y en Cáceres\, así como datos mensuales de una estación colocada en el pa tio de una casa de Cáceres. Además\, contamos con otras fuentes. En los resúmenes de observaciones del Observatorio de Madrid (o del organismo co mpetente de la época) pueden encontrarse datos meteorológicos de Extrema dura del siglo XIX (al menos\, de Badajoz\, Cáceres\, Don Benito y Valdes evilla). Lamentablemente\, estos resúmenes tan sólo contienen datos mens uales.\nDentro de este ambicioso trabajo de recuperación de datos meteoro lógicos de Extremadura\, hemos comenzado a dar los primeros pasos\, que s erán brevemente mencionados aquí:\na) Recuperación de los datos meteoro lógicos del antiguo aeródromo de “Las Bardocas”. Hay documentación de archivo que atestigua su funcionamiento a partir de los años 1920. Se vislumbra en esta documentación que dicha infraestructura se trasladó a las actuales instalaciones de la Base Aérea de Badajoz-Talavera la Real\, pues el terreno en el que se situó el aeródromo de “Las Bardocas” e ra una zona inundable. Asociado a dicho aeródromo\, situado a 3 km del ce ntro urbano de la ciudad de Badajoz\, había un observatorio meteorológic o (-6º 56’ 27’’ W y 38º 54’ 15’’ N). Se han realizado trabaj os que han permitido el hallazgo de los cuadernos de observación original es y el rescate de los datos meteorológicos\, registrados en el observato rio del Aeródromo de Badajoz “Las Bardocas”\, durante los años 1948- 1954. Se ha realizado también un análisis preliminar de los mismos.\nLas variables cuyos datos se han recuperado hasta la fecha son temperatura ob servada cada tres horas\, temperaturas extremas diarias\, humedad\, precip itación\, presión y viento\, resultando de los primeros análisis que di chos datos son climatológicamente coherentes con los de los observatorios de Badajoz\, y de la Base Aérea de Badajoz-Talavera la Real (las observa ciones en esta nueva instalación aérea comienzan en 1955).\nPrimero\, se organizaron y clasificaron los documentos estructurados en libros por añ os y meses. Después\, se escanearon para conservarlos en formato imagen ( .JPG) en soporte digital. Y\, más tarde\, se digitalizaron los valores nu méricos en ficheros Excel.\nb) Recuperación de datos diarios de insolaci ón en Badajoz desde septiembre de 1928. Hemos iniciado la recuperación d e esta serie de insolación de casi 90 años\, de carácter excepcional en el marco de los datos de insolación en España [6]. Los resultados previ os indican que la serie no tiene huecos importantes.\nc) Recuperación de datos de sondeos aerológicos. En 1924\, comenzaron en el observatorio de Badajoz la observación de vientos en altura mediante el seguimiento de gl obos piloto. Se han localizado los cuadernos de observación originales de los años 1924 a 1953 y se ha documentado el método de observación. Se sabe que las observaciones continuaron hasta 1970\, al menos. Sin embargo\ , lamentablemente\, de los años posteriores sólo se han encontrado\, has ta el momento\, resúmenes hasta 1960.\nd) Recuperación de datos actinom étricos de Cáceres. Se han encontrado datos diarios actinométricos de l a Estación Meteorológica de Cáceres (con algunos huecos) medidos con un actinómetro de Arago en el período 1913-1923. Se está trabajando con e sta serie de medidas actinométricas para hacer un estudio estadístico-cl imatológico de los datos.\nEste trabajo ha sido parcialmente financiado p or la Junta de Extremadura (GR15137) y por el Ministerio de Economía y Co mpetitividad del Gobierno Español (AYA2014-57556-P).\nReferencias\n[1] M.

The procedure employs a kinetic master equation (MEQ) which describes the time evolution of the rotational populations of O2 along three supersonic jets of O2 + He mixtures. The MEQ is expressed in terms of experimental quantities (number density and rotational populations)\, and calculated ra te coefficients for the O2:He and O2:O2 inelastic collisions from the lite rature. By scaling these rate coefficients\, a satisfactory agreement with the experiments is accomplished for temperatures between 10 and 34 K.\n\n https://indico.ific.uv.es/event/2851/contributions/4470/ LOCATION:Facultad de Química (USC) Aula Matemáticas URL:https://indico.ific.uv.es/event/2851/contributions/4470/ END:VEVENT BEGIN:VEVENT SUMMARY:Preliminary Results on 64Se beta decay experiment at RIKEN Nishina Center DTSTART;VALUE=DATE-TIME:20170719T135500Z DTEND;VALUE=DATE-TIME:20170719T141000Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4468@indico.ific.uv.es DESCRIPTION:Speakers: Pablo Aguilera (Instituto de Física Corpuscular de Valencia)\nSpin-isospin excitations can be studied by beta decay and charg e exchange reactions in mirror nuclei\, shedding light on mirror symmetry\ , hence we can compare our results on the beta decay of proton-rich nuclei with the results of charge exchange experiments when appropriate targets for the mirror nuclei are available [1].

HHG from solids has burgeoned a gr eat interest\, mainly motivated by the quadratic scaling of the harmonic c onversion efficiency with the density of the target\, as a result of the c oherent nature of the process.

El objetivo inicial era mejorar las pr estaciones en lo que se refiere a sensibilidad y precisión\, en espectrom etría de masas de alta precisión\, para aplicarla sobre elementos súper -pesados (Z>104)\, producidos en reacciones de fusión-evaporación\, con tasas de producción muy bajas\, y/o para aplicar el método sobre algunos isótopos específicos (187Re\, 187Os) para contribuir\, junto a otros ex perimentos de desintegración beta\, a medir la masa del (anti)neutrino el ectrónico [1]. La técnica propuesta podría sustituir otra bien establec ida (aunque no trivial)\, que amplifica la corriente inducida por medio de circuitos resonantes con la frecuencia de movimiento del ion [2]\, y que ha dado lugar a resultados de gran relevancia científica [3\,4]. No obsta nte\, dicho método no se ha demostrado con iones que tienen relaciones ma sa-carga elevada\, debido a limitaciones técnicas que reducen el cociente señal-ruido. \nLa técnica propuesta se basa en una idea original de D.J . Heinzen y D.J. Wineland [5]\, publicada en 1990 y no materializada hasta la fecha. Dos iones confinados cada uno de ellos en una trampa electromag nética\, interaccionarán a través de las corrientes que inducen si sus electrodos están comunicados por medio de un hilo conductor (o supercondu ctor). Para ello\, los iones deben oscilar con frecuencias en torno a 100- 300 kHz\, iguales en un nivel por debajo del hertzio\, cuando además dic ho control depende de fuentes de alimentación de voltaje continuas\, que pueden llegar a estabilidades de 10-7. Asumiendo que existe acoplamiento\, podríamos conocer la masa-carga de cualquier ion Xa+ (o Xa-)\, que movi éndose con una energía del orden de 10-3 eV\, generará una fuerza oscil ante sobre el otro ion (40Ca+) que previamente ha sido enfriado con láser es hasta la temperatura de ~1 mK. Una ventaja significativa que se espera obtener de utilizar esta técnica es que debido a que la amplitud de oscil ación del ion 40Ca+ enfriado es inferior a la temperatura de un ion enfri ado de forma resonante con un circuito a 4 K\, se logra una mejora evident e en sensibilidad si cualquier perturbación por pequeña que fuese es vis ible y con ello\, una mejora en exactitud hasta alcanzar el límite cuánt ico. Pero el efecto de “conexión” entre dos iones no se ha demostrado hasta la fecha\, cuando los iones están en trampas distintas. Para conse guir la conexión entre iones hay que reducir las dimensiones de las tramp as a utilizar\, respecto al tamaño de las utilizadas en física nuclear\, y emplear técnicas de micro-mecanizado. Además existe un aumento de ene rgía no despreciable (en torno a 0.2 μeV/s medido en una trampa específ ica en Granada) cuando los láseres no actúan (momento de interacción e ntre los iones)\, que se debe reducir\, y por lo que el sistema debe funci onar a 4 K. \nEl grupo de D.J. Wineland en NIST (Boulder) publicó en 201 1 la conexión entre iones en la misma trampa de radiofrecuencia pero sepa rados por un pozo de potencial [6] y el grupo de H. Häffner en Berkeley [ 7] está trabajando en ello\, también con trampas de radiofrecuencia\, p ara conseguir lo que sería un hito en el marco de la electrónica cuánti ca. En Granada\, el hecho de utilizar trampas Penning para su uso en espec trometría de masas con elemento súper-pesados [8]\, conllevará a un men or calentamiento del ion\, pero el campo magnético de 7 tesla origina un mayor número de transiciones en el proceso de enfriamiento. Para enfriar el ion de 40Ca+ en ausencia de campo magnético\, sólo son necesarios dos láseres: uno de longitud de onda de 397 nm\, para acceder a la transici ón dipolar eléctrica 4s2S1/2→4s2P1/2\, y otro con longitud de onda de 866 nm\, para bombear del estado 3d2D3/2\, al que decae en el proceso de e nfriamiento con una probabilidad del 7%\, y continuar en el ciclo de enfri amiento. El confinamiento en 7 Tesla\, origina un desdoblamiento de nivele s por efecto Zeeman en primer y segundo orden\, además de mezcla de estad os en la estructura fina\, que hacen necesarios 12 láseres para el proces o de enfriamiento. \nPara superar estos obstáculos y poder llegar al obje tivo final ha sido necesario montar tres experimentos con trampas y uno de criogenia. En esta contribución hablaré de cómo hemos ido construyendo este laboratorio de trampas de iones\, el único en España de esta natur aleza\, con una financiación total de 3 millones de euros. Mostraré las distintas trampas y sistemas de láseres\, cómo solventamos los aspectos técnicos más relevantes expuestos con anterioridad\, y los resultados ob tenidos [9-14] y sus implicaciones en física nuclear\, en relación a exp erimentos en el GSI de Darmstadt y a la futura instalación MATS en FAIR\, así como en el marco de las tecnologías cuánticas. Concluiré mostrand o las previsiones para alcanzar el objetivo final de conexión entre iones .\n\nAgradecimientos\n\nEste laboratorio ha sido financiado por el Consejo Europeo de Investigación (ERC StG 278648-TRAPSENSOR) junto con los proye ctos MINECO/FEDER FPA2012-32076\, FPA2015-67694-P\, UNGR10-1E-501 y UNGR13 -1E-1830\, y Junta de Andalucía/FEDER IE_57131.

Such structural o rganization can be observed at different scales\, ranging from aggregates of atoms in the gas-phase to colloids in condensed-matter physics. From th e theoretical view point\, one has to model the interactions among the par ticles of the system (e.g.\, atoms or molecules) and\, then\, apply optimi zation techniques. In general\, this is a very difficult task that require s the application of state-of-the-art optimization methods. Over the past decade or so\, we have developed evolutionary algorithms (EAs) that has be en able to discover putative global minima for various cluster systems\, i ncluding atomic [1-3]\, molecular [4] and colloidal [5\,6] clusters.\nIn t his talk\, we will present the main ingredients of our EA and its applicat ion to the solvation of ions [7\,8] as well as to the study of self-assemb ling phenomena in colloidal systems [6\,9\,10]. In particular\, we will fo cus on the study of alkali-ions solvation (Figure 1) and the formation of aggregates of charged colloidal particles (Figure 2). The analysis of the energetics and structure of the clusters relies on the features of the pot ential functions employed for modeling the interactions among the particle s.\n\nAcknowledgments\nWe acknowledge the support from the Coimbra Chemist ry Center (CQC)\, which is financed by the Portuguese “Fundação para a Ciência e a Tecnologia” (FCT) through the Project No 007630 UID/QUI/00 313/2013\, co-funded by COMPETE2020-UE.

It is estimated that 75-80% of all species became extinct\, including all marine dinosaurs and almost all terrestrial dinosaurs. In 1980\,\nLuis Alvarez et al. prop osed that the extinction was caused by the impact of a 10-km asteroid\; in 1981\, Glen Penfield and Antonio Camargo identified the impact crater in the vicinity of the town of Chicxulub\, in the Yucatán Peninsula. We pres ent the results of numerical simulations of the consequences of the impact \, assuming as an initial condition that the impact\nproduced global fires that injected as much as 70\,000 Tg of carbon soot into the atmosphere. T he results show that a small part of this soot is entrained into the circu lation of the stratosphere and mesosphere\, where it remains suspended for a prolonged period\, absorbing solar radiation and blocking\nsunlight at the surface. As a consequence\, the Earth’s surface experiences a “glo bal night” lasting 1-2 years\, followed by a period of reduced illuminat ion (5-50% of normal) for another 4-5 years. The suppression of sunlight a t the surface causes global cooling of about 15°C (10-12° in the oceans and 25-30°C on land). At the same time\, the soot in heats the stratosphe re\, which warms by as much as 100°C. Stratospheric heating affects the c hemical composition and photochemistry\, such that the ozone layer is redu ced globally by 80% of normal\, which allows high levels of UV radiation t o reach the surface. The combination of darkness\, cold\, and enhanced UV flux appears to be able to account for the widespread pattern of extinctio n of Cretaceous flora and fauna.\n\nhttps://indico.ific.uv.es/event/2851/c ontributions/4093/ LOCATION:Santiago de Compostela\, Facultade de Química Aula Magna URL:https://indico.ific.uv.es/event/2851/contributions/4093/ END:VEVENT BEGIN:VEVENT SUMMARY:Electromagnetic metamaterials for magnetic resonance imaging in me dicine DTSTART;VALUE=DATE-TIME:20170719T143000Z DTEND;VALUE=DATE-TIME:20170719T144500Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4090@indico.ific.uv.es DESCRIPTION:Speakers: Manuel Freire (Universidad de Sevilla)\nMetamaterial s are artificial composites whose electromagnetic properties can be engine ered to achieve any value of effective permittivity and/or permeability.

The ability of metamate rial lenses with negative permeability to increase the signal-to-noise rat io (SNR) in magnetic resonance imaging (MRI) has been investigated. Moreov er\, it has been also analyzed the ability of metamaterial slabs with zero /high permeability to reject/confine the RF magnetic field in MRI systems and thus to locally increase the SNR.

For instance\, in QFT\, the scattering matrix\, the mathematical object connecting input an d output free states\, must follow the so-called cluster-decomposition pri nciple\, which says that the scattering amplitude factorizes as a product of single-particle amplitudes for causally disconnected input states. In t his work\, we find that the cluster-decomposition principle also occurs in a non-causal system: the nonrelativistic scenario of waveguide QED\, wher e a one-dimensional photonic field interacts with some scatterers. We firs t show a Lieb-Robinson-like bond holds for the free theory\, so the system is approximately causal if there are not scatterers. We then show that th e ground state of the full model is equivalent to the vacuum far away from the scattering region\, so we can properly define free input and output s tates. We then show the Lieb-Robinson-like bond also holds for the full sy stem. Lastly\, considering that there are more stable states apart from th e ground state\, we show that the scattering amplitude for a bunch of caus ally disconnected incident photons is composed by a product of one-photon amplitudes\, with a sum over all the stable states\, so the cluster-decomp osition principle holds. We find the structure for the S-matrix in positio n space compatible with this scattering amplitude. We finally illustrate o ur results with two examples: (i) a two-level system ultrastrongly coupled to a dispersive medium and (ii) a general scatterer coupled to a waveguid e with linear dispersion relation. In the first example\, we show the clus ter properties hold. In the second one\, we find the structure for the S-m atrix in momentum space and compute how the photon-photon correlations gen erated by this S-matrix decay with the distance between the incident photo ns.\n\nhttps://indico.ific.uv.es/event/2851/contributions/4088/ LOCATION:Facultad Química (USC) Aula Química General URL:https://indico.ific.uv.es/event/2851/contributions/4088/ END:VEVENT BEGIN:VEVENT SUMMARY:Coherent control of nonlinear optical processes in single optical nano-antennas DTSTART;VALUE=DATE-TIME:20170718T140000Z DTEND;VALUE=DATE-TIME:20170718T143000Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4085@indico.ific.uv.es DESCRIPTION:Speakers: Nicolo Accanto (CNRS\, Paris Descartes Univerity)\nO ptical nano-antennas have the capability to control the localisation of li ght on nanometer spatial scales.

Excessive amounts of pollutants in the atmosphere is at the root of environmental issues being carbon dioxide (CO2) one of the main greenhouse gases present in the atmosphere [1]. The concentration of this gas in the air has increased by 30% since the 19th century mainly due to intensive use of fossil fuels like coal\, oil or nat ural gas (80% CO2 emissions worldwide) and human activity. Moreover\, the International Panel on Climate Change (IPCC) has predicted that CO2 levels in the atmosphere could reach up to 590 ppm by 2100 entailing the rising of almost 2 ºC in the globe [2]. These high values can be obtained in par t due to the economic and industrial growth of developing nations\, where energy sources with a strong carbon footprint are extensively used. For th is reason humans have two challenging issues to address: to find and use a sustainable source of energy and also to reduce greenhouse emissions to a chieve environmental protection [3]. \n\nAt present\, CO2 is collected fro m the atmosphere using absorption processes in which chemical reactions ma y or may not be involved. The most common procedures are based on the use of basic aqueous solutions of NaOH and KOH or amine scrubbing. The main dr awback is the energy that requires\, which translates into high economic a nd environmental cost. Other limiting factors of this technology are the c orrosive and environmentally unfriendly character of the reagents involved \, the engineering of large and complex absorption units and also the ther mal degradation of solvents such amines. The urgency for materials that ca n be used within CO2 capture has prompted the study of several technologie s such as: boron nitride nanotubes\, ionic liquids\, porous inorganic memb ranes (PIMs)\, polymers with light organic functional groups\, inorganic-o rganic interface composites\, covalent organic framewoks (COFs)\, metal or ganic frameworks (MOFs) and zeolitic imidazolate frameworks (ZIFs) among o thers tested recently [4].\n\nWe use of molecular simulations with the aim of obtaining new compounds that have improved properties over the existin g ones such as: high capture capacity\, high recyclability\, good thermal stability and easy desorption protocols of captured gases if necessary\, a s well as a high selectivity in the adsoption of certain pollutants. With the aid of computer-aided simulation it is possible to study prior to the synthesis static and dynamical properties such as: the affinity for differ ent gases\, capture capacity\, isotherms that govern the process\, dynamic s of the adsoption and time scale and also the ability to identify the deg ree of occupation of the structure among other properties [5-6]. Bulky sol utions of soluble compounds in a specific solvent or extended solids with periodic boundary conditions are often used. \n\nMany of the problems that would desirable to tackle with molecular modeling (interesting properties in carbon capture and storage materials) are\, unfortunately too large to be studied by means of quantum mechanics since they imply prohibitive com putational cost. To deal with this problem\, molecular mechanics (MM) is t hus invariably used to perform calculations on systems containing a large number of atoms and to simulate systems which the smallest spatial dimensi on is higher than nanometres [7]. In spite of this\, it is necessary to de lve deeper into the potentials that are being used in force fields and rep arametrize them\, if necessary\, to obtain a correct description of comple x systems such as MOFs\, ZIFs\, COFs among others.\n\nCommunication Main B ody\n\nWith the aim of testing the general performance of force fields\, D REIDING\, AMBER and UFF were selected and compared with high level ab-init io calculations. Among the force fields\, we were not able to use the AMBE R force field since it does not have parametrized the cumulene carbon of C O2\, thus\, both UFF and DREIDING have been used to perform calculations u sing a conventional parametrization and an extra one with charge equilibra tion on all atoms. The charge equilibration method (QEq) proposed by Rapp é et al. That uses as input data experimental atomic ionization potential s\, electron affinities\, and also atomic radii was used to assign charges to all atoms in both DREIDING and UFF. Some CO2-five-membered-ring hetero cycles complexes have been considered for the analysis of the intermolecul ar interaction potential. Electron-Donor-Acceptor (EDA) complexes between CO2-and heterocycles have been used to analyse the binding energy predicti on ability of force fields. \n\nOnce the inability of the force fields to correctly describe the interactions between CO2 and heterocycles (which ar e the fundamental links of the structures of the carbon dioxide capture co mpounds) has been demonstrated\, then the study and parametrization of the interaction potentials computed with high-level ab-initio methods is carr ied out. Two major groups of study will be considered: interaction with th e main structure of the heterocycle (carbon skeleton\, π-electron density \, interaction with the main heteroatom etc.) in different possible config urations and the study of hydrogen bond interactions between CO2 and X-H f ragments of the heterocyclic structures. All interaction curves have been parametrized according a Lennard-Jones potential. \n\nAcknowledgments\nThe authors thank the Centro de Supercomputación de Galicia (CESGA) for time on HPC infrastructures.

In t his way the Pu from spent fuel is used in a new reactor cycle\, contributi ng to the long-term sustainability of nuclear energy. The use of MOX fuels in thermal and fast reactors requires accurate capture and fission cross sections. For the particular case of 242Pu\, there are sizable discrepanci es among the cross section measurements available [2-5] all from the 70s\ , resulting in and uncertainty of 14% and 35 % below and above 2 keV\, res pectively. In this context\, the Nuclear Energy Agency (NEA) recommends in its High Priority Request List (HRPL) [6] and its report WPEC-26 [7] that the capture cross section of 242Pu should be measured with an accuracy of at least 8-10% in the neutron energy range between 500 eV and 500 keV. Th is work presents the time-of-flight capture measurement on 242Pu\, carried out at n_TOF-EAR1 (CERN) [8] featuring a white neutron beam with energies ranging from thermal to GeV. The 242Pu(n\,γ) reaction on a sample conta ining 95 mg of extremely pure 242Pu was measured with an array of 4 C6D6 T otal Energy Detectors [9]. This contribution focuses on the analysis and r esults in its resonance region. In this context\, the unique energy resolu tion feature by the n_TOF-EAR1 facility has enabled to resolve\, analyze a nd extract individual resonance parameters for more than 250 s- and p-wave resonances up to 4 keV\, 180 of which are not present in JEFF 3.2. Moreov er\, the achieved systematic uncertainty in the capture cross section is a round 4%\, fulfilling the requirements of the NEA-HPRL. Last\, the statist ical properties of the resonances have been studied in terms of their aver age resonance parameters and compared to the predictions of theoretical mo dels. A detailed version of this work can be found in Ref. [10].\nAcknowle dgments\nWe acknowledge the n_TOF Collaboration.

They offer unique properties as Plasma Facing Materials for a Fusion Reactor\; they are basically free from permanent damage by neutron and plasma irradiation and can be re-circulated and regenerated for lifet ime and particle and heat exhaust issues. The expected advantages for the power exhaust issues\, mainly arising at the divertor target at power dens ities of 10– 20 MWm−2\, relay on the self-healing properties of liquid surfaces as well as the ability to in situ replacement of the surfaces ex posed to the plasma by the effect of capillary forces (CPS design\, [2]). Among the possible liquid metals (LM) presently considered as candidates f or the development of an alternative solution to the Power Exhaust Handlin g in a future Fusion Reactor (Li\, Sn\, Ga)\, tin lithium alloys offer uni que properties in terms of evaporation\, fuel retention and plasma compati bility. This is the reason why this particular LM was chosen as main candi date in the US APEX project [3]. Very recently\, LiSn (20-30:80-70at.%) al loys have been exposed to ISTTOK and TJ-II and very promising results on D retention and surface segregation of Li were obtained [4\,5]. \nMotivated by these results a full campaign of comparative Li/ LiSn/Sn testing in TJ -II plasmas has been initiated. Liquid metal wetted CPS heatable electrode s have been manufactured in the Plasma Wall Interaction laboratory at CIEM AT and later exposed to TJII plasmas at different temperatures. For both s olid and liquid states a negligible perturbation of the plasma has been re corded in the Li and LiSn cases\, even when stellarator plasmas are partic ularly sensitive to high Z elements due to the tendency to central impurit y accumulation. The surface temperature of the liquid metal/CPS electrodes (made of a Tungsten mesh impregnated in SnLi\, Sn or Li) has been measure d during the plasma pulse with ms resolution by pyrometry and the thermal balance during heating and cooling has been used to obtain the thermal par ameters of the LM/CPS arrangements as well as to calculate the thickness o f the film interacting with the plasma. Temperatures as high as 1100K duri ng TJ-II plasma exposure were observed for the LiSn case and hints of sput tering-enhanced evaporation were deduced from the temperature dependence o f the lithium fluxes entering the plasma. \nFurthermore\, laboratory exper iments showing a much lower hydrogen retention of SnLi compared to Li (as expected) and a secondary emission coefficient (SEE) closer to pure Li hav e been undertaken in order to further study the relevant properties of tin lithium alloys for their possible use as PFC in a future reactor.\nIn thi s presentation a full account of the results obtained and their implicatio ns for the use of LM/CPS concepts in a future Fusion Reactor will be addre ssed. \n\nThis research was partially financed by the Spanish “Ministry of Economy and Competitivity” under project ENE2014-58918-R. \n\n[1] R.

Some experiments1\,2\,3 reported that during the exposure of MNPs to an AC field\, the temperature may increase several tens of kelvins at the parti cle surface and then rapidly decay to zero only a few nanometers away. The refore\, addressing the local (at individual particle level) heat dissipat ion becomes very relevant4. \nIn MFH\, global (whole system) heat dissipat ion is usually obtained from the area of the magnetization vs. applied fie ld M(H) hysteresis loops. However\, using the same approach for local hyst eresis cycles is not adequate for strong-interacting systems because coupl ed particles may have inverted hysteresis loops and therefore negative hys teresis areas. \nThe aim of this work is to find an alternative way to eva luate local released energy. To do so\, we work with the kinetic Monte Car lo technique\, which is suitable to describe heating processes of interact ing particle systems5. Our premise is that the hysteresis area of the enti re system stands for the total dissipated energy. We developed an approach where we analyze the different types of jumps of the energies of individu al particles and from there we are able recover the area of the entire sys tem.\n\nThis work was cofinanced by the Spanish MINECO (Project MAT2013-47 078-C2-2-P)\, Xunta de Galicia\, Spain (Project GRC 2014/013\, ‘Programa de axudas á etapa predoutoral’ and financial support of D.S. under Pla n I2C) and ‘Fondo Social Europeo 2014/2020’.\n\nhttps://indico.ific.uv .es/event/2851/contributions/4078/ LOCATION:Facultad Química (USC) Aula Química Analítica URL:https://indico.ific.uv.es/event/2851/contributions/4078/ END:VEVENT BEGIN:VEVENT SUMMARY:Structure and dynamics of ions in gas phase: interplay between exp eriments and theory in IRMPD spectroscopy DTSTART;VALUE=DATE-TIME:20170718T134500Z DTEND;VALUE=DATE-TIME:20170718T140500Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4076@indico.ific.uv.es DESCRIPTION:Speakers: Cecilia Coletti (Dipartimento di Farmacia\, Universi tà G. d'Annunzio Chieti-Pescara)\nIR vibrational spectroscopy is a widesp read technique for the characterization of molecules in gas phase\, highly sensitive to small structural changes\, like hydrogen bonding patterns\, thus allowing the detection of motifs and signatures o¬¬ccurring in rele vant processes. In the case of gaseous ions\, the low density of the sampl ed species requires the use of a sensitive 'action' spectroscopy approach such as IRMPD (IR Multiple Photon Dissociation) spectroscopy. By this tech nique the fragmentation due to absorption of multiple IR photons in resona nce with active vibrational modes of the molecular ion is probed by mass s pectrometry. The IRMPD spectrum is then obtained by reporting photo-fragme ntation yield as a function of the IR photon energy.\nThe interpretation o f the experimental spectra needs in any case a strong computational suppor t to correctly assign the main features to the corresponding vibrational m odes and to identify the populated isomers and/or conformers\, particularl y when flexible molecule are investigated. This combined approach has rece ntly allowed a comprehensive description at the molecular level for the re active events responsible for cisplatin activity\, including the first dir ect evidence of a prototypical Eigen-Wilkins encounter complex in solution .\nThe last years have also witnessed increasing applications of IRMPD kin etics experiments\, where the use of selected active IR photons can produc e selective photo-fragmentation of different isomers or even different con formers\, thus enabling the qualitative and quantitative characterization of their population in the experimental mixture.\n\nhttps://indico.ific.uv .es/event/2851/contributions/4076/ LOCATION:Facultad de Química (USC) Aula Matemáticas URL:https://indico.ific.uv.es/event/2851/contributions/4076/ END:VEVENT BEGIN:VEVENT SUMMARY:Search for new physics via baryon EDM at LHC DTSTART;VALUE=DATE-TIME:20170717T144500Z DTEND;VALUE=DATE-TIME:20170717T151500Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4075@indico.ific.uv.es DESCRIPTION:Speakers: Joan Ruiz Vidal (IFIC\, University of Valencia - CSI C)\nPermanent electric dipole moments (EDMs) of fundamental particles prov ide powerful probes for physics beyond the Standard Model.

The EDM of strange Λ baryons\, selected from weak decays of ch arm baryons produced in pp collisions at LHC\, can be determined by studyi ng the spin precession in the magnetic field of the detector tracking syst em. A test of CPT symmetry can be performed by measuring the magnetic dipo le moment of Λ and anti-Λ baryons. For short-lived Λ+c and Ξc+ baryons \, to be produced in a fixed-target experiment using the 7 TeV LHC beam an d channeled in a bent crystal\, the spin precession is induced by the inte nse electromagnetic field between crystal atomic planes.

Ver las dificultades con las que te topas en el paso de bachillerato a la universidad\, y la necesidad de\, entre otras materias\, haber dado algo d e álgebra en bachillerato. También queremos hablar de cómo conforme vas avanzando cursos\, la carrera gana belleza\, donde vas pasando de dar por encima toda la física\, a profundizar en electromagnetismo\, óptica\, c uántica\, etc. Otro de los objetivos es reflejar cómo el número de hora s de trabajo en algunas asignaturas\, no se ve reflejado en el número de ECTS que recibes por cursarlas. Finalmente\, hablamos de lo poco valorada que está la docencia en la universidad frente a la investigación\, desde nuestro punto de vista como estudiantes.\nNuestra experiencia personal\n ¿Cómo de bien preparados terminamos un bachillerato de ciencias? A lo la rgo del bachillerato\, y hablando únicamente de física y matemáticas\, salimos sabiendo integrar\, derivar y resolver matrices\, en cuanto a las matemáticas\, y sabiendo acerca de tiros parabólicos\, cinemática y\, e n menor cantidad\, óptica\, electromagnetismo y gravitación\, en cuanto a física. Empezamos la universidad y nos topamos con que nunca hemos pis ado un laboratorio de física\, o con que hay conceptos en los que hemos p rofundizado demasiado y en otros\, en cambio\, muy poco. No consideramos q ue salgamos mal preparados\, pero\, ¿salimos todo lo bien preparados que podríamos salir?\n\nAl margen de lo explicado\, nos centraremos concretam ente\, como un ejemplo particular\, en que si quieres estudiar física\, h ace falta ver más álgebra en bachillerato. Acabas el instituto sabiendo integrar de cien formas diferentes\, pero sin tener ni idea de álgebra m ás que una base de números complejos. Llegas al primer curso del grado y empiezas a darla\, en un año te dan muchos conceptos\, que te fascinan y a la vez te aterrorizan\, porque es totalmente nuevo y te cuesta trabajo entenderlo\, aunque acaba siendo una de las asignaturas que más gusta (ta mbién de más suspensos)\, qué pena no haber visto las matemáticas de e sta manera antes. Después te dejan tablas y tablas de integrales a lo lar go de la carrera y\, en cambio\, te topas con cuántica sin recordar bien lo que era un operador\, o lo que es un tensor\, dado que solamente lo has trabajado durante un curso\, y con muy poca aplicación en la física.\n\ nConforme vamos avanzando cursos\, y vamos dejando atrás ese primer año de adaptación\, de más matemáticas que física\, de más física clási ca que “moderna” y de asignaturas comunes a todas las ciencias\, que n o son especialmente vitales para nuestro futuro laboral\, por lo menos no los conceptos que nos enseñan\, comenzamos a ver esa física que tantas ganas teníamos de aprender: empezamos a ver cómo evolucionan las estrell as\, los misterios de la física cuántica\, la parte electromagnética de la óptica (y no sólo espejos y lentes)\, o la verdadera complejidad del átomo y de su núcleo formado por protones y neutrones.\n\n\nAun así\, nadie dijo que el camino fuera fácil\, pero\, una cosa es que no sea fác il\, y otra es que no sea lo que supuestamente ha de ser. Con esto pretend emos decir que el esfuerzo en una asignatura\, con un número de créditos determinado (en la cual cada crédito corresponde a un número de horas d e trabajo) no siempre se corresponde con lo que supuestamente debería ser . Esto\, entre otras cosas\, es debido al paso de licenciatura a grado\, a lgunas asignaturas que están consideradas de 5 créditos\, como en genera l los laboratorios\, ocupan mucho más tiempo que otras consideradas de m ás créditos\, ya que suelen ser sesiones de una mañana entera (4-5 hora s) y luego todavía te queda bastante trabajo para casa\, hay que analizar resultados\, hacer memorias\, y llevar una buena libreta\, todo esto conl leva tiempo\, mucho más del que se piensa.\n\nFinalmente nos gustaría ha blar del poco valor que\, según nuestra apreciación como estudiantes\, s e da a la docencia frente a la investigación\, parece que para algunos pr ofesores dar clase sea simplemente el precio que tienen que pagar si quier en investigar\, y quien pierde en estos casos son los alumnos. Si las encu estas de evaluación verdaderamente se tuvieran en cuenta\, probablemente a los estudiantes se nos formaría mejor. No motiva mucho estudiar una asi gnatura\, y mucho menos asistir a clase\, cuando tu profesor se dedica a s entarse y a leer diapositivas\, que son un buen recurso\, pero hay que sab er emplearlo\, o cuando se dedica a copiar en la pizarra apuntes sin siqui era pararse a explicarlos. En cambio\, también está la cara opuesta\, cu ando el profesor consigue que una hora de clase se te pase en cinco minuto s\, cuando ofrece un horario de tutorías amplio y abierto a cambios\, el que nos sube todo tipo de material al aula virtual\, en resumen\, el que s e preocupa por enseñar\, al que le importan los alumnos y su formación. Es precisamente en esas asignaturas donde el esfuerzo del profesor se ve r eflejado en la nota de los alumnos y donde los alumnos realmente aprenden y se enamoran aún más de la física.\n\nPara una mayor visión sobre con cretamente este último punto párrafo:\n\nhttp://www.uv.es/~azcarrag/pdf/ 2015%20CIAN%20Bolonia%203+2%20vs.%204+1.pdf\n\n\n\nReferencias\n\n[1] www. uv.es\\fisica\n[2] J.

The purpose of our study is to validat e a GATE model of the commercial PET/CT Siemens Biograph placed at the Uni versity Hospital of Salamanca (Spain). The geometry of the system was impl emented including the detector ring\, crystal blocks\, PMTs\,etc. The GATE simulation results were reconstructed with analytical and iterative algo rithms using STIR (Software for Tomographic Image Recostruction)\, an open source software for 3D PET and SPECT image reconstruction. Simulated data were compared to experimental results obtanied using the NEMA NU-2-2007 s tandard protocols. It consisted of sensitivity estimation\, count rate\, N EC curve\, scatter fraction\, spatial resolution and image quality (hot an d cold contrasts\, atenuation in the lung and percent background variabili ty).\nThe reults for 2D and 3D sensitivity\, scatter fraction\, count rate and parameters referring to the image quality were found to agree with ex perimental values. The simulated sensitivity obtained is 10.9 cps/kBq in t he center of the transaxial field of view and 8.85 cps/kBq at 10cm. Excell ent agreement between simulation and experiment can be seen in the spatial resolution results\, FWHM being 5.288 mm at 1 cm with GATE and 5.280 mm a t 1 cm experimentally. Simulated Scatter dispersion was 35.1% for a concen tration of 2.48 kBq/mL\, a value was lower than that provided by the manuf acturer.\nIn conclusion\, our study showed that our Monte Carlo model can be used to optimize\,simplify and reduce the simulation time for the quali ty control procedure of PET scanners.\n\nhttps://indico.ific.uv.es/event/2 851/contributions/4072/ LOCATION:Facultad de Química (USC) Aula Química Orgánica URL:https://indico.ific.uv.es/event/2851/contributions/4072/ END:VEVENT BEGIN:VEVENT SUMMARY:Instalaciones científicas singulares en España con investigació n en Física DTSTART;VALUE=DATE-TIME:20170718T163000Z DTEND;VALUE=DATE-TIME:20170718T165500Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4071@indico.ific.uv.es DESCRIPTION:Speakers: Soler Ferran Pablo (RSEF)\nEl objetivo de esta comun icación es presentar las principales instalaciones tecnocientíficas en\n territorio español relacionadas con la física\, incluyendo\, desde un pu nto de vista general\, las\ndiferentes líneas de investigación asociadas .

Este material tiene grandes ventajas\, como son: su bu ena conductividad iónica a bajas temperaturas (menores a 100 °C) y sus b uenas propiedades mecánicas para el uso en pila de combustible [3]. No ob stante\, también presenta importantes inconvenientes como son: su elevado precio\, la necesidad de altos niveles de humedad para poder trabajar int ercambiando protones y la imposibilidad\, por lo tanto\, de hacerlo cuando las temperaturas son mayores de 100ºC [4]. El trabajo por debajo de hech o de 100 °C tiene varias desventajas\; la necesidad de uso de catalizador es nobles capaces de llevar a cabo las reacciones de oxidación de hidróg eno y reducción de oxígeno con cinéticas adecuadas\, la necesidad de al imentar el dispositivo con hidrógeno puro como combustible sin impurezas de CO\, S\, etc. con la consiguiente pérdida de eficiencia del dispositi vo.\nEn este trabajo se presentan membranas compuestas basadas en Nafion® y modificadas con la incorporación en su estructura de hidróxido doble laminar (LDH) Mg2Al hibridado y además con sepiolita. El objetivo a alcan zar con estos materiales\, esta relacionado con poder aumentar la temperat ura de operación de las pilas de combustible por encima de los 100 °C ma nteniendo una elevada conductividad iónica en las membranas. La hibridaci ón del LDH con la sepiolita será la encargada de aumentar la retención de agua en las membranas\, permitiendo de este modo que esta se libere por encima de los 100 °C\, manteniendo e incluso mejorando la conductividad de la membrana a estas temperaturas.\nLa síntesis de las membranas se lle va a cabo mediante el proceso de casting que consiste en la dispersión y mezcla de los materiales en una disolución de dimetilacetamida (DMAc) y e l calentamiento de ésta obteniendo finalmente una membrana homogénea par a su posterior estudio. Se han obtenido diferentes membranas con diversos porcentajes de LDH and sepiolita con la finalidad de e analizar el efecto de los aditivo e intentar diseñar la composición óptima para la aplica ción descrita anteriormente. \nLa caracterización físico-química de la s membranas sintetizadas se lleva a cabo mediante diferentes técnicas: mi croscoscopía electrónica de barrido (SEM)\, espectroscopía infrarroja ( FTIR) con el fin de conocer la composición y morfología de las mismas. A demás\, se han realizado ensayos de termogravimetría (TGA) para tratar d e conocer las prestaciones de las hibridaciones a temperaturas superiores a 100 °C así como la temperatura de operación óptima de los distintos materiales. \nTeniendo en cuenta su aplicación futura\, se realizan medid as de las propiedades mecánicas de las membranas obteniendo el módulo de Young\, de modo que se puede conocer la manejabilidad de estos materiales como electrolitos sólidos para pilas de combustible de membrana polimér ica. Por último\, se realizan medidas de absorción de humedad de las mem branas a diferentes temperaturas\, obteniendo datos relevantes sobre la ca pacidad de captación de agua. \nSe llevan a cabo medidas de conductividad iónica de las membranas modificadas con el fin de conocer la aplicabilid ad como intercambiadores iónicos a diferentes temperaturas. Mediante m edidas de impedancia de los electrolitos\, puede analizarse la variación de la conductividad con la temperatura para cada una de las membranas en l as distintas composiciones y compararlas con el Nafion® sin modificar. De este modo\, se puede realizar una primera aproximación del funcionamient o que presentarán estos materiales en la aplicación final.\nPor último\ , se realizan medidas en pila de combustible con H2/ O2 como reactivos con la finalidad de conocer el rendimiento de los dispositivos con las difere ntes membranas sintetizadas y se comparan con membranas de Nafion®.

Only the weak inte raction (of the four fundamental ones) is known to mediate processes where the Charge-Parity (CP) symmetry is violated (this meaning different produ ction rates for particles and antiparticles). However\, the size of this e ffect is very small\, and new sources of CP violation (outside the Standar d Model) are searched for.\n\nThe LHCb experiment\, at CERN\, is designed to study CP violation in the decays of hadrons containing b (beauty) quark s\, produced in proton-proton collisions in the Large Hadron Collider. New heavy particles may enter such processes via “quantum loops”\, modify ing the properties of the transition and impacting the CP-violating observ ables. An accurate measurement of such observables can thus hint the prese nce of New Physics.\n\nThe decay Bs0 → K∗0(→ K+π−)K ̄∗0(→ K −π+) is a golden channel for LHCb. The observable to be measured in thi s case is the weak phase φs\, arising in the interference between the amp litudes of Bs0 mesons decaying directly into K∗0K ̄∗0 and those decay ing after Bs0 − B ̄s0 oscillation. It is possible to generalise this fr amework to include other (non K∗0) Kπ components in the decay chain\, i ncreasing the available statistics and thus the accuracy of the measuremen t. In this talk\, the first analysis aimed at measuring φs in Bs0 → (K+ π−)(K−π+) decays\, with the Kπ pairs arranged in different spin con figurations (0\, 1 and 2)\, is presented.\n\nhttps://indico.ific.uv.es/eve nt/2851/contributions/4067/ LOCATION:Facultad de Química (USC) Aula Química Técnica URL:https://indico.ific.uv.es/event/2851/contributions/4067/ END:VEVENT BEGIN:VEVENT SUMMARY:Fluid model for the streamer-to-leader transition in lightning ch annels.

Pese a su simpleza\, este índice resultó de gran utilidad en los estud ios solares y en la física terrestre-solar. Así\, el vulgarmente conocid o como “número de manchas solares” (sunspot number) se convirtió con el tiempo es una de las series temporales más famosas de la estadística \, la astrofísica y la geofísica [3].\nSin embargo\, dos investigadores americanos realizaron en la década de 1990 un enorme esfuerzo para obtene r una versión independiente del “número de manchas solares” que deno minaron “Group Sunspot Number”. Recuperaron una gran cantidad de antig uas observaciones e idearon una metodología más sencilla y robusta que l a propuesta por Wolf hace un siglo y medio. Los resultados [4] fueron sorp rendentes ya que las diferencias en la parte histórica de la serie eran v erdaderamente notables. Además\, destacaba una importante y robusta tende ncia creciente en la actividad solar desde la finalización del Mínimo de Maunder (1645-1715) hasta nuestros días.\nLas diferencias era tan notabl es entre las dos versiones de la actividad solar de los últimos siglos a partir de observaciones de manchas solares que varios científicos de la c omunidad de la física solar y heliosférica propusieron la celebración d e varios talleres sobre el “sunspot number” y una revisión completa\, resultado de estas reuniones\, fue publicada a finales de 2014 [5].\nEste último trabajo ha provocado una importante reacción de la comunidad int ernacional hasta el punto de que un número monográfico de más de 600 p áginas de la revista “Solar Physics” ha sido publicado recientemente con trabajos exclusivamente dedicados al “sunspot number” [6]. Entre l os logros conseguidos\, merece la pena destacar la creación de una nueva colección de observaciones del número de grupos de manchas solares desde 1610 hasta la actualidad con más de un millón de registros [7].\nEsta n ueva versión del “sunspot number” presenta algunas características q ue provocan una serie de importantes consecuencias para las ciencias de la atmósfera. Se ha demostrado que la tendencia positiva en la actividad so lar que presentaba el “Group Sunspot Number” era un problema de homoge neidad de uno de los observadores primarios de la reconstrucción. Esto mo difica notablemente nuestra idea sobre la evolución en los últimos siglo s de la irradiancia total solar\, un parámetro fundamental para los model os climáticos. Además\, la elección de una nueva escala ha provocado qu e los números absolutos de la nueva versión sean mayores. Esto puede pro vocar problemas para los usuarios habituales del “sunspot number” como los científicos que estudian la ionosfera.\nEste trabajo ha sido parcial mente financiado por la Junta de Extremadura (GR15137) y por el Ministerio de Economía y Competitividad del Gobierno Español (AYA2014-57556-P).\nR eferencias\n[1] R.

Their contribution to the final decay rate is\, the refore\, of a similar order of magnitude of the otherwise sub-leading peng uin process. This situation enhances the interference effects between the two processes and allows the measurement of their relative weak phase diff erence. The relative importance of the penguin diagrams in charmless proce sses could allow the detection of new particles entering in the loops whic h would cause deviations from the branching fractions and CP asymmetries p redicted by the SM. \n\nThe LHCb detector consists of a single-arm forward spectrometer specifically designed for flavour physics. The characteristi cs of this design include a very good vertex and tracking resolution\, a f ully instrumented forward coverage that maximizes the acceptance of the bb quark pairs produced at the LHC and a very efficient particle identificat ion (PID) system separating protons\, pions and kaons in the full acceptan ce. Together with a high performing trigger\, these vertexing and PID effi ciencies are crucial in order to study flavour physics in the very complic ated hadronic environment of the LHC. \n\nIn this talk the latest results on charmless b decays by the LHCb collaboration will be presented\, with p articular emphasis on the amplitude analysis of the B0->(pi pi)(K pi) deca y.

Renewable energies (RE) such as solar and wind have an strong dependence on the meteorologica l conditions. This leads to a large temporal variance. Therefore there sh ould be some other complementary systems to fit the energy production (EP) to the demand (ED). \n\nIt is a challenge try to minimize the costs assoc iated to the growth of renewable power systems. In this work we propose di fferent possibilities to face this problem. \nThe first approach consists of distributing solar and wind farms in a smart way\, trying not only to get maximum capacity factor\, but to minimize the temporal variance of the production respect to the energy demand. This problem has been already pr esented for the Iberian Peninsula at monthly time scales [1]. In this work we applied the same methodology at daily time scale.\nThe method is appli ed to a database of solar and wind power potential generation constructed from the outputs of regional climate models runs (hindcast data) with a sp atial resolution of 10km over the Iberian Peninsula. The quality of this d ata has been extensively proved [2] \nIn spite of the strong reduction of the variance by applying this methodology\, there still exists importat differences respect the energy demand . When RE is larger that ED the ene rgy should be stored. In this work we only deal with pumped-storage hydroe lectricity. The most storage we need the higher the associated costs will be. On the other hand if storage is insufficient some energy will be lost. When RE is smaller other systems should be switch on. If there is energy stored previously this should be used. If not\, we need some extra energy power systems. Therefore it is necessary to reach a compromise between our RE installed power\, pumped-storage capacity and extra systems in ord er to minimize the costs assciated. \nIn this work we present an study of the configuration that the whole power system (electricity) should have in order to minimize costs and maximize the use of RE. This estimation has been obtained for the current (mean of last 5 years) ED in Spain and Port ugal.\n\nhttps://indico.ific.uv.es/event/2851/contributions/4063/ LOCATION:Facultad Química (USC) Aula de Física URL:https://indico.ific.uv.es/event/2851/contributions/4063/ END:VEVENT BEGIN:VEVENT SUMMARY:Challenging the Standard Model with top quarks interactions DTSTART;VALUE=DATE-TIME:20170717T151500Z DTEND;VALUE=DATE-TIME:20170717T154500Z DTSTAMP;VALUE=DATE-TIME:20260419T051051Z UID:indico-contribution-2851-4059@indico.ific.uv.es DESCRIPTION:Speakers: Maria Moreno Llacer (CERN)\nThe elementary particles \, their properties and their interactions are described by the Standard M odel (SM)\, which is the theoretical framework for the study of the strong interactions of quarks and gluons and the unified electroweak force by me ans of a modelling framework based on local gauge invariance. The SM is ve ry successful in accounting for most of the observed phenomena at the micr oscopic frontier of physics\, verified and tested in many experiments in t he last decades\, also including the discovery of the Higgs boson by the A TLAS and CMS experiments at the LHC facility at CERN laboratory in 2012. H owever\, new theories beyond the SM are still needed to explain many pendi ng questions in physics: the matter-antimatter asymmetry\, the pattern of flavour mixings and fermion masses\, the nature of dark matter or the acce lerated expansion of the Universe.\nThe SM accommodates the measured masse s\, but it does not explain the vastly different mass scales spanned by th e known particles. The dynamics of flavour and the origin of CP violation are also related to the mass generation\, but still not fully understood. The SM should be either extended or replaced by a more general modelling f ramework\, but experimental evidences are needed to point in which directi on the SM should be modified.\nThe top quark is a very sensitive probe of the electroweak symmetry breaking\, since it is the heaviest fundamental p article with the SM framework.Its large mass makes the top very different from all other quarks\, with a Yukawa coupling to the Higgs boson close to unity. For these reasons the top quark and the Higgs boson play very spec ial roles in the SM and in many extensions thereof. An accurate knowledge of their properties (mass\, couplings\, production cross section\, decay b ranching ratios) can bring key information on fundamental interactions at the electroweak breaking scale and beyond. Some of the top quark couplings were investigated at the Tevatron\, while others\, such as the coupling o f the top quark to the Z or the Higgs boson are becoming accessible only w ith the high-statistics top quark sample at the LHC.

The ads orption of alcohol molecules in the walls as well as their distribution in the directions normal and parallel to the interface are studied. The resu lts of these simulations are compared with results of the pure IL and its mixtures with water\, which were previously reported in ref. [1]. \nAll th e results suggest that alcohols distribute quite uniformly throughout the box\, being almost totally depleted from graphene walls. The distribution of ions of the first and second layers closest to the electrodes in the di rection parallel to these are also studied by means of bidimensional densi ty maps\, showing a clear structural transition from a striped pattern to an hexagonal one with the concentration of cosolvent and also when the siz e of the cosolvent molecules increases. These transitions seem to be highl y sensitive to the presence of cosolvent molecules in the ionic layers clo sest to the electrodes. It was also corroborated that the bidimensional io nic structures persist in the second ionic layer close to the graphene wal ls.\nThis persistence of the bidimensional ionic structure combined with t he electric double layer (see refs. [2-5]) strongly conditions the three d imensional ionic structure near charged interfaces in these dense ionic sy stems. Moreover\, recent studies have shown that this bidimensional struct ures appear in ILs in other circumstances\, like mixtures with salts\, mix tures with other cosolvents solvents like water or when the graphene walls have vacancy defects (see ref. [6]). In this work we report the formation of these structures when the molecular size of the solvent changes.\n\nRe ferences\n\n[1] B. Docampo-Álvarez\, V. Gómez-González\, H. Montes-Camp os\, J. M.
