DESCRIPTION:Speakers: Jan Schütte-Engel (University of Illinois Urbana-Ch
 ampaign)\nIt has been suggested that certain antiferromagnetic topological
  insulators contain axion quasiparticles (AQs)\, and that such materials c
 ould be used to detect axion dark matter (DM). In the first part of this t
 alk we show that one can detect AQs with transmission spectroscopy. The tr
 ansmission coefficients including material losses are computed by applying
  appropriate boundary conditions. We show that by comparing our signal cal
 culation to future THz transmission experiments the existence of AQs can b
 e proven. Furthermore\, the comparison can be used to fully characterize t
 he material parameters.\nIn the second part of this talk we show that AQs 
 can be used for axion DM detection. The dispersion relation and boundary c
 onditions permit resonant conversion of axion DM into THz photons. The res
 onance frequency is tunable with an external B-field. A parameter study fo
 r axion DM detection is performed\, computing boost amplitudes and bandwid
 ths using realistic material properties including loss. The proposal could
  allow for detection of axion DM in the mass range between 1 and 10 meV us
 ing current and near future technology.\n\nhttps://indico.ific.uv.es/event
