CosmoLattice School '23 (Online), Sept 25-29

25 Sep 2023, 09:00 → 29 Sep 2023, 16:00 Europe/Madrid

Daniel G. Figueroa (IFIC)

This is the second edition of our school on lattice techniques for cosmology,  which will be online in this occasion. Our school is aimed to provide a pedagogical introduction to lattice field theory techniques and their use to simulate the dynamics of interacting fields in an expanding background. The lectures will serve as well as an introduction to CosmoLattice, a public code developed for lattice simulations of early Universe scenarios. The use of CosmoLattice as a tool to simulate scalar and gauge field non-linear dynamics in an expanding universe will be presented in full detail. Modern applications to inflation, preheating, gravitational wave production, non-minimally coupled scalar field dynamics, axion-like field dynamics, etc, will also be covered.

The school is aimed to anyone who would like to learn (or simply improve their knowledge on) how to simulate in a lattice the dynamics of early Universe field theory scenarios. The lectures will cover:

* Lattice field theory techniques: discretisation schemes, lattice gauge techniques, and more.
* Numerical algorithms for differential equations: Leapfrog, Verlet, Runge-Kutta, etc
* Overview of CosmoLattice: libraries, modularity, parallelisation, ...
* Lattice simulations of interacting fields in an expanding background:
    - Scalar field dynamics with arbitrary potentials
    - U(1) gauge theories with complex charged scalars
    - SU(2) gauge theories with doublet charged scalars
* Modern applications to early Universe scenarios:
    - Preheating scenarios and onset of radiation domination
    - Production and evolution of gravitational waves
    - Dynamics of derivatively coupled Axion-like fields
    - Dynamics of non-minimally coupled scalar fields
    - Others, if time permits

Observations: The school will be online, during 25-29 Sept 2023. Applications can be sent till Sept. 8th 2023 through this website. There is no fee to participate in the school. In order to do practice sessions, participants will need to have access to a personal computer (laptop or desktop) or a cluster. A preliminar schedule considering overlapping day-time windows within Europe, India and China has been set up, with everyday lectures running from 9:00 - 16:00 CET (Central Europe) / 12:30 - 19:30 (India) / 15:00-22:00 (China).

 

We look forward to seeing you online!
