Dear colleagues,
We apologise in advance if you receive this announcement multiple times.
We would like to draw your attention about the Second edition of our School on Lattice Techniques for Cosmology, that we will organise ONLINE during September 25-29 2023. The school is aimed to provide a pedagogical introduction to lattice field theory techniques and their use to simulate the classical dynamics of interacting fields in an expanding background. The lectures will serve 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, and possibly others, 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.
Registration will be open till Sept. 5th 2023, see
Observations: The school will be held ONLINE, during 25-29 Sept 2023. Applications can be accepted till Sept. 5th 2023. There is no fee to participate in the school. A preliminary schedule considering overlapping day-time windows within Europe, India and China has been set up. In order to do practice sessions, participants will need to have access to a personal computer or to a cluster.
The program 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
