Dear colleagues,
We apologise in advance if you are receiving this announcement multiple times.
We would like to draw your attention about the third edition of our school on lattice techniques for cosmology, the CosmoLattice School 2025. This event will take place from September 22nd to 26th, 2025, at the Institute for Basic Science (IBS), in Daejeon, South Korea.
Registration will open on June 20th 2025 and will remain open until August 31st 2025, for further details see
https://indico.ific.uv.es/event/8110/
This school is aimed to anyone who would like to learn about (or improve their knowledge on) the theory framework for lattice simulations of non-linear dynamics of early Universe scenarios. We will provide a pedagogical introduction to lattice field theory techniques and their application to the simulation of interacting fields in an expanding Universe. Participants will be introduced to CosmoLattice (https://cosmolattice.net/), an open-access code designed for such simulations. The school will provide a comprehensive guide to using CosmoLattice for studying the non-linear dynamics in an expanding universe of scalar and gauge fields, as well as of relativistic fluids (representing particle ensembles).
The tentative program of the school will cover:
Theory lectures:
Lattice field theory techniques: discretization schemes, lattice gauge techniques, and more
Numerical algorithms for differential equations: Leapfrog, Verlet, Runge-Kutta, etc
Lattice simulations of interacting fields in an expanding background:
Scalar field dynamics with arbitrary potentials
U(1) gauge theories coupled to complex charged scalars
SU(2) gauge theories coupled to doublet charged scalars
Relativistic and non-relativistic fluid dynamics
Overview of CosmoLattice: libraries, modularity, parallelization, ...
Pheno lectures:
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
Fluid dynamics and its gravitational wave production
Evolution and experimental signatures of topological defects
Observations: There is no fee to participate in the school. In order to do practice sessions, participants will need to have access to a personal laptop.
Organizers: Mohammad Ali Gorji, Daniel G. Figueroa, Masahide Yamaguchi
We look forward to seeing you in Daejeon!
