CosmoLattice

After an initial exponentially fast period of expansion ("inflation"), the content of the universe as we know it today is created by
transferring the energy responsible for inflation into standard model particles. This phase of "preheating" is dominated by non-linear
classical physics and has to be resolved numerically. After reviewing this problem, I will present CosmoLattice, a user-friendly, modern,
parallelized and versatile C++ framework to perform such simulations, with scalar, Abelian and non-Abelian fields. I will also explain how
this framework is particularly adequate to develop any kind of new software operating with "fields" on lattices, be them related to
cosmology or not.
