1st School: 2022 (Valencia)

The 1st \(\mathcal{C}\mathtt{osmo}\mathcal{L}\mathtt{attice}\) school was held in IFIC, Valencia, Spain, with over 45 participants, during Sept. 5-8 2022. The school aimed to provide a first pedagogical introduction to lattice field theory techniques and their adaptation to simulate the dynamics of interacting fields in an expanding background. The lectures served as well as an introduction to \(\mathcal{C}\mathtt{osmo}\mathcal{L}\mathtt{attice}~{\tt v1.0}\), which back then had just been publicly released the year before.
