In this grant application we propose to continue our research on cold gases in an optical lattice. We would like to understand them quantitatively better in a variety of contexts:- Hubbard type of models- polaron models and disordered modelsThis will be done with a combination of analytical and numerical (Monte Carlo) methods.We would also like to know what those models can tell us about real materials, by exploring 2 new algorithmic advances:- Diagrammatic Monte Carlo will be used for the study of higher order corrections to the GW method- we will apply Monte Carlo methods in the context of tensor network states, which could offer new opportunities to study frustrated magnetism.
