Periodically driven systems have been successfully used to implement topological band structures with non-zero Chern numbers for non-interacting neutral particles. The extent to which the engineered topological properties survive in the presence of interactions, and which many-body phases result, remains however a largely open question. In order to experimentally control the interactions, and to study the resulting many-body physics, we prepare a BEC of 39K which has an accessible Feshbach resonance. By tuning the interactions as well as the driving strengths and frequencies, we can systematically explore the non-equilibrium dynamics in a shaken 1D lattice as well as in a shaken honeycomb lattice.
