Many Body Localization (MBL) offers a generic alternative to thermalization in isolated quantum systems in which a many-body system fails to act as its own heat bath, even at finite energy densities. However, it is crucial for such a phenomenon that the system undergoes strictly closed system dynamics.
We present our recent work on probing MBL with ultra-cold fermions loaded in optical lattices by preparing an out of equilibrium change density wave and monitoring the relaxation dynamics. We will describe two experiments where we studied the effects of taking the system controllably away from the ideal isolated 1D case and describe how it influences the many-body state.
