Over the last ten years, experimental advances with ultracold quantum gases in optical lattices have made possible the study of various interesting many-body phenomena that are difficult to observe in solid-state systems. Not only only do these systems allow the investigation of interesting quantum phases, but they offer unique opportunities for the study of non-equilibrium dynamics.
I will give an introduction to these ideas, taking examples from our recent work in both coherent and dissipative many-body dynamics. In particular, I will comment on new ideas for measuring the growth of entanglement in quantum many-body systems during non-equilibrium dynamics, and also on the decoherence of different many-body states in the presence of heating mechanisms. In these systems, heating processes are intrinsically non-equilibrium, and as a result, different many-body states can respond very differently to the same heating mechanism.
