Davisson-Germer Prize in Atomic or Surface Physics: Exciting 1D Bose gases

Experiments with nearly integrable quantum systems taken out of equilibrium have made clear that conventional statistical mechanics does not always describe the steady state of an isolated many-body system. These experiments have deepened our understanding of what it means for any quantum system to thermalize. I will briefly explain the two previous sentences and then touch on the frontier of experiment and theory in out-of-equilibrium nearly integrable many-body quantum systems, focusing on our work with 1D Bose gases.
