Quantum thermalization, localization, and constrained dynamics with interacting ultracold atoms

FOR 5522 investigates the out-of-equilibrium physics of closed quantum many-body systems and their thermalization properties. We use a combined effort of experiments with ultracold atoms in optical lattices and theoretical approaches. Our team involves researchers from the Universities of Augsburg, Göttingen, München, and Tübingen, Technical University of Munich, the Max-Planck Institute for Quantum Optics, Garching, and the Max-Planck Institute for the Physics of Complex Systems, Dresden, as well as two Mercator fellows from the University of Ljubljana, Slovenia, and Stanford University, U.S.A.
