The most direct approach for characterizing the quantum dynamics of a strongly interacting
system is to measure the time evolution of its full many-body state. Despite the conceptual …

Statistical mechanics underlies our understanding of macroscopic quantum systems. It is
based on the assumption that out-of-equilibrium systems rapidly approach their equilibrium …
