Description

Subjecting a quantum system to a time-dependent Hamiltonian can generate a rich array of dynamics and phases of matter. I will discuss results from a sequence of recent cold-atom experiments on kicked and driven quantum matter, highlighting data on anomalous transport, nonequilibrium phase diagrams, quantum thermodynamics, and the interplay between dynamical localization and Anderson localization.
