Description

Localization, or its absence, is a fundamental distinguishing feature of any many-body system, affecting the ways that mass, charge, energy, and momentum move and respond to inhomogeneity. Decades of work in both classical and quantum matter have classified circumstances in which transport is ballistic, diffusive, localized, or something stranger. A current frontier in this venerable field is the study of transport in driven matter, in which some control parameter is made explicitly time-dependent. Subjecting a quantum system to a time-dependent Hamiltonian can generate a rich array of localizing and delocalizing dynamics. I will discuss results from a sequence of recent cold-atom experiments on kicked and driven quantum matter, highlighting data on anomalous transport, the interplay between dynamical and disorder-induced localization, and quantum simulation of integer quantum Hall matter illuminated by light of arbitrary polarization.
