Exploring quantum dynamics with ultracold lithium in optical lattices

POSTER

Abstract

Ultracold lithium atoms in periodically modulated optical lattices serve as an ideal experimental platform for probing the dynamics of driven quantum systems. We report recent progress on several experiments along these lines, including Poincaré phase-space portraits of transport in driven inhomogeneous lattice gases and many-body prethermalization and delocalization in an interacting quantum kicked rotor. We describe future prospects for investigation of time-domain condensed matter physics, event-horizon dynamics of atoms with relativistic dispersion in a driven optical cavity, and quantum heat engines.
