Floquet Engineering and Thermodynamics with Ultracold Lithium

POSTER

Abstract

We present results of recent experiments on quantum thermodynamics and thermalization using ultracold lithium BECs. We report the first experimental observation and characterization of the quantum boomerang effect, using an atom-optics kicked rotor realized with a pulsed optical lattice. Separately, we discuss progress towards studying quantum thermodynamic engines and realizing trapped-atom interferometry in “magic” Floquet-Bloch bands.
