Experimental Realization of the Many-Body Quantum Kicked Rotor

ORAL

Abstract

The kicked rotor is a paradigmatic model of classical and quantum chaos; dynamical localization in the quantum kicked rotor contrasts sharply with classically-expected ergodicity. Despite a quarter-century of atom-optical experimental studies, the effect of interactions on the dynamically localized state has remained unexplored.  We report the experimental realization of a many-body kicked quantum rotor with Feshbach-tunable interparticle interactions. As interactions are increased from zero, we observe the emergence of many-body dynamical delocalization.
