Abstract: The quantum kicked rotor is a paradigmatic model system in quantum physics. As a driven quantum system, it features dynamical localization, specifically Anderson localization in momentum space. However, the interacting many-body kicked rotor is believed to break localization. Here, we present evidence for many-body dynamical localization for the Lieb-Liniger version of the many-body quantum kicked rotor. After some initial evolution, the momentum distribution of interacting quantum-degenerate bosonic atoms in one-dimensional geometry, kicked hundreds of times by means of a pulsed sinusoidal potential, stops spreading. Our results shed light on the boundary between the classical, chaotic world and the realm of quantum physics. Editor's summary: Interactions in a many-body system often lead to thermalization. However, it has recently been theoretically predicted that an interacting one-dimensional bosonic gas subject to periodic "kicks" localizes instead of thermalizing. Guo et al. realized such a system using quantum-degenerate samples of cesium atoms and tuned the interaction strength from noninteracting to strongly interacting, finding localization in both limits. —Jelena Stajic [ABSTRACT FROM AUTHOR]
