Since the seminal work of Fishman, Grempel and Prange on the kicked rotator[1], it is known that periodically driven - otherwise known as Floquet - systems can exhibit ’dynamical localization’: a variant of Anderson localization in which the particle is localized not in real, but in momentum space. In the past decade it became clear that Anderson localization in real space is robust against sufficiently weak interactions, leading to a phenomenon called many-body localization. It is therefore a natural question to ask whether the dynamical localization, exhibited by periodically driven free particles, also has an interacting analogue. In this talk we review recent results regarding this question and compare them to our own results acquired through large-scale numerical simulations.
