Floquet engineering for quantum simulation — •Marín Bukov — Max Planck Institute for the Physics of Complex Systems

This lecture introduces periodically driven systems, with particular emphasis on applications in AMO-based quantum simulators. After introducing Floquet's theorem, we will focus on the physical intuition behind it and discuss how to design effective Hamiltonians with prescribed properties. In particular, we will discuss how to use strong high-frequency periodic drives to stabilize unstable equilibria, localize quantum matter, and engineer artificial magnetic fields. Time permitting, we will mention the primary role of periodic drives for the investigation of energy absorption and thermalization in closed interacting quantum systems, and introduce Floquet time crystals -- a nonequilibrium phase of matter with no equilibrium counterpart.

Keywords: periodically driven systems; Floquet engineering; nonequilibrium dynamics; artificial magnetic fields -- time crystals; energy absorption -- heating -- thermalization
