Floquet-Aubry-André Localization in Driven Quasiperiodic Optical Lattices

Optical lattice experiments are an ideal tool for exploring the interplay among disorder-induced localization, interaction-induced localization, and dynamical localization. We discuss experiments probing the response of a quantum gas in a tunable bichromatic lattice to strong phasonic [1] and dipolar modulation. Independent tuning of the quasi-disorder strength and the effective tunneling enables exploration of a wide parameter space lying between limiting cases such as Aubry-André localization (for zero drive strength) and dynamical localization (for a dipolar drive at zero quasi-disorder strength).
