Floquet Engineering with Ultracold Lithium in Optical Lattices


Floquet engineering is a versatile tool that uses periodic driving of a quantum system to build novel many-body quantum states with drive-dependent properties. In this thesis I will detail experiments performed in the Weld group which explore a many-body Floquet system consisting of tunably-interacting ultracold atoms in an optical lattice amplitude-modulated at up to a thousand percent. I will discuss experiments in which we use Floquet engineering to coherently control long-range quantum transport in hybridized Floquet-Bloch bands. I will also discuss our use of a double quench protocol to experimentally control and quantitatively characterize Floquet prethermalization associated with a periodic generalized Gibbs ensemble.
