Cold-atom Quantum Emulation of Floquet States, Nonlinear Bloch Oscillations, and Quasicrystals

POSTER

Abstract

Ultracold lithium atoms in optical lattices provide a versatile platform for investigation of non-equilibrium quantum systems and many-body condensed matter phenomena. We report on experimental characterization of a Floquet phase diagram using bosonic lithium in a strongly-driven optical lattice. Additionally, we present experimental studies of nonlinear real-space Bloch oscillations and progress towards creation of tunable quasicrystalline matter using quasiperiodic optical potentials.
