Effects of interaction in the kicked Auby-André-Harper model
ORAL
Abstract
Ultracold atoms in a bichromatic lattice provide an excellent platform for the study of disordered systems, in particular naturally realizing the Aubry-André-Harper (AAH) model. We recently reported an experimental realization of the kicked Aubry-André-Harper model [1], wherein the pseudo-disorder potential in the AAH model is periodically pulsed. By utilizing a Floquet apodization technique, we explored the phase diagram of the kicked AAH model and observed a broad regime of anomalous transport. This talk will build on these results by elucidating the effects of the relative phase of the bichromatic lattice, interband heating, finite pulse widths, and, most importantly, interparticle interactions, all of which have the potential to alter the anomalous localization behavior.
