| Abstract: |
A VIRTUAL AMO SEMINAR presented in a Zoom meeting vetted by CQuIC. See https://sites.google.com/stanford.edu/virtual-amo-seminar/schedule for the meeting link. Even in the absence of a precise microscopic description, classical hydrodynamics provides a powerful framework for characterizing the macroscopic behavior of conserved densities, such as energy. Understanding whether and how it emerges in the late-time dynamics of many-body quantum systems has remained an enduringly hard question. In this talk, I will describe on-going experiments exploring the emergence of hydrodynamics in strongly interacting dipolar spin ensembles; in particular, we observe dynamics whose long-time limit is related to, but fundamentally distinct from ordinary diffusion. This distinction arises from the complex interplay between long-range interactions, positional disorder, and on-site random fields. Finally, time permitting, I will briefly describe a new class of many-body quantum teleportation circuits, which enable one to distinguish between various classes of quantum information dynamics as well as decoherence.
