IQP Seminar: Programing light-matter interactions in cavity-quantum electrodynamics

Abstract:

Cavity-quantum electrodynamics offers a new avenue for quantum simulations, where photons can be used as mediators of an atom-atom interaction with all-to-all connectivity, as well as information carriers on the atomic system contained in the cavity mode. In this presentation, I will report on our progresses to control and program light-matter interaction in these settings, going beyond the standing or traveling wave modes arising from the geometry. I will first present the implementation of controlled disorder, realizing a family of random spin models with disorder-controlled magnetic properties. I will then describe a cavity-microscope device allowing to control locally the light-matter coupling though a combination of Floquet engineering and adaptative optics. Last, I will present the prospects open by this technology for the quantum simulation of the Sachdev-Ye-Kitaev model, a paradigmatic example of holographic matter.
