Nonclassical Many-Body Superradiant States with Interparticle and Spin-Momentum Entanglement
Jarrod T. Reilly, Gage W. Harmon, John Drew Wilson +2
We present a cross-cavity system in which steady-state superradiance is achieved using solely collective dissipative dynamics. Two cavities symmetrically couple an ensemble of four…

Collective Excitations of Dissipative Time Crystals
Gage W. Harmon, Giovanna Morigi, Simon B. Jäger
We study the dynamics of atoms interacting periodically with a dissipative optical cavity and employ Floquet theory to analyze their low-frequency behavior. By means of an effectiv…

Dynamical phases of a BEC in a bad optical cavity at optomechanical resonance
Gage W. Harmon, Giovanna Morigi, Simon B. Jäger
We study the emergence of dynamical phases of a Bose-Einstein condensate that is optomechanically coupled to a dissipative cavity mode and transversally driven by a laser. We focus…
