Spin-only dynamics of the multi-species nonreciprocal Dicke model
Joseph Jachinowski, Peter B. Littlewood
The Hepp-Lieb-Dicke model is ubiquitous in cavity quantum electrodynamics, describing spin-cavity coupling which does not conserve excitation number. Coupling the closed spin-cavit…

Theory of two-component superfluidity of microcavity polaritons
A. Nafis Arafat, Oleg L. Berman, Godfrey Gumbs +1
We develop a microscopic mean-field theory describing the coexistence of Bose-Einstein condensates of upper and lower polaritons (UP/LP) in a semiconductor microcavity. Incorporati…

Optical probes of coherence in two dimensional Bose gases of polaritons
Joseph Jachinowski, Hassan Alnatah, David W. Snoke +1
Due to their photonic components, exciton-polariton systems provide a convenient platform to study the coherence properties of weakly-interacting Bose gases. In particular, optical…
