Phase Transitions in Open Dicke Model: a degenerate perturbation theory approach
Wenqi Tong, H. Alaeian, F. Robicheaux
We study the steady-state behavior of the open Dicke model, which describes the collective interaction of spin- particles with a lossy, quantized cavity mode and exhibits…

Qualitatively altered driven Dicke superradiance in extended systems due to infinitesimal perturbations
Wenqi Tong, F. Robicheaux
The driven Dicke model, with interesting quantum phases induced by parameterized driving, has been intensively studied in cavities, where permutation symmetry applies due to the at…
