Tuning Density and Spin Ordering of Degenerate Fermi Gases in an Optical Cavity
Wei Qin, Yuan-Hong Chen, Renyuan Liao
We investigate a spin-degenerate Fermi gas coupled to a high-finesse optical cavity, where the competition between scalar and vectorial couplings is controlled by the relative pola…
Phase transition, phase separation and mode softening of a two-component Bose-Einstein condensate in an optical cavity
Jia-Ying Lin, Wei Qin, Renyuan Liao
We investigate the superradiant phase transition in a two-component Bose-Einstein condensate with distinct atomic detunings, confined in an optical cavity and driven by a transvers…
Theoretical Exploration of Phase Transitions in a Cavity-BEC System with Two Crossed Optical Pumps
Wei Qin, Dong-Chen Zheng, Zhao-Di Wu +2
We consider a Bose-Einstein condensation (BEC) inside an optical cavity and two crossed coherent pump fields. We determine the phase boundary separating the normal superfluid phase…
Nonreciprocal Superradiant Phase Transitions and Multicriticality in a Cavity QED System
Gui-Lei Zhu, Chang-Sheng Hu, Hui Wang +3
We demonstrate the emergence of nonreciprocal superradiant phase transitions and novel multicriticality in a cavity quantum electrodynamics (QED) system, where a two-level atom int…
