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…
Mediated Interactions and Damping Effects in Superfluid Mixtures of Bose and Fermi Gases
Dong-Chen Zheng, Yu-Xin Liao, Wen Lin +1
We investigate the homogeneous superfluid mixtures of Bardeen-Cooper-Schrieffer~(BCS) superfluid originating from pairing two-species fermionic atoms and superfluidity stemming fro…
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…
Hartree-Fock approximation for bosons with symmetry-adapted variational wave functions
B. R. Que, J. M. Zhang, H. F. Song +1
The Hartree-Fock approximation for bosons employs variational wave functions that are a combination of permanents. These are bosonic counterpart of the fermionic Slater determinant…
Quantum Triticality of Bosonic Atomic-Molecular Mixtures with Feshbach Coupling
Yuan-Hong Chen, Dong-Chen Zheng, Renyuan Liao
We develop a functional integral formulation for a homogeneous bosonic atomic-molecular mixture with Feshbach coupling in three-spatial dimensions. Taking phase stability into acco…
