Symmetry protected skyrmions in 3D spin-orbit coupled Bose gases
Guanjun Chen, Tiantian Li, Yunbo Zhang
We present a variational study of pseudo-spin Bose gases in a harmonic trap with weak 3D spin-orbit coupling of $\bmsigma\cdot\mathbf{p}$ type. This spin-orbit coupling mixes…

Nonlinear Atom-Photon Interaction Induced Population Inversion and Inverted Quantum Phase Transition of Bose-Einstein Condensate in an Optical Cavity
Xiuqin Zhao, Ni Liu, J-Q Liang
In this paper we explore the rich structure of macroscopic many-particle quantum states for Bose- Einstein condensate in an optical cavity with the tunable nonlinear atom-photon in…
