Quantum Criticality of Liquid-Gas Transition in a Binary Bose Mixture
Li He, Haowei Li, Wei Yi +1
Quantum liquid, in the form of a self-bound droplet, is stabilized by a subtle balance between the mean-field contribution and quantum fluctuations. While a liquid-gas transition i…
First-order Bose-Einstein condensation with three-body interacting bosons
Hui Hu, Zeng-Qiang Yu, Jia Wang +1
Bose-Einstein condensation, observed in either strongly interacting liquid helium or weakly interacting atomic Bose gases, is widely known to be a second-order phase transition. He…
Normal-Superfluid Phase Separation in Spin-Half Bosons at Finite Temperature
Li He, Peipei Gao, Zeng-Qiang Yu
For pseudospin-half bosons with inter-spin attraction and intra-spin repulsion, normal phase and Bose condensed phase can coexist at finite temperature. The homogeneous system is u…
Collective excitation of a trapped Bose-Einstein condensate with spin-orbit coupling
Li Chen, Han Pu, Zeng-Qiang Yu +1
We investigate the collective excitations of a Raman-induced spin-orbit coupled Bose-Einstein condensate confined in a quasi one-dimension harmonic trap using the Bogoliubov method…
Landau's criterion for an anisotropic Bose-Einstein condensate
Zeng-Qiang Yu
In this work, we discuss the Landau's criterion for anisotropic superfluidity. To this end, we consider a point-like impurity moving in a uniform Bose-Einstein condensate with eith…
Superfluid Density of a Spin-orbit Coupled Bose Gas
Yi-Cai Zhang, Zeng-Qiang Yu, Tai Kai Ng +3
We discuss the superfluid properties of a Bose-Einstein condensed gas with spin-orbit coupling, recently realized in experiments. We find a finite normal fluid density at zer…
