Double-Layer Bose-Einstein Condensates with Large Number of Vortices
Hui Zhai, Qi Zhou, Rong Lv +1
In this paper we systematically study the double layer vortex lattice model, which is proposed to illustrate the interplay between the physics of a fast rotating Bose-Einstein cond…
Skyrmion Excitation in Two-Dimensional Spinor Bose-Einstein Condensate
Hui Zhai, WeiQiang Chen, Zhan Xu +1
We study the properties of coreless vortices(skyrmion) in spinor Bose-Einstein condensate. We find that this excitation is always energetically unstable, it always decays to an uni…
Macroscopic Quantum Tunnelling in Rotating Bose-Einstein Condensates
Yuan-Xiu Miao, Hui Zhai, Hong-Yu Yang +1
In this paper we investigate the macroscopic quantum tunnelling and the phase coherence property of the rotating Bose-Einstein condensates in both static and dynamic cases by using…
Ground state properties of a trapped few-Boson system under rotation --beyond the "lowest Landau level" approximation--
Xiaji Liu, Hui Hu, Lee Chang +1
We consider a harmonically trapped few-Boson system under rotation and investigate the ground state properties beyond the usual ``lowest Landau level'' approximation by using exact…
Quantum coherence of double-well BEC: a SU(2)-coherent-state path-integral approach
Yi Zhou, Hui Zhai, Rong Lü +2
Macroscopic quantum coherence of Bose gas in a double-well potential is studied based on SU(2)-coherent-state path-integral. The ground state and fluctuations around it can be obta…
Fragmented Condensate Ground State of Trapped Weakly Interacting Bosons in Two Dimensions
Xia-Ji Liu, Hui Hu, Lee Chang +3
The ground state and its structure for a rotating, harmonically trapped N-Boson system with a weak repulsive contact interaction are studied as the angular momentum L increases up…
