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…

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…
