旋转双组分玻色-爱因斯坦凝聚体中的巨涡旋和Skyrmion

Giant vortex and Skyrmion in a rotating two-species Bose-Einstein condensate

Shi-Jie Yang, Quan-Sheng Wu, Sheng-Nan Zhang, Shiping Feng

摘要:

对简谐势约束下的旋转两组分玻色凝聚体进行了数值模拟。每个物种的粒子数是不相等的。当旋转速度超过临界值时,大多数物种位于势的中心,而少数物种被推到外围,形成一个巨大的漩涡孔来容纳大多数物种。在两种粒子的界面处形成了一个新的环形Skyrmion。

英文摘要:

Numerical simulations are performed for a rotating two-species Bose condensate confined by a harmonic potential. The particle numbers of each species are unequal. When the rotational speed exceeds a critical value, the majority species reside in the center of the potential while the minority species is pushed out to the outskirts, forming a giant vortex hole to contain the majority species. A novel annular Skyrmion forms at the interface of the two species.
