| Giant vortex and Skyrmion in a rotating two-species Bose-Einstein condensate (2007) | |||||||||
Abstract | |||||||||
| 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.. Comment: 5 pages, 5 figures | |||||||||
