Giant vortex and skyrmion in a rotating two-species Bose-Einstein condensate
Numerical simulations are performed for a rotating two-species Bose-Einstein condensate confined by a harmonic potential. The particle numbers of the two 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 …
