Vector Solitons and Soliton Collisions in Two-Component Bose–Einstein Condensates
Xunxu Liu, Zhang Xiao-Fei, Peng Zhang
With realistic parameters, both analytical and computational studies demonstrate the feasibility of forming bright-bright vector solitons in a self-repulsive two-component Bose-Einstein condensate with attractive inter-component interaction. Moreover, the stability of such solitons is confirmed by direct numerical simulations, by a Bogoliubov spectrum analysis, and by examining the collisions between two vector solitons. Our results are of considerable experimental interest.
