摘要: Following our previous work [J. Ieda, T. Miyakawa and M. Wadati: cond-mat/0404569] on a novel integrable model describing soliton dynamics of an F =1 spinor Bose–Einstein condensate, we discuss in detail the properties multi-component system with spin-exchange interactions. The exact multiple bright solutions are obtained for where mean-field interaction is attractive ( c 0 < 0) ferromagnetic 2 0). A complete classification one-soliton solution respect to spin states explicit formula two-soliton presented. For solitons polar state, there exists variety different shaped including twin peaks. We show that “singlet pair” density can be used distinguish those energetically degenerate solitons. also analyze collisional effects between same or state(s) by computing asymptotic forms their initial final states. result reveals th...
