Controllable matter-wave switchers with vector Bose-Einstein solitons

We show the possibility of producing matter-wave switching devices by using Manakov interactions between matter wave solitons in two-species Bose-Einstein Condensates (BEC). Our results establish the experimental parameters for three interaction regimes in two-species BECs: symmetric and asymmetric splitting, down-switching and up-switching. We have studied the dependence upon the initial conditions and the kind of interaction between the two components of the BECs.
