摘要: Considering the time-dependent interspecies interactions, we study collision properties of bright-bright solitons in two species Bose-Einstein condensates with harmonic external potentials. It is shown that behaviors can be controlled by adjusting strength interaction and transverse trapping frequency potential. Interestingly, separate merge into a single bound complex due to stronger attractive interactions. Especially, transmission obtained from not only but also repulsive interaction, different previous theory. When exponentially decreased, reflection-transmission transition observed for interaction. Meanwhile, an experimental protocol designed observe currently conditions.
