| Abstract: | We present a family of the solutions of two-component Bose--Einstein condensates with time-dependent scattering length by means of multiple-scale method. Our numerical calculations show that the collision properties (the position, the time, and the frequency of the collision) between two solitons can be controlled by the time-dependent interspecies scattering length.Meanwhile, we also find that the amplitude of the solitons is close relatedto the time-dependent interspecies scattering length. |
