摘要：
The dynamics of two-component Bose-Einstein condensates (BECs) in a double-well potential is studied here. Interspecies (or component-component) couplings are taken into account. As a consequence of the couplings, more fixed points may appear in the BECs. We analyze the stability of the system around some special fixed points that are independent of the couplings. A critical interspecies coupling constant below which fixed points are stable is presented and analyzed. Numerical simulation of the dynamics of the two-component BECs is also presented and discussed.
