我们研究了光腔中光场耦合的双组分玻色-爱因斯坦凝聚体与混相-不混相条件相关的多稳定性。在强不混相条件下，系统表现出多种密度结构，包括分离态、条纹态以及它们的共存。双组分凝析液的这些空间结构产生了多重稳定性，显著地改变了与腔泵强度相关的滞回曲线。我们提出了一种变分方法来证实我们的数值结果。
We examine the multistability associated with miscibility-immiscibility conditions for a two-component Bose-Einstein condensate coupled to the light field in an optical cavity. For a strongly immiscible condition, the system exhibits a variety of density structures, including a separated state, a stripe state, and their coexistence. The multistability arises from these spatial structures of the two-component condensate, which significantly alter the hysteresis curve with respect to the intensity of cavity pumping. We present a variational approach to confirm our numerical results.
