研究了自旋为1的玻色-爱因斯坦凝聚体与单向环形腔色散耦合时的物质波双稳性。一个独特的特征是不同模式的物质场之间的布居交换是通过自旋交换碰撞完成的。我们发现，原子自旋混合和腔场之间的相互作用，可以导致一个强大的物质波非线性，使物质波的双稳态在单光子水平的腔中是可以实现的。
We study matter-wave bistability in a spin-1 Bose-Einstein condensate dispersively coupled to a unidirectional ring cavity. A unique feature is that the population exchange among different modes of matter fields is accomplished via spin-exchange collisions. We show that the interplay between the atomic spin mixing and the cavity light field can lead to a strong matter-wave nonlinearity, making matter-wave bistability in a cavity at the single-photon level achievable.
