我们提出并分析了一个一般机制的无序诱导秩序的两个组件玻色-爱因斯坦凝聚体，类似于相应的影响建立XY自旋模型。我们发现，一个随机的拉曼耦合诱导两个BEC之间的相对相位π/2，效果是强大的。我们证明了它在一个，两个和三个维度在T=0，目前的证据表明，它仍然存在于小T>0。讨论了超冷旋量凝聚在相位控制中的应用。
We propose and analyze a general mechanism of disorder-induced order in two-component Bose-Einstein condensates, analogous to corresponding effects established for XY spin models. We show that a random Raman coupling induces a relative phase of pi/2 between the two BECs and that the effect is robust. We demonstrate it in one, two, and three dimensions at T=0 and present evidence that it persists at small T>0. Applications to phase control in ultracold spinor condensates are discussed.
