Armand Niederberger, Thomas Schulte, Jan Wehr, Maciej Lewenstein, Laurent Sanchez-Palencia, Krzysztof Sacha

摘要:

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的玻色-爱因斯坦凝聚体,类似于相应的影响建立XY自旋模型。我们表明,随机拉曼耦合诱导两个BEC之间的π/2的相对相位和效果是强大的。我们证明了它在1D,2D和3D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。

英文摘要:

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 two BECs and that the effect is robust. We demonstrate it in 1D, 2D and 3D at T=0 and present evidence that it persists at small T>0. Applications to phase control in ultracold spinor condensates are discussed.
