玻色-爱因斯坦凝聚体的拓扑相和循环态

Topological phases and circulating states of Bose-Einstein condensates

K. G. Petrosyan, L. You

摘要:

我们表明,量子拓扑效应预测Aharonov和Casher(AC效应)[物理。53,319(1984)]可用于产生磁俘获原子玻色-爱因斯坦凝聚体(BEC)的循环态。提出了一种简单的实验装置,该装置是基于多连通的几何结构,如环形阱或由蓝失谐激光箍缩的磁阱。我们在当前的原子BEC实验中给出了这种效应的数值估计,并指出了相关的量子化循环态的一些有趣的性质。

英文摘要:

We show that the quantum topological effect predicted by Aharonov and Casher (AC effect) [Phys. Rev. Lett. 53, 319 (1984)] may be used to create circulating states of magnetically trapped atomic Bose-Einstein condensates (BEC). A simple experimental setup is suggested based on a multiply connected geometry such as a toroidal trap or a magnetic trap pinched by a blue-detuned laser. We give numerical estimates of such effects within the current atomic BEC experiments, and point out some interesting properties of the associated quantized circulating states.
