摘要:

两种可区分的玻色气体的混合物,被限制在一个环势的旋转特性提供了新的物理效应,我们在这项研究中证明。持久电流被证明是稳定的范围内的人口之间的不平衡的两个组件在低角动量。在较高的角动量值下,即使第二种原子的少量混合物也会使持续电流变得非常脆弱。

英文摘要:

The rotational properties of a mixture of two distinguishable Bose gases that are confined in a ring potential provide novel physical effects that we demonstrate in this study. Persistent currents are shown to be stable for a range of the population imbalance between the two components at low angular momentum. At higher values of the angular momentum, even small admixtures of a second species of atoms make the persistent currents highly fragile.
