摘要:

本文对具有拉曼诱导自旋轨道角动量耦合的环形玻色-爱因斯坦凝聚体进行了理论研究。我们分析了不同物理参数下系统的基态结构,并在相图上揭示了条纹相内的特殊精细结构。我们证明了存在的预测条纹子相位在很宽的物理参数范围内,其可追溯性,通过物理观测,并比较结果与几种常用的变分近似。我们还表明,预测的条纹相的子阶段,可以观察到在实验上可实现的条件。

英文摘要:

We report on a theoretical study of a ring-shaped Bose-Einstein condensate with Raman-induced spin-orbital-angular-momentum coupling. We analyze the structure of the ground-state of the system depending different physical parameters and reveal a peculiar fine structure within the stripe phase on the phase diagram. We demonstrate the existence of the predicted stripe sub-phases within a wide range of physical parameters, their traceability through physical observables, and compare the results with several commonly used variational approximations. We also show that predicted sub-phases of the stripe phase can be observed within experimentally realizable conditions.
