论文摘要
最近，自旋轨道耦合的玻色子凝结物（BEC）中的条纹相吸引了很多关注，因为它们被鉴定为超溶相。在本文中，我们利用实验可以触及的参数，并从理论上表明，可以在旋转轨道 - 角度 - 角度 - 摩托车（SOAMC）BEC中实现具有较大条纹间距和高条纹对比度的环形条纹阶段。除了使用Gross-Pitaevskii数值模拟外，我们还开发了一个变异的ANSATZ，该变量捕获了一阶的基本相互作用效果，而这是先前文献中使用的ANSATZ中不存在的。我们的工作应为实验中的SOAMC BEC中的直接观察条纹阶段打开可能性。
Recently, stripe phases in spin-orbit coupled Bose-Einstein condensates (BECs) have attracted much attention since they are identified as supersolid phases. In this paper, we exploit experimentally reachable parameters and show theoretically that annular stripe phases with large stripe spacing and high stripe contrast can be achieved in spin-orbital-angular-momentum coupled (SOAMC) BECs. In addition to using Gross-Pitaevskii numerical simulations, we develop a variational ansatz that captures the essential interaction effects to first order, which are not present in the ansatz employed in previous literature. Our work should open the possibility toward directly observing stripe phases in SOAMC BECs in experiments.
