论文摘要
我们研究了二维(2D)Rashba旋转轨道(SO)耦合自旋1 Bose-1 Bose-Einstein冷凝物(BEC)中的固定涡旋溶液(BEC)。通过引入广义动量运算符,可以精确求解系统的线性版本,其解决方案是一组Bessel涡流。基于线性版本解决方案,完整非线性系统的固定涡流解决方案完全由变化近似构建和确定。结果表明,变异结果与数值相吻合。通过变异结果,详细讨论了固定涡流解决方案,稳定性和单位BLOCH矢量纹理之间的涡流基态相位相变。结果有可能在实验中实现。
We investigate the stationary vortex solutions in two-dimensional (2D) Rashba spin-orbit (SO) coupled spin-1 Bose-Einstein condensate (BEC). By introducing the generalized momentum operator, the linear version of the system can be solved exactly and its solutions are a set of the Bessel vortices. Based on the linear version solutions, the stationary vortex solutions of the full nonlinear system are constructed and determined entirely by the variational approximation. The results show that the variational results are in good agreement with the numerical ones. By means of the variational results, the vortex ground state phase-transition between the stationary vortex solutions, stability, and the unit Bloch vector textures are discussed in detail. The results have the potential to be realized in experiment.
