旋量为2的玻色-爱因斯坦凝聚体中的涡旋拼接

Vortex Tiling in a Spin-2 Spinor Bose-Einstein Condensate

Michikazu Kobayashi, Yuki Kawaguchi, Masahito Ueda

摘要:

我们指出,内部自旋对称的序参量表现在核心的分数涡旋在实空间中没有自旋轨道耦合。这种对称性破缺源于拓扑约束和核内外序参量自旋对称性之间的可交换性。我们的预测可以应用于探测旋转自旋为2的$^{87}$ Rb凝聚体作为非圆涡核在双轴双旋态下的循环序参量。

英文摘要:

We point out that the internal spin symmetry of the order parameter manifests itself at the core of a fractional vortex in real space without spin-orbit coupling. Such symmetry breaking arises from a topological constraint and the commensurability between spin symmetries of the order parameters inside and outside the core. Our prediction can be applied to probe the cyclic order parameter in a rotating spin-2 $^{87}$Rb condensate as a non-circular vortex core in a biaxial nematic state.
