研究了共心双环势阱中，自旋轨道耦合下的玻色爱因斯坦凝聚体的基态结构，发现随着自旋轨道耦合的变化，耦合系统呈现出丰富的基态结构。仅在一个方向加入自旋轨道耦合并随之增大时，系统基态密度呈现不均匀的角相分离分布，其相图显示它们仍然为驻波态；随着另一个垂直方向自旋轨道耦合强度的引入并逐渐增大到与原来方向相同，形成各向同性自旋轨道耦合时，系统基态密度逐渐形成均匀角相分离分布，从相位图中研究发现，各向同性自旋轨道耦合作用使系统基态产生了大量涡旋。

The ground state structure of spin?orbit?coupled Bose?Einstein condensates in concentrical dual?ring potential well is studied,with changing of the spin?orbit?coupled,multiple ground state structures are appearing in the coupled system. If the spin?orbit?coupled is added increasingly only in one direction,inhomogeneous distribution of the azimuthal phase separation is appeared in the ground state density,however it is still the stating wave from the phase graph showing. The other spin?orbit?coupled strength is added increasingly in vertical direction until the same with the original direction,when the isotropy of spin?orbit?coupled is shaped,homogeneous distribution of the azimuthal phase separation is appeared gradually in the ground state density. Investigation from phase diagram shows that a large number of vortexes in ground state system are generated by the func?tion of isotropy spin?orbit?coupled.
