A spin-Meissner effect occurs when the photoluminescence energy is dependent on interactions of otherwise magnetically sensitive particles. Under such a condition, the Zeeman energy splitting becomes zero when the chemical potentials for individual spin components of a spinor polariton condensate are equal or synchronized. Herein, we explore the types of topological spin-Meissner (TSM) states in the formation of a spinor dark soliton in semiconductor microcavities. The effects of nonlinear spin-anisotropic interactions between polaritons, spin-flipping rate from the introduced defects, and energy splitting are theoretically investigated. We observe that, below a critical energy splitting for a given pump power, multistable TSM states exist. However, above a critical energy splitting, the two spin components of the dark soliton pair become desynchronized.

非平衡极化子冷凝物中的拓扑自旋-Meissner态

当光致发光能量取决于磁性敏感粒子的相互作用时，就会发生自旋Meissner效应。在这种条件下，当自旋极化子冷凝物的各个自旋成分的化学势相等或同步时，塞曼能分裂为零。在这里，我们探索在半导体微腔中形成自旋暗孤子的拓扑自旋Meissner（TSM）状态的类型。理论上研究了极化子之间的非线性自旋各向异性相互作用，引入缺陷的自旋翻转速率以及能量分裂的影响。我们观察到，在给定泵浦功率的临界能量分配之下，存在多稳态TSM状态。但是，在关键的能量分裂之上，
