论文摘要
我们已经观察到了伪磁场的影响，该磁场源自自旋轨道耦合的极性类似物（TE $ - $ TM拆分）对环形微博的偏振子冷凝物的影响。从凝结物光致发光的线性极化测量中可以看出，该效果在环周围产生了稳定的四叶图。发现这种模式源自环中的空腔电位，能量松弛和TE-TM分裂的相互作用。我们的观察结果与耗散的一维旋转旋转器 - 彼得斯基方程与TE-TM分裂能量进行了比较，该方程式显示出良好的定性一致性。
We have observed the effect of pseudo magnetic field originating from the polaritonic analog of spin-orbit coupling (TE$-$TM splitting) on a polariton condensate in a ring-shaped microcavity. The effect gives rise to a stable four-leaf pattern around the ring as seen from the linear polarization measurements of the condensate photoluminescence. This pattern is found to originate from the interplay of the cavity potential, energy relaxation, and TE-TM splitting in the ring. Our observations are compared to the dissipative one-dimensional spinor Gross-Pitaevskii equation with the TE-TM splitting energy which shows good qualitative agreement.
