论文摘要
我们跟踪激发量极化凝结物的轨道自由度，限制在光学陷阱中，并揭示脉冲周期性激发方案中持续的环形极性电流的随机切换。在一个椭圆形陷阱中，椭圆形陷阱，较低的能量极性状态在极性状态下是两个精致的分布和两个精致的分布和夜间的既既夜间''。在随机状态下，在多个激发脉冲密度分布上平均沿方位角匀浆，而从干扰实验中提取的加权相在陷阱的中心周围变化时，从干扰实验中提取的加权相互相补偿。用补充控制光脉冲打破系统的互惠使系统可以将系统从随机状态转换为任意极化循环的确定性态度。
We keep track of the orbital degree of freedom of an exciton polariton condensate, confined in an optical trap, and reveal the stochastic switching of persistent annular polariton currents in the pulse-periodic excitation regime.In an elliptic trap, the low-lying in energy polariton current states are inherent in a two-petalled density distribution and swirling phase. In the stochastic regime, the averaged over multiple excitation pulses density distribution gets homogenised in the azimuthal direction, while the weighted phase extracted from interference experiments experiences two compensating each other jumps, when varying around the center of the trap. Breaking the reciprocity of the system with a supplemental control optical pulse makes it possible to switch the system from the stochastic regime to the deterministic regime of an arbitrary polariton circulation.
