论文摘要
我们研究了在空间局部的非共振光学泵送下，在圆柱形微骨腔中的环形偏振子冷凝物中激子极化子的超氟电流的形成。由于极性冷凝物是强烈的非平衡系统，因此在柱边缘形成的极化剂的诱捕潜力和光学诱导的不一致的激子的储层在通常的情况下是复杂的。它的假想部分包括泵中的空间分布的增益和冷凝水中极性子的损失。我们表明，工程在微柱平面中的增益损失平衡可访问北极凝结物的激发态。我们在复杂的环形陷阱电势中在理论上和实验形成了理论上和实验形成涡旋。
We study formation of superfluid currents of exciton polaritons in annular polariton condensates in a cylindrical micropillar cavity under the spatially localised nonresonant optical pumping. Since polariton condensates are strongly nonequilibrium systems, the trapping potential for polaritons, formed by the pillar edge and the reservoir of optically induced incoherent excitons, is complex in general case. Its imaginary part includes the spatially distributed gain from the pump and losses of polaritons in the condensate. We show that engineering the gain-loss balance in the micropillar plane gives access to the excited states of the polariton condensate. We demonstrate both theoretically and experimentally formation of vortices in double concentric ring polariton condensates in the complex annular trap potential.
