论文摘要
从理论上讲，我们研究了不一致的激发储层如何影响驱动式极化流体的超流体特性。在没有储层的情况下，在静止和静态缺陷流动的流体和流体中移动的两种情况是通过正式的伽利略转化链接的，这里的储层定义了连接到半导体结构的特权参考框架，并且两种设置之间的原因显着不同。突出显示了对超流量的临界速度的后果，并将其与共鸣驱动的激子极性子的实验进行了比较。
We theoretically investigate how the presence of a reservoir of incoherent excitations affects the superfluidity properties of resonantly driven polariton fluids. While in the absence of reservoir the two cases of a defect moving in a fluid at rest and of a fluid flowing against a static defect are linked by a formal Galilean transformation, here the reservoir defines a privileged reference frame attached to the semiconductor structure and causes markedly different features between the two settings. The consequences on the critical velocity for superfluidity are highlighted and compared to experiments in resonantly driven excitons polaritons.
