论文摘要
在最近的实验中，我们从理论上分析了一维“光量子流体”的障碍物，该流程是互助驱动的，并具有双重性。当流体速度或障碍势强度增加时，发现流动突然改变了几次。与通常的液体和超流体的情况相反，过渡发生在固定状态之间。它们以必不可少的方式涉及流体的双重性。值得注意的是，在过渡点，障碍物唤醒中的流体在于中间密度状态不稳定。
Motivated by recent experiments, we theoretically analyze the flow past an obstacle of a one-dimensional "quantum fluid of light" which is resonantly driven, and exhibits bistability. The flow is found to abruptly change several times when the fluid velocity or the obstacle potential strength are increased. In contrast to the cases of usual fluids and superfluids, the transitions take place between stationary states. They involve the fluid bistability in an essential way. Remarkably, at the transitions points, the fluid in the obstacle wake lies in the unstable intermediate density state.
