论文摘要
旋转超高是黑洞物理学中最迷人的现象之一。在这里，为了探测实验室中超高级的量子性能，我们研究了声波与Bose-Einstein冷凝物中量子涡流（BEC）在耗散平均模型框架中的相互作用。我们发现在带环拓扑的冷凝物中，声学诱导的量子相滑的条件，并讨论了观察到超速原子气体中量子超高的声学类似物的可能性。
Rotational superradiance is one of the most fascinating phenomena in black-hole physics. Here, with the aim of probing quantum properties of superradiance in the lab, we investigate the interaction of the acoustic waves with quantum vortices in Bose-Einstein condensates (BEC) in the framework of dissipative mean-field model. We find the conditions of the acoustic-induced quantum phase slips in condensates with ring topology and discuss the possibility of observing an acoustic analogue of quantum superradiance in ultracold atomic gases.
