论文摘要
模拟重力能够研究实验室弯曲的空间。在事件范围内或登山处的扩增有许多实验平台。在这里，我们证明了如何在极化微腔中的光学产生缺陷，从而可以创建一维和二维的跨音符流动。我们表明，这种高度可调的方法允许创建声音视野。此外，我们提出类似于水波浴缸涡流的旋转几何形状。这些实验使观察到光流体中观察到刺激和自发放大的可能性。
Analogue gravity enables the study of fields on curved spacetimes in the laboratory. There are numerous experimental platforms in which amplification at the event horizon or the ergoregion has been observed. Here, we demonstrate how optically generating a defect in a polariton microcavity enables the creation of one- and two-dimensional, transsonic fluid flows. We show that this highly tuneable method permits the creation of sonic horizons. Furthermore, we present a rotating geometry akin to the water-wave bathtub vortex. These experiments usher-in the possibility of observing stimulated as well as spontaneous amplification by the Hawking, Penrose and Zeld'ovich effects in fluids of light.
