Superradiance in acoustic black hole [PDF]
arXivRotating superradiance in cylinders has recently been observed experimentally using acoustic waves to shed light on the understanding of the superradiant phenomenon in black holes. In this paper, for the first time, we study superradiance in acoustic black holes through theoretical analysis and numerical simulation using COMSOL multiphysics.
