Superradiant scattering from a hydrodynamic vortex

Slatyer, T.; Savage, Craig

Description

Sound waves scattered from a hydrodynamic vortex may be amplified. Such superradiant scattering follows from the physical analogy between spinning black holes and hydrodynamic vortices, as spinning black holes have an ergoregion within which low frequency waves may be scattered with increased amplitude. While black holes also have an event horizon, a fluid's analogous sonic horizon requires the vortex to have a central drain, which may be challenging to produce experimentally. We show that in...[Show more]
