Analog black holes and energy extraction by super-radiance from Bose Einstein condensates (BEC) with constant density
This paper investigates the acoustic superradiance of the density and phase fluctuations from the single vortex state of a Bose-Einstein condensate, by employing full time-domain and asymptotic frequency domain numerical calculations. The draining bathtub model of an incompressible barotropic fluid...
