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 ba

We consider two scalar fields interacting through a $$\chi ^*\chi \phi ^*\phi $$ term in the presence of a Reissner–Nordstrom black hole. Initially, only $$\chi $$ particles are present. We find that the produced $$\phi $$ particles are localized i

The propagation of acoustic perturbations in the velocity potential of a Bose-Einstein condensate (BEC) behave like minimally coupled massless scalar fields in a curved (1 + 1) dimensional Lorentzian space-time, where their propagation is governed by
