Abstract
Inspired by Analogue Gravity, superradiance has been previously investigated in Bose-Einstein condensates (BECs). In this work, we revisit this problem by introducing dissipation to the system. After establishing the possibility of quantum vortices in dissipative BECs, we analyze the propagation of elementary excitations, and we demonstrate the existence of superradiant modes, which can be interpreted in terms of the dissipation of ``antiparticles.'' Our findings support the possibility of superradiant scattering around dissipative quantum vortices, and they pave the way for future experimental realization of the phenomenon.
