Analytic study of superradiant stability of Kerr–Newman black holes under charged massive scalar perturbation
Abstract The superradiant stability of a Kerr–Newman black hole and charged massive scalar perturbation is investigated. We treat the black hole as a background geometry and study the equation of motion of the scalar perturbation. From the radial equation of motion, we derive the effective potential...
