Quasinormal ringing and Unruh-Verlinde temperature of the Frolov Black Hole
In this study, we investigate electromagnetic and Dirac field axial-perturbations of a charged regular black hole arising from quantum gravity effects, commonly referred to as the Frolov black hole, a regular (nonsingular) black hole solution. We derive the master wave equations for massless electromagnetic and Dirac perturbations and solve them using the standard Wentzel-Kramers-Brillouin (WKB) method along with Padé approximation. From these solutions, we extract the dominant and overtone qu…
