Quasi-normal Modes of Electromagnetic Perturbations of Four-Dimensional Topological Black Holes with Scalar Hair
TLDR
In this paper, the perturbative behavior of topological black holes with scalar hair was studied and the quasi-normal modes of the electromagnetic perturbations were calculated analytically and numerically.Abstract:
We study the perturbative behaviour of topological black holes with scalar hair. We calculate both analytically and numerically the quasi-normal modes of the electromagnetic perturbations. In the case of small black holes we find evidence of a second-order phase transition of a topological black hole to a hairy configuration.read more
