Coherent electrically-charged quantum black holes

TL;DR

This paper develops a quantum-corrected Reissner-Nordström black hole model that resolves singularities and analyzes its physical properties, including geodesics and quasinormal modes, to enhance understanding of quantum effects in charged black holes.

Contribution

It introduces an improved quantum-corrected black hole geometry with an integrable singularity and no spurious oscillations, extending previous models and analyzing related physical observables.

Findings

The geometry has an integrable singularity at the center.

No spurious oscillations are present around the classical configuration.

Physical observables like geodesics and quasinormal modes are characterized.

Abstract

We improve upon the results presented in [R. Casadio, et al., Phys. Rev. D 105 (2022) 124026] deriving a quantum-corrected Reissner-Nordstr\"om geometry containing an integrable singularity at its center while being devoid of spurious oscillations around the classical configuration. We further investigate some relevant physical observables, related to geodesics and quasinormal modes of scalar perturbations, associated with this geometry to complement our theoretical analysis.
