Quantum-corrected black holes and naked singularities in (2+1)-dimensions

Understand

We analytically investigate the pertubative effects of a quantum conformally-coupled scalar field on rotating (2+1)-dimensional black holes and naked singularities.

• In both cases we obtain the quantum-backreacted metric analytically.
• In the black hole case, we explore the quantum corrections on different regions of relevance for a rotating black hole geometry.
• We find that the quantum effects lead to a growth of both the event horizon and the ergosphere, as well as to a reduction of the angular velocity compared to their corresponding unperturbed values.
