A Planck-like problem for quantum charged black holes

TL;DR

This paper provides an exact solution for Hawking radiation from charged black holes, demonstrating that including back-reaction effects significantly changes the evaporation process and may help resolve the information loss paradox.

Contribution

It introduces a novel approach analogous to Planck's black body radiation problem to solve for Hawking flux, incorporating back-reaction effects for charged black holes.

Findings

Back-reaction effects alter the standard black hole evaporation picture.

The exact Hawking flux for Reissner-Nordstrom black holes is derived.

Potential implications for resolving the information loss problem.

Abstract

Motivated by the parallelism existing between the puzzles of classical physics at the beginning of the XXth century and the current paradoxes in the search of a quantum theory of gravity, we give, in analogy with Planck's black body radiation problem, a solution for the exact Hawking flux of evaporating Reissner-Nordstrom black holes. Our results show that when back-reaction effects are fully taken into account the standard picture of black hole evaporation is significantly altered, thus implying a possible resolution of the information loss problem.
