Hawking radiation as a manifestation of spontaneous symmetry breaking

TL;DR

This paper models black hole evaporation as spontaneous symmetry breaking, revealing how particle types are determined and explaining the universality of the process through modifications of gravity.

Contribution

It introduces a novel framework linking black hole evaporation to spontaneous symmetry breaking, with parameters controlling particle types and universality.

Findings

Particle emission type depends on free-parameter sign.

Black hole evaporation universality explained by symmetry breaking.

Modifications of gravity naturally produce the observed universality.

Abstract

We demonstrate that the black hole evaporation can be modelled as a process where one symmetry of the system is spontaneously broken continuously. We then identify three free-parameters of the system. The sign of one of the free-parameters, governs whether the particles emitted by the black-hole are fermions or bosons. The present model explains why the Black Hole evaporation process is so universal. Interestingly, this universality emerges naturally inside certain modifications of gravity.
