Quantum electromagnetic phenomena far from small evaporating black holes

TL;DR

This paper explores how small, primordial evaporating black holes can leave detectable local imprints in quantum electrodynamics, revealing subtle effects of black holes on quantum vacuum fluctuations.

Contribution

It introduces the concept of black hole imprints in quantum processes far from the black holes, extending understanding of quantum field behavior in weak gravity regimes.

Findings

Black holes can produce observable effects in quantum electrodynamics.

Vacuum fluctuations can carry signatures of black hole presence.

Local imprints of black holes may be detectable in quantum experiments.

Abstract

One might expect far away from physical black holes that quantum field quantisation performed in Minkowski space is a good approximation. Indeed, all experimental tests in particle colliders reveal no deviations so far. Nevertheless, the black holes should leave certain imprints of their presence in quantum processes. In this paper, we shall discuss several local imprints of small, primordial evaporating black holes in quantum electrodynamics in the weak gravity regime. Physically this can be interpreted as being macroscopic manifestations of vacuum fluctuations.
