Aligned electromagnetic excitations of a black hole and their impact on its quantum horizon

TL;DR

This paper investigates how aligned electromagnetic excitations, modeled as light-like beams, significantly alter black hole horizons by creating micro holes, linking quantum vacuum fluctuations with horizon topology changes.

Contribution

It demonstrates that electromagnetic beam-like excitations cause topological deformations of black hole horizons, revealing a connection between vacuum fluctuations and horizon microstructure.

Findings

Electromagnetic beams pierce the horizon, forming micro holes.

Horizon deformations are linked to vacuum fluctuations.

Excitations relate to Kerr geometry's conformal-analytic properties.

Abstract

We show that elementary aligned electromagnetic excitations of black holes, as coming from exact Kerr-Schild solutions, represent light-like beam pulses which have a very strong back reaction on the metric and change the topology of the horizon. Based on York's proposal, that elementary deformations of the BH horizon are related with elementary vacuum fluctuations, we analyze deformation of the horizon caused by the beam-like vacuum fluctuations and obtain a very specific feature of the topological deformations of the horizon. In particular, we show how the beams pierce the horizon, forming a multitude of micro holes in it. A conjecture is taken into consideration, that these specific excitations are connected with the conformal-analytic properties of the Kerr geometry and are at the base of the emission mechanism.
