Maximal Acceleration Effects in Reissner-Nordstrom Space

TL;DR

This paper investigates how maximal acceleration influences particle dynamics near Reissner-Nordstrom black holes, revealing potential barriers that prevent black hole formation and minimal effects on naked singularities.

Contribution

It introduces a model incorporating maximal acceleration into Reissner-Nordstrom spacetime, showing significant effects on black hole formation processes.

Findings

Repulsive potential barriers form near the horizon

Black hole formation via accretion is hindered

Naked singularities are largely unaffected

Abstract

The dynamics of a relativistic particle in a Reissner-Nordstrom background is studied using Caianiello model with maximal acceleration. The behaviour of the particle, embedded in a new effective geometry, changes with respect to the classical scenario because of the formation of repulsive potential barriers near the horizon. Black hole formation by accretion of massive particles is not therefore a viable process in the model. At the same time, the naked singularity remains largely unaffected by maximal acceleration corrections.
