Entropy bound for a charged object from the Kerr-Newman black hole

TL;DR

This paper derives an upper entropy bound for a charged object using thermodynamics of a Kerr-Newman black hole linearized with respect to its electric charge.

Contribution

It provides a new derivation of the entropy bound specifically for charged objects based on Kerr-Newman black hole thermodynamics.

Findings

Established an entropy bound for charged objects.

Utilized linearized thermodynamics of Kerr-Newman black holes.

Reinforced the theoretical understanding of entropy limits in charged systems.

Abstract

We derive again the upper entropy bound for a charged object by employing thermodynamics of the Kerr-Newman black hole linearised with respect to its electric charge
