Statistical mechanics of Kerr-Newman dilaton black holes and the bootstrap condition

TL;DR

This paper investigates the statistical mechanics of Kerr-Newman dilaton black holes, computing their entropy perturbatively and analyzing their most probable configurations, suggesting black holes as excitations of extended objects.

Contribution

It introduces a perturbative calculation of black hole entropy and proposes a bootstrap condition, offering new insights into black hole microstates and their physical interpretation.

Findings

Entropy computed in a charge-to-mass ratio expansion

Most probable configuration does not satisfy equipartition

Supports black holes as excitations of extended objects

Abstract

The Bekenstein-Hawking ``entropy'' of a Kerr-Newman dilaton black hole is computed in a perturbative expansion in the charge-to-mass ratio. The most probable configuration for a gas of such black holes is analyzed in the microcanonical formalism and it is argued that it does not satisfy the equipartition principle but a bootstrap condition. It is also suggested that the present results are further support for an interpretation of black holes as excitations of extended objects.
