A String Model of Black Hole Microstates

TL;DR

This paper models black hole microstates using a string gas framework, offering insights into black hole thermodynamics and suggesting potential fundamental string theory simplifications beyond supersymmetry.

Contribution

It introduces a string-based model for black hole microstates that passes various consistency checks and predicts new non-perturbative string theory features.

Findings

Model reproduces black hole thermodynamics

Provides non-trivial consistency checks

Suggests simplifications in non-perturbative string theory

Abstract

The statistical mechanics of black holes arbitrarily far from extremality is modeled by a gas of weakly interacting strings. As an effective low energy description of black holes the model provides a number of highly non-trivial consistency checks and predictions. Speculations on a fundamental origin of the model suggest surprising simplifications in non-perturbative string theory, even in the absence of supersymmetry.
