Statistical Entropy of Near Extremal Five-branes

TL;DR

This paper calculates the entropy of near extremal five-branes using string theory, linking it to black hole entropy in five dimensions, and providing insights into the microscopic origin of black hole thermodynamics.

Contribution

It introduces a method to compute the entropy of near extremal five-branes via string gas models, connecting string theory with black hole entropy.

Findings

Entropy matches the Bekenstein-Hawking formula

String gas model reproduces black hole thermodynamics

Provides a microscopic explanation for black hole entropy

Abstract

The Hawking Beckenstein entropy of near extremal fivebranes is calculated in terms of a gas of strings living on the fivebrane. These fivebranes can also be viewed as near extremal black holes in five dimensions.
