Entropy of Non-Extreme Rotating Black Holes in String Theories

TL;DR

This paper develops a Rindler space framework for rotating black holes in string theories, simplifying thermodynamic analysis and calculating their statistical entropies, which qualitatively agree with classical Bekenstein-Hawking entropies.

Contribution

It introduces a Rindler space approach for rotating black holes and computes their statistical entropies in heterotic string theory, providing new insights into black hole thermodynamics.

Findings

Qualitative agreement between Bekenstein-Hawking and statistical entropies

Simplified thermodynamic analysis in the comoving frame

Application of D-brane description to rotating black holes

Abstract

We formulate the Rindler space description of rotating black holes in string theories. We argue that the comoving frame is the natural frame for studying thermodynamics of rotating black holes and statistical analysis of rotating black holes gets simplified in this frame. We also calculate statistical entropies of general class of rotating black holes in heterotic strings on tori by applying D-brane description and the correspondence principle. We find at least qualitative agreement between the Bekenstein-Hawking entropies and the statistical entropies of these black hole solutions.
