The Entropy of the Rotating Charged Black Threebrane from a Brane-Antibrane System

TL;DR

This paper demonstrates that a finite-temperature D3-brane--anti-D3-brane system model can accurately reproduce the entropy of rotating charged black threebranes, extending previous non-rotating models to include rotation and charge.

Contribution

It extends a brane-antibrane model to successfully describe the entropy of rotating charged black threebranes, including the neutral Kerr case, highlighting a peculiar energy condition.

Findings

Model reproduces entropy of rotating charged black threebranes.

Includes neutral Kerr black hole as a special case.

Suggests a special energy condition on the involved gases.

Abstract

We show that a model based on a D3-brane--anti-D3-brane system at finite temperature, proposed previously as a microscopic description of the non-rotating black threebrane of type IIB supergravity arbitrarily far from extremality, can also successfully reproduce the entropy of the rotating threebrane with arbitrary charge (including the neutral case, which corresponds to the Kerr black hole in seven dimensions). Our results appear to confirm in particular the need for a peculiar condition on the energy of the two gases involved in the model, whose physical interpretation remains to be elucidated.
