Bubbling solutions, entropy enhancement and the fuzzball proposal

TL;DR

This paper discusses bubbling solutions as microstates of black holes and how supertubes in these backgrounds can have their entropy significantly increased, potentially explaining the black hole entropy.

Contribution

It introduces a family of bubbling solutions and demonstrates entropy enhancement of supertubes within these backgrounds, advancing the fuzzball proposal.

Findings

Bubbling solutions serve as microstates for black holes.

Supertubes exhibit entropy enhancement in these backgrounds.

Potential explanation for the entropy of three-charge black holes.

Abstract

In this short note we explain the main idea of the work done in arXiv:0804.4487[hep-th] and arXiv:0812.2942[hep-th]. We present a family of black hole microstates, the bubbling solutions. We then explain how supertubes placed in such backgrounds have their entropy enhanced by the presence of the background dipole charges. This indicates this could account for a large amount in the entropy of the three charge black hole.
