TL;DR

This paper offers a detailed holographic model of black hole evaporation in string theory, showing how a large black hole emits D0-branes and completely evaporates without remnants, aligning with quantum gravity principles.

Contribution

It provides a quantitative gauge theory description of black hole evaporation, demonstrating the process without information loss in a string theory context.

Findings

Black hole emits D0-branes with near-thermal energy spectrum

Black hole becomes hotter and stringier as it evaporates

Complete evaporation occurs without leaving remnants

Abstract

We propose a description of how a large, cold black hole (black zero-brane) in type IIA superstring theory evaporates into freely propagating D0-branes, by solving the dual gauge theory quantitatively. The energy spectrum of emitted D0-branes is parametrically close to thermal when the black hole is large. The black hole, while initially cold, gradually becomes an extremely hot and stringy object as it evaporates. As it emits D0-branes, its emission rate speeds up and it evaporates completely without leaving any remnant. Hence this system provides us with a concrete holographic description of black hole evaporation without information loss.
