A microscopic description of black hole evaporation via holography

Abstract

We propose a description of how a large, cold black hole (black zero-brane) in type IIA superstring theory evaporates into freely propagating [Formula: see text]0-branes, by solving the dual gauge theory quantitatively. The energy spectrum of emitted [Formula: see text]0-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 [Formula: see text]0-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.
