Diagonalizing the Black Hole Information Retrieval Process

TL;DR

This paper proposes a diagonalized formalism based on classical gravitational back-reaction to better understand how black holes release absorbed information, suggesting a string-like interaction without relying on string theory.

Contribution

Abstract

The mechanism by which black holes return the absorbed information to the outside world is reconsidered, and described in terms of a set of mutually non-interacting modes. Our mechanism is based on the mostly classical gravitational back-reaction. The diagonalized formalism is particularly useful for further studies of this process. Although no use is made of string theory, our analysis appears to point towards an ensuing string-like interaction. It is shown how black hole entropy can be traced down to classical gravitational back-reaction.
