Nonviolent information transfer from black holes: a field theory parameterization

TL;DR

This paper proposes an effective field theory parameterization for quantum information transfer from black holes, suggesting it can occur without violent effects and may increase energy flux, thus addressing unitarity restoration.

Contribution

It introduces a novel effective field theory framework for black hole information transfer that allows for nonviolent transfer mechanisms compatible with unitarity.

Findings

Infalling observers do not experience violence due to information transfer.

Moderate-frequency couplings can enhance information transfer rates.

Models predict additional energy flux beyond Hawking radiation.

Abstract

A candidate parameterization is introduced, in an effective field theory framework, for the quantum information transfer from a black hole that is necessary to restore unitarity. This in particular allows description of the effects of this information transfer in the black hole atmosphere, for example seen by infalling observers. In the presence of such information transfer, it is shown that infalling observers need not experience untoward violence. Moreover, the presence of general moderate-frequency couplings to field modes with high angular momenta offers a mechanism to enhance information transfer rates, commensurate with the increased energy flux, when a string is introduced to "mine" a black hole. Generic such models for nonviolent information transfer predict extra energy flux from a black hole, beyond that of Hawking.
