Collapse of the wavefunction, the information paradox and backreaction

TL;DR

This paper investigates the black hole information paradox using collapse theories and backreaction effects within a two-dimensional evaporation model, proposing modifications to semiclassical Einstein equations.

Contribution

It introduces a framework combining collapse theories with backreaction in a 2D black hole model, advancing understanding of information loss.

Findings

Collapse theories can be integrated with backreaction effects.

Modifications to semiclassical equations are necessary in collapse scenarios.

The approach offers new insights into the information paradox.

Abstract

We consider the black hole information problem within the context of collapse theories in a scheme that allows the incorporation of the backreaction to the Hawking radiation. We explore the issue in a setting of the two dimensional version of black hole evaporation known as the Russo-Susskind-Thorlacius model. We summarize the general ideas based on the semiclassical version of Einstein's equations and then discuss specific modifications that are required in the context of collapse theories when applied to this model.
