Reconsidering the black hole final state in Dirac fields

TL;DR

This paper extends the black hole final state proposal to Dirac fields, showing that considering annihilation processes prevents nonlinear evolution and may facilitate information escape from black holes.

Contribution

It introduces a novel extension of the black hole final state concept to Dirac fields and highlights the role of annihilation in information retrieval.

Findings

Annihilation prevents nonlinear evolution in Dirac fields.

Annihilation is central to black hole information escape.

Brief discussion on black hole computation speed.

Abstract

We extend Horowitz and Maldacena's proposal about black hole final state to Dirac fields and find that if annihilation of the infalling positrons and the collapsed electrons inside the horizon is considered, then the nonlinear evolution of collapsing quantum state will be avoided. We further propose that annihilation also plays the central role in the process of black hole information escaping in both Dirac and scalar fields. The computation speed of a black hole is also briefly discussed.
