Tunneling of Bell Particles, Page Curve and Black Hole Information

TL;DR

This paper proposes a model where black hole entropy arises from Bell particles near the horizon, and demonstrates that tunneling of these particles reproduces the Page curve, suggesting information retrieval from black holes.

Contribution

It introduces a novel black hole model with Bell particles stabilized by noncommutative geometry, explaining the Page curve and information recovery via tunneling effects.

Findings

Bell particles account for black hole entropy

Tunneling reproduces the Page curve

Black hole information is recovered through Hawking radiation

Abstract

We propose that the quantum states of black hole responsible for the Bekenstein-Hawking entropy are given by a thin shell of Bell particles located at the region just underneath the horizon. We argue that the configuration can be stabilized by a new kind of degeneracy pressure which is suggested by a noncommutative geometry in the interior of the black hole. Black hole singularity is avoided. We utilize the work of Parikh and Wilczek \cite{Parikh:1999mf} to include the effect of tunneling on the Bell particles. We show that partially tunneled Bell particles give the Page curve of Hawking radiation, and the entirety of information initially stored in the black hole is returned to the outside via the Hawking radiation. In view of entropic force, the location of these Bell states is naturally related to the island and the quantum extremal surface.
