Tunneling, Page Curve and Black Hole Information

TL;DR

This paper explores how tunneling affects entangled Fermi quanta inside black holes, demonstrating that it reproduces the Page curve and ensures information recovery through Hawking radiation.

Contribution

It introduces a model where tunneling modifies Bell states of Fermi quanta, linking entanglement dynamics to the black hole information paradox.

Findings

Tunneling induces the Page curve in Hawking radiation.

Black hole information is fully recovered via tunneling-affected entanglement.

The model supports unitarity in black hole evaporation.

Abstract

In a recent paper [1], we proposed that the quantum states of black hole responsible for the Bekenstein-Hawking entropy are given by Bell states of Fermi quanta in the interior of black hole. In this paper, we include the effect of tunneling on these entangled states and show that partial tunneling of these Bell states of Fermi quanta give rises to the Page curve of Hawking radiation. We also show that the entirety of information initially stored in the black hole is returned to the outside via the Hawking radiation.
