Discreteness Unravels the Black Hole Information Puzzle: Insights from a Quantum Gravity Toy Model

Round 1

Reviewer 1 Report

The presence of microscopic degrees of freedom at the Planck scale provides a natural mechanism for resolving the black hole information puzzle. In this paper, the authors aimed to understand the mechanism by which the initially maximally correlated Hawking pairs evolve into a particle escaping to infinity as Hawking radiation correlated to the Planckian degrees of freedom inside. For this, the authors used the simple quantum black hole model inspired by loop quantum gravity to review how microscopic degrees of freedom arise in the infalling scalar quantization, and how quantum correlations between matter excitations and such microscopic degrees of freedom develop unavoidably during dynamical evolution. How correlations are transferred dynamically to the ‘hidden’ quantum hair as the inside excitation approaches the near singularity regime is shown explicitly.

 

The paper is well-written and cover important published literature. The findings presented in this article have significant implications for our understanding of black holes evaporation and information loss paradox. I find the manuscript suitable for publication in the Entropy.

Reviewer 3 Report

  

Minor english editing is required. For example, there is a floating question mark in the text above eq. (2.34). This is not the only misspel within the manuscript and I suggest that the authors read it carefully to edit it correspondingly.
