Information paradox and corrected thermodynamics for black holes

TL;DR

This paper investigates quantum corrections to black hole entropy and temperature, compares entropy variations, and discusses implications for the black hole information paradox.

Contribution

It introduces quantum-corrected entropy and temperature calculations for black holes and analyzes their impact on the information paradox.

Findings

Corrected entropy variation exceeds uncorrected variation.

The ratio of entropy variations increases with quantum corrections.

Implications for resolving the black hole information paradox.

Abstract

We generally consider that entropy and temperature of a spherically symmetric black hole are corrected by quantum effect. We calculate interior entropy variation of massless scalar field and compare it with corrected Bekenstein-Hawking entropy variation for the evaporating black hole. We find that the corrected ratio between them is greater than the uncorrected one. The information paradox is then discussed.
