Entropy Conservation of Linear Dilaton Black Holes in Quantum Corrected Hawking Radiation

TL;DR

This paper demonstrates that considering quantum corrections and black hole remnants in linear dilaton black holes ensures entropy conservation and unitarity, indicating information can escape during Hawking radiation.

Contribution

It introduces quantum gravity corrections and remnant modeling to show entropy conservation and information leakage in linear dilaton black holes.

Findings

Quantum corrections restore entropy conservation.

Black hole remnants have zero temperature and do not radiate.

Information can leak out, preserving unitarity.

Abstract

It has been shown recently that information is lost in the Hawking radiation of the linear dilaton black holes in various theories when applying the tunneling formulism without considering quantum gravity effects. In this Letter, we recalculate the emission probability by taking into account of the log-area correction to the Bekenstein-Hawking entropy and the statistical correlation between quanta emitted. The crucial role of the black hole remnant on the entropy conservation is highlighted. We model the remnant as a higher dimensional linear dilaton vacuum in order to show that such a remnant model cannot radiate and its temperature would be zero. In addition to this, the entropy conservation in the higher dimensional linear dilaton black holes is also discussed. In summary, we show in detail that the information can also leak out from the linear dilaton black holes together with preserving unitarity in quantum mechanics.
