Resolving the information loss paradox from the five-dimensional minimal supergravity black hole

TL;DR

This paper investigates the Hawking radiation and entropy corrections of five-dimensional minimal supergravity black holes, proposing a condition that may resolve the information loss paradox and analyzing phase transitions influenced by thermal fluctuations.

Contribution

It introduces a novel condition derived from entropy calculations that potentially addresses the black hole information loss paradox in five-dimensional supergravity.

Findings

Corrected entropy calculations lead to a condition that may resolve the paradox.

Thermal fluctuations induce instability and phase transitions in the black hole.

Black holes exhibit behavior similar to those in Horava-Lifshitz gravity, allowing second-order phase transitions.

Abstract

In this paper, we study the Hawking tunneling radiation of the charged rotating black hole in five-dimensional minimal supergravity theory by using the semiclassical Hamilton-Jacobi equation. By using two separated ways we obtain the corrected entropy of the black hole. Equality of results gives us a special condition that may solve the information loss paradox. Then, we focus on the phase transitions, and the results show that if the effects of thermal fluctuations are incorporated in the entropy, the black hole is unstable, while there are phase transitions according to the sign-changing behavior of the black hole specific heat. We find that, in presence of thermal fluctuations, the black holes of five-dimensional minimal supergravity behave like the black holes in Horava-Lifshitz gravity hence the second-order phase transition is possible.
