Tunneling of massive and charged particles from noncommutative Reissner-Nordstr\"{o}m black hole

TL;DR

This paper investigates how noncommutative geometry affects particle tunneling from Reissner-Nordstrom black holes, revealing non-thermal radiation and correlations that could address the information loss paradox.

Contribution

It introduces a noncommutative spacetime model to analyze charged particle tunneling, showing deviations from pure thermality and exploring thermodynamic properties.

Findings

Hawking radiation is non-thermal in noncommutative spacetime.

Correlations between emitted particles are present, potentially solving the information loss problem.

Thermodynamics of the noncommutative horizon is analyzed.

Abstract

Massive charged and uncharged particles tunneling from commutative Reissner-Nordstrom black hole horizon has been studied with details in literature. Here, by adopting the coherent state picture of spacetime noncommutativity, we study tunneling of massive and charged particles from a noncommutative inspired Reissner-Nordstrom black hole horizon. We show that Hawking radiation in this case is not purely thermal and there are correlations between emitted modes. These correlations may provide a solution to the information loss problem. We also study thermodynamics of noncommutative horizon in this setup.
