Scalar particles tunneling radiation in the Demianski-Newman spacetime with influences of quantum gravity

TL;DR

This paper studies how quantum gravity influences scalar particle tunneling in Demianski-Newman spacetime, revealing that quantum effects slow Hawking temperature increase, potentially leaving black hole remnants.

Contribution

It introduces a Hamilton-Jacobi approach to analyze scalar tunneling with quantum gravity effects in a complex spacetime, extending previous fermion studies.

Findings

Quantum gravity slows Hawking temperature rise.

Scalar particles exhibit similar quantum effects as fermions.

Black hole remnants are likely due to temperature stabilization.

Abstract

In this paper,using Hamilton-Jacobi ansatz, we investigate scalar particles tunneling radiation in the Demianski-Newman spacetime. We get the effective temperature with influences of quantum gravity, and compare this temperature with the original temperature of the Demianski-Newman black hole. We find that it's similar to the case of fermions, for scalar particles the influence of quantum gravity will also slow down the increase of Hawking temperatures,which naturally leads to remnants left in the evaporation.
