On the quantum stress tensor for extreme 2D Reissner-Nordstrom black holes

TL;DR

This paper demonstrates that the quantum stress tensor for a massless scalar field remains regular on the horizon of an extreme 2D Reissner-Nordstrom black hole, countering previous claims of divergence.

Contribution

It provides a corrected analysis showing the regularity of the quantum stress tensor on the horizon, challenging prior assertions of divergence.

Findings

Quantum stress tensor is regular on the horizon

Counteracts previous claims of divergence

Supports the stability of extreme 2D Reissner-Nordstrom black holes

Abstract

Contrary to previous claims, it is shown that the expectation values of the quantum stress tensor for a massless scalar field propagating on a two-dimensional extreme Reissner-Nordstrom black hole are indeed regular on the horizon.
