Two-dimensional black holes in accelerated frames: quantum aspects

TL;DR

This paper explores quantum properties of two-dimensional black holes in accelerated frames, revealing stable gravitational kinks with unique mass-charge relations and non-zero horizon surface gravity, differing from classical solutions.

Contribution

It introduces quantum mechanically stable gravitational kinks in 2D dilaton gravity with a simple mass-charge relation and non-zero horizon surface gravity, contrasting with classical Einsteinian black holes.

Findings

Existence of quantum stable gravitational kinks.

Unique mass to charge relation for these kinks.

Nonvanishing horizon surface gravity distinguishes them from classical solutions.

Abstract

By considering charged black hole solutions of a one parameter family of two dimensional dilaton gravity theories, one finds the existence of quantum mechanically stable gravitational kinks with a simple mass to charge relation. Unlike their Einsteinian counterpart (i.e. extreme Reissner-Nordstr\"om), these have nonvanishing horizon surface gravity.
