Two-Dimensional Self-Consistent Quantum-Corrected Geometries with a Constant Dilaton Feld

TL;DR

This paper discusses how constant dilaton solutions are common in string-inspired dilaton gravity, revealing quantum effects that produce two horizons in black holes, a phenomenon absent in classical physics.

Contribution

It demonstrates that constant dilaton solutions are generic in string-inspired dilaton gravity and explores quantum effects leading to dual horizons in black holes.

Findings

Constant dilaton solutions are generic in string-inspired dilaton gravity.

Quantum effects can create two horizons in black holes in strong coupling regions.

These dual horizons are absent in classical solutions.

Abstract

It is argued that the existence of constant dilaton field solutions is a generic feature of string-inspired dilaton gravity. Such solutins arise in the extreme limit of black hole metrics. It is shown that in a strong coupling region quantum effects give rise to two horizons in thermal equilibrium that has no classical counterpart.
