Quantum corrections for an (anti) evaporating black hole

Abstract

In this paper we analyze the quantum correction for a Schwarzschild black hole in the Unruh state in the framework of the spherically symmetric gravity (SSG) model. SSG is a two-dimensional dilaton model that is obtained by spherically symmetric reduction from four-dimensional theory. We find the one-loop geometry of the (anti)evaporating black hole and corrections for mass, entropy, and apparent horizon. ©2001 The American Physical Society.
