Abstract

Quantum gravity corrections to the probability of emission of a particle from a black hole in the Parikh–Wilczek tunneling framework are studied. We consider the effects of zero-point quantum fluctuations of the metric on the emission probability for a tunneling shell. Quantum properties of the geometry are responsible for the formation of a “quantum ergosphere” whose effects on the emission probability can be related to the emergence of a logarithmic correction to the Bekenstein–Hawking entropy–area formula.
