Abstract

The black-hole evaporation implies that the quantum-field propagators in a local Minkowski frame acquire a correction, which gives rise to this process. The modification of the propagators causes, in turn, non-trivial local effects due to the radiative/loop diagrams in non-linear QFTs. In particular, there should be imprints of the evaporation in QED, if one goes beyond the tree-level approximation. Of special interest in this respect is the region near the black-hole horizon, which, already at tree level, appears to show highly non-classical features, e.g., negative energy density and energy flux into the black hole.

Summary

Introduction

After many years of theoretical and experimental studies, we have been successful in establishing a couple of models, which incredibly well describe physics at microscopic and macroscopic scales. Minkowski spacetime appears to be a good approximation to the Universe locally, i.e. in the neighbourhood of any given space-time point. The geometrical structure relevant for Particle Physics is given by the Minkowski metric of a local Minkowski frame.
