Breakdown of Field Theory in Near-Horizon Regions

Abstract

We discuss back-reaction in the semiclassical treatment of quantum fields near a black hole. When the state deviates significantly from Hartle-Hawking, simple energetic considerations of back-reaction give rise to a characteristic radial distance scale (rs2GN)1/D\sim (r_s^{2}G_N)^{1/D}, below which some breakdown of effective field theory may occur.
