The Stress-Energy Tensor in Soluble Models of Spherically Symmetric Charged Black Hole Evaporation

arXiv:hep-th/0107137 · doi:10.1103/PhysRevD.65.024018

Abstract

We study the decay of a near-extremal black hole in AdS, related to the near-horizon region of 3+1-dimensional Reissner-Nordström spacetime, following Fabbri, Navarro, and Navarro-Salas. Back-reaction is included in a semiclassical approximation. Calculations of the stress-energy tensor of matter coupled to the physical spacetime for an affine null observer demonstrate that the black hole evaporation proceeds smoothly and the near-extremal black hole evolves back to an extremal ground state, until this approximation breaks down.
