We study black hole evaporation of near-extremal black holes in spherically reduced models with asymptotically Minkowskian spacetime, with the effects of the back-reaction on the geometry included semi-classically. The stress-energy tensor is calculated for null in-falling observers. It is shown that the evaporation proceeds smoothly and there are no instabilities of the outer or inner apparent horizon before the endpoint of evaporation. 

The causal structure of dynamical charged black holes

We study the causal structure of dynamical charged black holes, with a sufficient number of massless fields, using numerical simulations. Neglecting Hawking radiation, the inner horizon is a null

Local Hawking temperature for dynamical black holes

A local Hawking temperature is derived for any future outer trapping horizon in spherical symmetry, using a Hamilton–Jacobi variant of the Parikh–Wilczek tunneling method. It is given by a dynamical

Stress-energy tensor in soluble models of spherically symmetric charged black hole evaporation

We study the decay of a near-extremal black hole in AdS$_2$, related to the near-horizon region of 3+1-dimensional Reissner-Nordstr\"om spacetime, following Fabbri, Navarro, and Navarro-Salas.

Semiclassical decay of near-extremal black holes

The decay of a near-extremal black hole down to the extremal state is studied in the background field approximation to determine the fate of injected matter and Hawking pairs. By examining the

Evaporation of near-extremal Reissner-Nordström black holes.

The formation of near-extremal Reissner-Nordström black holes in the S-wave approximation can be described, near the event horizon, by an effective solvable model. The corresponding one-loop quantum

Numerical simulations of the formation and subsequent evaporation of black holes are performed and the results are found to agree qualitatively with the exactly solved modified CGHS models, namely, that the semiclassical approximation breaks down just before a naked singularity appears.

Semiclassical zero temperature black holes in spherically reduced theories

We numerically integrate the semiclassical equations of motion for spherically symmetric Einstein-Maxwell theory with a dilaton coupled scalar field and look for zero temperature configurations. The

Extremal black holes are studied in a two-dimensional model motivated by a dimensional reduction from four dimensions and a mild singularity is shown to appear at the horizon.

Black hole remnants and the information puzzle.

Pair production of magnetic black holes in a weak magnetic field is estimated in aWeakly coupled semiclassical expansion about an instanton and found to be finite, despite the infinite degeneracy of states, which suggests that these states may store the information apparently lost in black hole scattering processes.
