# Near-extremal black hole evaporation in asymptotically flat spacetime

@article{Diba2002NearextremalBH, title={Near-extremal black hole evaporation in asymptotically flat spacetime}, author={Kamran Diba and David A. Lowe}, journal={Physical Review D}, year={2002}, volume={66}, pages={024039} }

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.

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.

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.
