4D and 2D Evaporating Dilatonic Black Holes
The picture of S-wave scattering from a 4D extremal dilatonic black hole is examined. Classically, a small matter shock wave will form a non-extremal black hole. In the “throat region” the r − t geometry is exactly that of a collapsing 2D black hole. The 4D Hawking radiation (in this classical background) gives the 2D Hawking radiation exactly in the throat region. Inclusion of the back-reactio...
متن کاملTwo-Dimensional Dilatonic Black Holes and Hawking Radiation
Hawking radiation emanating from two-dimensional charged and uncharged dilatonic black holes dimensionally reduced from (2 + 1) spinning and spinless, respectively, BTZ black holes is viewed as a tunnelling process. Two dimensional dilatonic black holes (AdS(2) included) are treated as dynamical backgrounds in contrast to the standard methodology where the background geometry is fixed when eval...
متن کامل2 Higher dimensional black holes and supersymmetry
It has recently been shown that the uniqueness theorem for stationary black holes cannot be extended to five dimensions. However, uniqueness is an important assumption of the string theory black hole entropy calculations. This paper justifies this assumption by proving a uniqueness theorem for supersymmetric black holes in five dimensions. Some remarks concerning general properties of non-super...
متن کاملEvaporating black holes and entropy.
We study the Hawking radiation for the geometry of an evaporating 1+1 dimensional black hole. We compute Bogoliubov coefficients and the stress tensor. We use a recent result of Srednicki to estimate the entropy of entanglement produced in the evaporation process, for the 1+1 dimensional hole and for the 3+1 dimensional hole. It is found that the one space dimensional result of Srednicki is the...
متن کاملClassical and quantum aspects of 4 dimensional black holes ∗
In this talk I address some aspects in the recent developments for N = 2 black holes in 4 dimensions. I restrict myself on axion-free solutions that can classically be related to intersections of isotropic Dor M -branes. After reviewing of some classical properties I include corrections coming from a general cubic prepotential. On the heterotic side these are quantum corrections for these black...
