Surprises in the Evaporation of 2-Dimensional Black Holes | | Abhay Ashtekar

30 Nov 2010 | | Abstract: | Quantum evaporation of Callen-Giddings-Harvey-Strominger (CGHS) black holes
is analyzed in the mean field approximation. The resulting semi-classical
theory incorporates back reaction. Detailed analytical and numerical
calculations show that, while some of the assumptions underlying the standard
evaporation paradigm are borne out, several are not. Furthermore, if the black
hole is initially macroscopic, the evaporation process exhibits remarkable
universal properties. Although the literature on CGHS black holes is quite
rich, these features had escaped previous analyses, in part because of lack of
required numerical precision, and in part because certain properties and
symmetries of the model were not recognized. Finally, our results provide
support for the full quantum scenario recently developed by Ashtekar, Taveras
and Varadarajan. | | Source: | arXiv, 1011.6442 | | Services: | Forum | Review | PDF | Favorites | |
