Symmetries and solvable models for evaporating 2D black holes
J. Cruz, J. Navarro-Salas, M. Navarro, C. F. Talavera
Abstract
We study the evaporation process of a 2D black hole in thermal equilibrium when the ingoing radiation is switched off suddenly. We also introduce global symmetries of generic 2D dilaton gravity models which generalize the extra symmetry of the CGHS model.
