Symmetries and solvable models for evaporating 2D black holes
J. Cruz, J. Navarro-Salas, M. Navarro +1
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 di…
New Symmetries in Two-Dimensional Dilaton Gravity
J. Cruz, J. Navarro-Salas, M. Navarro +1
We present three types of non-conformal symmetries for a wide class of 2D dilaton-gravity models. For the particular CGHS, or string-inspired model, a linear combination of these s…
Conformal and Nonconformal Symmetries in 2d Dilaton gravity
J. Cruz, J. Navarro-Salas, M. Navarro +1
We study finite-dimensional extra symmetries of generic 2D dilaton gravity models. Using a non-linear sigma model formulation we show that the unique theories admitting an extra (c…
Weyl Invariance and Black Hole Evaporation
J. Navarro-Salas, M. Navarro, C. F. Talavera
We consider the semiclassical dynamics of CGHS black holes with a Weyl-invariant effective action for conformal matter. The trace anomaly of Polyakov effective action is converted…
Diffeomorphisms, Noether Charges and Canonical Formalism in 2D Dilaton Gravity
J. Navarro-Salas, M. Navarro, C. F. Talavera
We carry out a parallel study of the covariant phase space and the conservation laws of local symmetries in two-dimensional dilaton gravity. Our analysis is based on the fact that…
On The Reduced Canonical Quantization Of The Induced 2D-Gravity
J. Navarro-Salas, M. Navarro, C. F. Talavera +1
The quantization of the induced 2d-gravity on a compact spatial section is carried out in three different ways. In the three approaches the supermomentum constraint is solved at th…
