Generalized Virasoro anomaly for dilaton coupled theories
A. Fabbri, S. Farese, J. Navarro-Salas
We derive the anomalous transformation law of the quantum stress tensor for a 2D massless scalar field coupled to an external dilaton. This provides a generalization of the Virasor…
Evaporation of charged black holes near extremality
A. Fabbri, D. J. Navarro, J. Navarro-Salas
The AdS_2\timesS^2 geometry of near-extremal Reissner-Nordstrom black holes can be described by an effective solvable model which allows to follow analytically the evaporation proc…
Exact late time Hawking radiation and the information loss problem for evaporating near-extremal black holes
Alessandro Fabbri, Diego J. Navarro, Jose Navarro-Salas
In this paper we investigate the effects of gravitational backreaction for the late time Hawking radiation of evaporating near-extremal black holes. This problem can be studied wit…
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…
