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…
Analytical approach to critical collapse in 2+1 dimensions
Gerard Clement, Alessandro Fabbri
We present a family of time-dependent solutions to 2+1 gravity with negative cosmological constant and a massless scalar field as source. These solutions are continuously self-simi…
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…
2D black holes and effective actions
R. Balbinot, A. Fabbri
We compare the canonical quantization and the effective action method to derive expectation values of the stress energy tensor for scalar fields conformally coupled to a 2D Schwarz…
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…
Classical stability of black hole Cauchy horizons in two-dimensional asymptotically flat space-times
A. Fabbri
In this paper we analyse the stability of black hole Cauchy horizons arising in a class of 2d dilaton gravity models. It is shown that due to the characteristic asymptotic Rindler…
