Late-time correlators in semiclassical particle-black hole scattering
A. Fabbri, D. J. Navarro, J. Navarro-Salas +1
We analyse the quantum corrected geometry and radiation in the scattering of extremal black holes by low-energy neutral matter. We point out the fact that the correlators of local…
Low-energy scattering of extremal black holes by neutral matter
A. Fabbri, D. J. Navarro, J. Navarro-Salas
We investigate the decay of a spherically symmetric near-extremal charged black hole, including back-reaction effects, in the near-horizon region. The non-locality of the effective…
A Planck-like problem for quantum charged black holes
A. Fabbri, D. J. Navarro, J. Navarro-Salas
Motivated by the parallelism existing between the puzzles of classical physics at the beginning of the XXth century and the current paradoxes in the search of a quantum theory of g…
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…
Quantum evolution of near-extremal Reissner-Nordstrom black holes
A. Fabbri, D. J. Navarro, J. Navarro-Salas
We study the near-horizon AdS_2\timesS^2 geometry of evaporating near-extremal Reissner-Nordstrom black holes interacting with null matter. The non-local (boundary) terms t_{\pm},…
Evaporation of near-extremal Reissner-Nordstrom black holes
Alessandro Fabbri, Diego J. Navarro, Jose Navarro-Salas
The formation of near-extremal Reissner-Nordstrom black holes in the S-wave approximation can be described, near the event horizon, by an effective solvable model. The correspondin…
Integrable models, degenerate horizons and AdS_2 black holes
J. Cruz, A. Fabbri, D. J. Navarro +2
The near extremal Reissner-Nordstrom black holes in arbitrary dimensions ca be modeled by the Jackiw-Teitelboim (JT) theory. The asymptotic Virasoro symmetry of the corresponding J…
Holography, degenerate horizons and entropy
Diego J. Navarro, Jose Navarro-Salas, Pedro Navarro
We show that a realization of the correspondence AdS_2/CFT_1 for near extremal Reissner-Nordstrom black holes in arbitrary dimensional Einstein-Maxwell gravity exactly reproduces,…
Integrable models and degenerate horizons in two-dimensional gravity
J. Cruz, A. Fabbri, D. J. Navarro +1
We analyse an integrable model of two-dimensional gravity which can be reduced to a pair of Liouville fields in conformal gauge. Its general solution represents a pair of ``mirror'…
Bäcklund transformations in 2D dilaton gravity
D. J. Navarro, J. Navarro-Salas
We give a Bäcklund transformation connecting a generic 2D dilaton gravity theory to a generally covariant free field theory. This transformation provides an explicit canonical tran…
General Covariance and Free Fields in Two Dimensions
J. Cruz, D. J. Navarro, J. Navarro-Salas
We investigate the canonical equivalence of a matter-coupled 2D dilaton gravity theory defined by the action functional $S = \int d^2x \sqrt{-g} (Rϕ+ V(ϕ) - 1/2 H(ϕ) (\nablaf)^2)$,…
Free fields via canonical transformations of matter-coupled 2D dilaton gravity models
J. Cruz, J. M. Izquierdo, D. J. Navarro +1
It is shown that the 1+1-dimensional matter-coupled Jackiw-Teitelboim model and the model with an exponential potential can be converted by means of appropriate canonical transform…
A (1+3) Relativistic Harmonic Oscillator Simulated by an Anti-de Sitter Background
D. J. Navarro, J. Navarro-Salas
It is shown that a static anti-de Sitter metric defines, in a natural way, a relativistic harmonic oscillator in Minkowski space. The quantum theory can be solved exactly a…
