Black-hole evaporation from the semiclassical Einstein equations in 3+1 dimensions
Adrián del Río, F. Javier Marañón-González
We solve the semiclassical Einstein equations for an evaporating Schwarzschild black hole in closed form, obtaining its backreacted geometry in 3+1 dimensions. This is achieved by…
Singularity resolution and unitarity in two-dimensional dilaton black holes with negative central charge
César García-Pérez, F. Javier Marañón-González, José Navarro-Salas +1
We study a one-loop corrected extension of the classical Callan-Giddings-Harvey-Strominger (CGHS) model of two-dimensional dilaton gravity. The effective action combines the non-lo…
Singularity resolution in the backreacted Schwarzschild geometry from 2D matter with negative central charge
F. J. Marañón-González, A. del Río, J. Navarro-Salas
Two-dimensional dilaton gravity provides a valuable framework to study the dynamics of quantum black holes. These models are often coupled to conformal scalar fields, which capture…
Adiabatic regularization for massive and massless spin- fields
F. Javier Marañón-González, José Navarro-Salas
The adiabatic regularization method is likely the most direct and intuitive renormalization scheme for FLRW cosmologies. The method requires one to start with a nonvanishing mass,…
Singularity resolution in spherically reduced 2D semiclassical gravity with negative central charge
Adrián del Río, F. Javier Marañón-González, José Navarro-Salas
We analyze the semiclassical Schwarzschild geometry in the Boulware quantum state in the framework of two-dimensional (2D) dilaton gravity. The classical model is defined by the sp…
Adiabatic regularization for spin- fields
F. Javier Marañón-González, José Navarro-Salas
We analyze the adiabatic regularization scheme to renormalize Proca fields in a four-dimensional Friedmann-Lemaître-Robertson-Walker spacetime. The adiabatic method is well establi…
