Semiclassical constant-density spheres in a regularized Polyakov approximation
Julio Arrechea, Carlos Barceló, Raúl Carballo-Rubio +1
We provide an exhaustive analysis of the complete set of solutions of the equations of stellar equilibrium under semiclassical effects. As classical matter we use a perfect fluid o…
Reissner-Nordström geometry counterpart in semiclassical gravity
Julio Arrechea, Carlos Barceló, Raúl Carballo-Rubio +1
We compute the Renormalized Stress-Energy Tensor (RSET) of a massless minimally coupled scalar field in the Regularized Polyakov approximation, as well as its backreaction, on the…
Inversion of statistics and thermalization in the Unruh effect
Julio Arrechea, Carlos Barceló, Luis J. Garay +1
We derive a master equation for the reduced density matrix of a uniformly accelerating quantum detector in arbitrary dimensions, generically coupled to a field initially in its vac…
Black hole inner horizon evaporation in semiclassical gravity
Carlos Barceló, Valentin Boyanov, Raúl Carballo-Rubio +1
In this work we analyse the backreaction of a quantum field on a spherically symmetric black hole geometry with an inner horizon, i.e. an internal boundary of the trapped region. W…
Interpretations and naturalness in the radiation-reaction problem
Carlos Barceló, Luis J. Garay, Jaime Redondo-Yuste
After more than a century of history, the radiation-reaction problem in classical electrodynamics still surprises and puzzles new generations of researchers. Here we revise and exp…
Asymptotic horizon formation, spacetime stretching and causality
Carlos Barceló, Valentin Boyanov, Raúl Carballo-Rubio +1
In this work we analyse asymptotically flat, spherically symmetric spacetimes in which an event horizon is present without any trapped surfaces. We identify two types of such space…
