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…
Emergent gauge symmetries: Yang-Mills theory
Carlos Barceló, Raúl Carballo-Rubio, Luis J. Garay +1
Gauge symmetries remove unphysical states and guarantee that field theories are free from the pathologies associated with these states. In this work we find a set of general condit…
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…
