Logarithmic corrections to black hole entropy from minimum-assumptions discretization
Pelayo V. Calzada, Ana Alonso-Serrano, Ernesto Contreras +1
We introduce here a general model, under agnostic and minimum assumptions, to uniquely find the entropy area law with a corresponding fixed logarithmic correction term. In this app…
Evading Cauchy horizon excision in scalarized regular black holes
Ernesto Contreras, Pedro Bargueño, Arthur G. Suvorov
Spontaneous scalarization provides a dynamical mechanism to evade the no-hair paradigm, but it has been argued to generically eliminate the Cauchy horizon in charged black holes. W…
Homogeneous and Isotropic Linearized Gravity as a Caldeira--Leggett System
Pelayo V. Calzada, Pedro Bargueño
We show that the homogeneous and isotropic sector of linearized gravity coupled to arbitrary additional degrees of freedom takes the Caldeira-Leggett form, provided their action co…
Penrose-Rindler equation and horizon thermodynamics of stationary black holes
Diego Fernández-Silvestre, Alberto Guilabert, Pedro Bargueño +1
Black holes are the natural arena for exploring the interplay between gravity and thermodynamics. Although the association between black hole mechanics and black hole thermodynamic…
Traversable ghost wormholes
Alberto Guilabert, Ernesto Fuenmayor, Pedro Bargueño +1
Ghost stars are compact configurations characterized by an arbitrarily small total mass. Such objects require regions of negative energy density -a condition typically regarded as…
General Framework for the Spontaneous Scalarization of Regular Black Holes
Ernesto Contreras, Mikaela Carrasco-Hidalgo, Pedro Bargueño +1
We investigate the spontaneous scalarization of generic, static, and spherically symmetric regular black holes supported by nonlinear electrodynamics. Starting from an arbitrary se…
