Evading Cauchy horizon excision in scalarized regular black holes
Ernesto Contreras, Pedro Bargueño, Pedro Bargueño +1
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…
Logarithmic corrections to black hole entropy from minimum-assumptions discretization
Pelayo V. Calzada, Ana Alonso-Serrano, Ernesto Contreras +2
The paper presents a minimal-assumption model that discretizes a black‑hole horizon into Planck‑scale cells and uses combinatorial counting to derive the entropy area law together…
Horizon Microstructure Thermodynamics in AdS Black Holes: Smarr-Consistent Excitation Enthalpy
Juan Diego Haro, Ernesto Medina, Bertrand Berche +2
The paper models a four‑dimensional AdS black hole horizon as a collection of microscopic sites, using combinatorial counting to recover the Bekenstein–Hawking entropy and derive a…
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…
