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…

Homogeneous and Isotropic Linearized Gravity as a Caldeira--Leggett System
Pelayo V. Calzada, Pedro Bargueño
The paper demonstrates that homogeneous and isotropic linearized gravity can be mapped onto a Caldeira–Leggett open‑system model, yielding a generalized Langevin equation for metri…

Static and spherically symmetric vacuum spacetimes with non-expanding principal null directions in gravity
Alberto Guilabert, Pelayo V. Calzada, Pedro Bargueño +1
In this work we characterize all the static and spherically symmetric vacuum solutions in gravity when the principal null directions of the Weyl tensor are non-expanding. In…
