Interpretable Causal Discovery via Causal-Effect Constraints
Cixuan Zhang, Guy Van den Broeck, Benjie Wang
Causal discovery aims to uncover the underlying causal relationships given data generated from a system. The goal, however, is not merely to predict causal edges given data, but al…
Scalaron-modified null focusing and radial monotonicity in static f(R) gravity
Maickol Muñoz-Palma, Francisco S. N. Lobo, Jean Báez Cuevas +1
We derive an exact radial monotonicity law for static, spherically symmetric spacetimes in metric \(f(R)\) gravity. For \(ds^2=A(r)dt^2-dr^2/B(r)-r^2dΩ^2\), the matter contribution…
Black bounce sourced by non-minimally coupled linear electrodynamics and a canonical scalar field through a thin shell at the throat
Ednaldo L. B. Junior, José Tarciso S. S. Junior, Francisco S. N. Lobo +5
We construct a novel class of black bounce solutions within General Relativity, sourced by a canonical scalar field non-minimally coupled to linear electrodynamics, establishing a…
Entropy dynamics in gravitational collapse: From Minkowski breaking to de Sitter thermodynamics
Francisco S. N. Lobo, Manuel E. Rodrigues
The origin of black hole entropy remains one of the deepest mysteries in modern physics. Two recent developments offer complementary perspectives on this puzzle: the entropy releas…
Entropy release from Minkowski breaking in regular Schwarzschild black holes
Francisco S. N. Lobo, Manuel E. Rodrigues
The paper examines how regular Schwarzschild black holes with a de Sitter core possess an inner Killing horizon that carries Bekenstein‑Hawking entropy, which must be released when…
Thin-shell wormholes in cosmic voids
Jonathan A. Rebouças, Edson Otoniel, Francisco S. N. Lobo
The paper constructs symmetric thin‑shell wormholes by joining two copies of a black‑hole region inside a cosmic void, derives the shell’s stress‑energy via Darmois‑Israel junction…
