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…
Regular Black Holes in General Relativity from Nonlinear Electrodynamics with de Sitter Cores
A. A. Araújo Filho, Ednaldo L. B. Junior, José Tarciso S. S. Junior +6
We present new regular black hole solutions in general relativity (GR) within a static, spherically symmetric framework governed by a variable equation of state, following the appr…
Generalized Unruh temperature for dynamical thin-shell wormholes
Francisco S. N. Lobo, Manuel E. Rodrigues
We unify two independent notions of effective temperature in dynamical thin-shell wormholes: the local acceleration temperature of the throat and the Hawking-like particle-creation…
Thermodynamics of thin-shell wormholes
Francisco S. N. Lobo, Manuel E. Rodrigues
We develop a unified thermodynamic description of dynamic thin-shell wormholes, starting from the transparent (vacuum bulk) case and then relaxing the transparency condition to inc…
