Stochastic Thermodynamics of Dynamical Thin-Shell Wormholes: Effective Temperatures, Fluctuations and Conditional Quasi-Horizon Unification
Francisco S. N. Lobo, Manuel E. Rodrigues
We develop an effective stochastic and semiclassical framework for dynamical thin-shell wormholes connecting two asymptotic spacetime regions. The Israel junction geometry is separ…
Accretion dynamics of thin and thick disks in charged Kalb-Ramond black holes
Ednaldo L. B. Junior, José Tarciso S. S. Junior, Francisco S. N. Lobo +5
In this work, we investigate the accretion properties of an electrically charged, static, spherically symmetric black hole in Kalb-Ramond (KR) gravity, where a dimensionless parame…
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 classical formation of a Schwarzschild black hole from a regular, non-singular configuration has recently been shown to be impossible within general relativity: the geometry in…
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…
Black bounce solutions in a realistic dark matter halo from M60*
Ednaldo L. B. Junior, José Tarciso S. S. Junior, Francisco S. N. Lobo +5
We formulate a Simpson-Visser black bounce solution embedded in a dark matter halo. The latter is modeled using an empirical density profile calibrated from observations of the ell…
Linearized stability of T-duality quantum-inspired thin-shell wormholes
Francisco S. N. Lobo, Manuel E. Rodrigues
Wormholes that are traversable in principle offer fascinating insights into general relativity, yet they typically require exotic matter and suffer from stability issues. We constr…
Black Bounce Solutions from a Self-Interacting 3-Form Field in General Relativity
Francisco S. N. Lobo, Manuel E. Rodrigues
We construct a new class of black-bounce solutions sourced by a self-interacting 3-form field minimally coupled to general relativity and a scalar field. The 3-form field, which na…
Lorentz-violating signatures in quasi-periodic oscillations from a magnetised Kalb-Ramond black hole
Luiz F. G. Rodrigues, Francisco S. N. Lobo, Manuel E. Rodrigues
We investigate the dynamics of charged particles around a Schwarzschild-like black hole sourced by a Kalb-Ramond field and immersed in a uniform external magnetic field. The Kalb-R…
Scalar-Electromagnetic Couplings as Source of Deformed Black Hole: From Shadows to Thermodynamic Topology
Ednaldo L. B. Junior, José Tarciso S. S. Junior, Francisco S. N. Lobo +5
We reconstruct a static and spherically symmetric black hole geometry originally proposed as an effective metric by identifying a consistent matter source derived from a fundamenta…
Dyonic Ellis-Bronnikov wormholes from warped extra dimensions
Francisco S. N. Lobo, Miguel A. S. Pinto, Manuel E. Rodrigues
We investigate traversable wormhole solutions within a four-dimensional effective theory derived from a five-dimensional Einstein-Maxwell-Chern-Simons action with a non-minimally c…
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…
