Inverse Reconstruction of Causal Nonlinear Electrodynamics: Functional Families, Spectral Constraints, and Single-Horizon Black Holes
Ariel Guzmán, Mohsen Fathi, J. R. Villanueva
Nonlinear electrodynamics (NLED) admits many causal theories, so causality alone does not provide a unique selection principle. We formulate an inverse construction in which consti…
Dark-Sector Effects on the Phase Structure of Nonlinear Magnetic AdS Black Holes
Carlos E. Romero-Figueroa, J. R. Villanueva
We investigate the effects of perfect fluid dark matter (PFDM) and a dark-energy field on the phase structure of a nonlinear magnetically charged Anti--de Sitter (NLMC--AdS) black…
A causal magnetic black hole with finite self-energy
Mohsen Fathi, Ariel Guzmán, J. R. Villanueva
We construct a nonlinear electrodynamics (NLED) model for a static magnetic black hole. Rather than imposing a regular center, we require a Maxwell weak-field limit, finite magneti…
Quasinormal modes of a static black hole in nonlinear electrodynamics
Mohsen Fathi, Ariel Guzmán, J. R. Villanueva
We investigate the axial electromagnetic quasinormal modes of a static, asymptotically Anti--de Sitter (AdS) black hole sourced by a nonlinear electrodynamics model of Plebański ty…
Interacting Generalized Chaplygin-Jacobi gas: Thermodynamics approach
Gilberto Aguilar-Pérez, Miguel Cruz, Mohsen Fathi +1
This work investigates a cosmological model featuring an interaction between dark energy and dark matter, where the dark energy component is described by the Generalized Chaplygin-…
Cosmological evolution driven by polytropic fluids in an inhomogeneous spacetime
Gilberto Aguilar-Pérez, Miguel Cruz, Mohsen Fathi +2
Addressing the late-time accelerated expansion of the universe, known as the "dark energy problem", remains a central challenge in cosmology. While the cosmological constant is the…
