Thermodynamics, Phase Transitions, and Geodesic Structure of F(R)-Phantom Banados-Teitelboim-Zanelli (BTZ) Black Holes

Behzad Eslam Panah, Bilel Hamil, Manuel E. Rodrigues

This paper investigates phantom BTZ black holes within the high-curvature gravity theory framework, specifically using a special case of power-Maxwell theory, which functions as a…

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…

Complex bumblebee model

Willian Carvalho, A. C. Lehum, J. R. Nascimento +1

We formulate a renormalizable complex extension of the bumblebee theory in which the bumblebee field is promoted to a complex one and coupled to an Abelian gauge sector. Besides th…

Half-BPS Impurity Backgrounds and Supersymmetry

D. Bazeia, A. C. Lehum

We develop a rigid superspace framework for spatially inhomogeneous impurity deformations in dimensions by embedding the impurity profile into a real b…

Scattering amplitudes in dimensionless quadratic gravity coupled to QED

I. F. Cunha, A. C. Lehum

We study ultra-Planckian scattering in an Abelian gauge theory coupled to agravity, the scale-free and renormalizable realization of quadratic quantum gravity. Focusing on…

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…
