Bertotti-Robinson and Bonnor-Melvin universes in nonlinear electrodynamics
David Kubiznak, Otakar Svitek, Tayebeh Tahamtan
We review the status of Birkhoff's theorem in the presence of nonlinear electrodynamics (NLE) - extending the analysis to the case without asymptotic flatness. This leads to the Be…

Orbital Motion in Spacetimes Influenced by the Presence of Scalar and Electromagnetic Fields
J. Horák, T. Tahamtan, T. Hale +3
The study investigates orbital motion of test particles near compact objects described by solutions involving massless scalar fields, electromagnetic fields, and nonlinear electrod…

Regularized Conformal Electrodynamics: Novel C-metric in (2+1) Dimensions
David Kubiznak, Otakar SvÃtek, Tayebeh Tahamtan
Conformal electrodynamics is a particularly interesting example of power Maxwell non-linear electrodynamics, designed to possess conformal symmetry in all dimensions. In this paper…
