Gravitational Effects on Light Propagation in Linear Magnetoelectrics and Plasmas
Elda Guzmán-Herrera, Vitorio A. De Lorenci, Renato Klippert
A covariant formalism for electromagnetism is used to investigate the effects of light propagation within certain material systems under the influence of a background gravitational…
Nonlinear electrodynamics in magnetars: systematic effects on radius constraints and timing analysis
Gabriel A. Porto, Jonas P. Pereira, Eduardo Bittencourt +1
Magnetars are among the most extreme laboratories in the universe, harboring surface magnetic fields reaching ~G. At these supercritical scales, Maxwell's linear electrody…
Exploring light propagation in nonlinear electrodynamics: phase and group velocities and related phenomena
T. W. Cruz, V. A. De Lorenci, E. Guzmán-Herrera +1
Nonlinear electrodynamics has been an important area of research for a long time. Investigations based on nonlinear Lagrangians, such as Euler-Heisenberg and Born-Infeld, are instr…
Comparative of light propagation in Born-Infeld, Euler-Heisenberg and ModMax nonlinear electrodynamics
Elda Guzman-Herrera, Ariadna Montiel, Nora Breton
We compare light propagation through an intense electromagnetic background as described by three different nonlinear electrodynamics: Born-Infeld (BI), Euler-Heisenberg (EH), and M…
Euler-Heisenberg waves propagating in a magnetic background
Elda Guzman-Herrera, Nora Breton
We derive the Euler-Heisenberg solutions that describe electromagnetic waves propagating through very intense uniform magnetic or electric background, with the effective metric app…
