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…

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…
