Journal ArticleDOI
Geometrical aspects of light propagation in nonlinear electrodynamics
TL;DR: In this paper, the propagation of light in the context of nonlinear electrodynamics, as it occurs in modified QED vacua, is analyzed in terms of a modification of the effective geometry of the underlying spacetime structure.
Journal ArticleDOI
Nonlinear electrodynamics and FRW cosmology
TL;DR: In this paper, a mathematical toy model is proposed for the analytical nonsingular extension of FRW solutions, which is obtained for a class of nonlinear generalizations of the electromagnetic theory.
Journal ArticleDOI
Light propagation in non-linear electrodynamics
TL;DR: In this paper, the light cone conditions for a class of theories constructed with the two gauge invariants of the Maxwell field without making use of average over polarization states were obtained for the Euler-Heisenberg effective Lagrangian.
Journal ArticleDOI
Electromagnetic wave propagation inside a material medium: an effective geometry interpretation
V. A. De Lorenci,M. A. Souza +1 more
TL;DR: In this article, a method for dealing with electromagnetic wave propagation inside a material medium that reacts, in general, nonlinearly to the field strength is presented. But this method is restricted to the isotropic case and artificial birefringence caused by an external electric field.
Journal ArticleDOI
Analogue black holes in flowing dielectrics
TL;DR: In this article, it was shown that a flowing dielectric medium with a linear response to an external electric field can be used to generate an analogue geometry that has many of the formal properties of a Schwarzschild black hole for light rays, in spite of birefringence.
