Light propagation in (2+1)-dimensional electrodynamics: the case of nonlinear constitutive laws
Eduardo Bittencourt, Elliton O. S. Brandão, Érico Goulart
We scrutinize the geometrical properties of light propagation inside a nonlinear medium modeled by a fully covariant electromagnetic theory in -dimensions. After setting the n…
Light propagation in (2+1)-dimensional electrodynamics: the case of linear constitutive laws
Érico Goulart, Eduardo Bittencourt, Elliton O. S. Brandão
In this paper, we turn our attention to light propagation in three-dimensional electrodynamics. More specifically, we investigate the behavior of light rays in a continuous bi-dime…
On the intrinsically flat cosmological models in a lattice
Eduardo Bittencourt, Leandro G. Gomes, Grasiele B. Santos
In this manuscript we investigate the intrinsically flat (space-flat) spacetimes as viable cosmological models. We show that they have a natural geometric structure which is suitab…
