Metric-Induced Principal Symbols in Nonlinear Electrodynamics
Érico Goulart, Eduardo Bittencourt
We present a geometrical formulation of nonlinear electrodynamics by expressing its principal symbol as an optical metric-induced object. Under the assumption of no birefringence,…
Propagation features of Lorentz-violating electrodynamics
E. Goulart, J. E. Ottoni, J. C. C. Felipe
This paper explores some propagation features of electrodynamics in a Lorentz-violating scenario, focusing on a specific CPT-even term within the photon sector of the Standard Mode…
Mimicking a rotating black hole with nonlinear electrodynamics
Érico Goulart, Eduardo Bittencourt
We exhibit the first analogue model of a rotating black hole constructed in the framework of nonlinear electrodynamics. The background electromagnetic field is assumed to be algebr…
Photon traps in nonlinear electrodynamics
Érico Goulart, Eduardo Bittencourt
We demonstrate the existence of photon traps within the framework of nonlinear electrodynamics. The trapping mechanism is based on the fact that, for null background fields, the op…
From disformal electrodynamics to exotic spacetime singularities
Eduardo Bittencourt, Ricardo Fernandes, Érico Goulart +1
We study different types of spacetime singularities which emerge in the context of disformal electrodynamics. The latter is characterized by transformations of the background metri…
Non-linear electrodynamics non-minimally coupled to gravity:symmetric-hyperbolicity and causal structure
Érico Goulart, Santiago Esteban Perez Bergliaffa
It is shown here that symmetric hyperbolicity, which guarantees well-posedness, leads to a set of two inequalities for matrices whose elements are determined by a given theory. As…
From Hopf fibrations to exotic causal replacements
Miguel Bezares, Érico Goulart, Gonzalo Palomera +2
Topological solitons are relevant in several areas of physics [1]. Recently, these configurations have been investigated in contexts as diverse as hydrodynamics [2], Bose-Einstein…
