Metric-Induced Principal Symbols in Nonlinear Electrodynamics
Ãrico 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
Ãrico 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
Ãrico 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…
