Riemannian light cone from vanishing birefringence in premetric vacuum electrodynamics
We consider premetric electrodynamics with a local and linear constitutive law for the vacuum. Within this framework, we find quartic Fresnel wave surfaces for the propagation of light. If we require vanishing birefringence in vacuum, then a Riemannian light cone is implied. No proper Finslerian structure can occur. This is generalized to dynamical equations of any order.
متن کاملElectric/magnetic reciprocity in premetric electrodynamics with and without magnetic charge, and the complex electromagnetic field
We extend an axiomatic approach to classical electrodynamics, which we developed recently, to the case of non-vanishing magnetic charge. Then two axioms, namely those of the existence of the Lorentz force (Axiom 2) and of magnetic flux conservation (Axiom 3) have to be generalized. Electric/magnetic reciprocity constitutes a guiding principle for this undertaking. The extension of the axioms ca...

The premetric approach to electrodynamics provides a unified description of a wide class of electromagnetic phenomena. In particular, it involves axion, dilaton and skewon modifications of the classical electrodynamics. This formalism emerges also when the non-minimal coupling between the electromagnetic tensor and the torsion of Einstein-Cartan gravity is considered. Moreover, the premetric fo...
متن کاملWave propagation in axion electrodynamics
In this paper, the axion contribution to the electromagnetic wave propagation is studied. First we show how the axion electrodynamics model can be embedded into a premetric formalism of Maxwell electrodynamics. In this formalism, the axion field is not an arbitrary added Chern-Simon term of the Lagrangian, but emerges in a natural way as an irreducible part of a general constitutive tensor. We ...
متن کاملMaxwell’s equations in Minkowski’s world: their premetric generalization and the electromagnetic energy-momentum tensor
In December 1907, Minkowski expressed the Maxwell equations in the very beautiful and compact 4dimensional form: lor f = −s, lor F ∗ = 0. Here ‘lor’, an abbreviation of Lorentz, represents the 4dimensional differential operator. We study Minkowski’s derivation and show how these equations generalize to their modern premetric form in the framework of tensor and exterior calculus. After mentionin...
