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 ...

Abstract In formulating the Maxwell equations for electrodynamics in the presence of a macroscopic continuous medium, it is common among standard textbooks to simply borrow expressions for the polarization charges and magnetization currents derived in electrostatics and magnetostatics, without much explicit justifications for using them in electrodynamics. Here we emphasize that these quantitie...

Analyzing the constraint structure of electrodynamics, massive vector bosons, Dirac fermions and electrodynamics coupled to fermions, we show that Dirac quantization method leads to appropriate creationannihilation algebra among the Forier coefficients of the fields. e-mail: [email protected]

The (2+1) dimensional non-linear electrodynamics, the so called Pagels–Tomboulis electrodynamics, with the Chern–Simons term is considered. We obtain ”generalized self–dual equation” and find the corresponding generalized massive Chern–Simons Lagrangian. Similar results for (2+1) massive dilaton electrodynamics have been obtained. 1 The Pagels–Tomboulis model Among many gauge theories the Pagel...

We show that correlators of the gauge field in 3D electrodynamics with N flavors of massless matter can be obtained, in the leading order of the large N expansion, from solutions of free classical electrodynamics in a 4D half-space for which the 3D space is the boundary. The Abelian gauge fields of the two theories are dual to each other. We conjecture that for 3D scalar electrodynamics this du...

We sketch the foundations of classical electrodynamics, in particular the transition that took place when Einstein, in 1915, succeeded to formulate general relativity. In 1916 Einstein demonstrated that, with a choice of suitable variables for the electromagnetic field, it is possible to put Maxwell’s equation into a form that is covariant under general coordinate transformations. This unfolded...

In the present work a number of questions concerning foundations of the classical electrodynamics is discussed. First of all they are the law of the energy conservation and the introduction of particles in the classical electrodynamics. We pay attention to a logic error which takes place at an interpretation of the Poynting's theorem following from the equations of Maxwell-Lorentz as the law of...
