“…(see. e.g., [24,27,28,43]). Since the gradient fourvector ∇ k φ contains the longitudinal part U k Dφ ≡ U k U l ∇ l φ, and since the four-vector B i = F * ik U k describes the magnetic induction in the medium, we can consider the pseudoscalar c 4π Dφ as the parameter of axionically induced magnetic conductivity in analogy with the electric conductivity σ.…”

The state of a static spherically symmetric relativistic axionically active multi-component plasma in the gravitational, magnetic and electric fields of an axionic dyon is studied in the framework of the Einstein -Maxwell -Fermi -Dirac -axion theory. We assume that the equations of axion electrodynamics, the covariant relativistic kinetic equations, and the equation for the axion field with modified periodic and Higgs-type potentials are nonlinearly coupled; the gravitational field in the dyon exterior is assumed to be fixed and to be of the Reissner-Nordström type. We introduce the extended Lorentz force, which acts on the particles in the axionically active plasma, and analyze the consequences of this generalization. The analysis of exact solutions, obtained in the framework of this model for the relativistic Boltzmann electron-ion and electron-positron plasmas, as well as, for degenerated zero-temperature electron gas, shows that the phenomena of polarization and stratification can appear in plasma, attracting attention to the axionic analog of the known Pannekoek-Rosseland effect.

We consider dark fluid as a medium, which acts indirectly on cosmic electromagnetic fields of all types. We develop mathematical models for dark analogs of pyromagnetic, piezomagnetic and dynamo-optical effects, magnetostriction and optical activity in minimal and nonminimal versions.Keywords: Dark fluid; axion electrodynamics; MG14 Proceedings. Dark Fluid as an Electromagnetically Active MediumDark fluid composed of a dark energy and dark matter has a status of a key constitutive element of modern cosmological models (see, e.g., 2− 6 for review, references and terminology). Both the dark energy and dark matter are assumed to consist of electrically neutral particles and thus the dark fluid does not interact with an electromagnetic field directly.Electrodynamic systems of the Universe are incorporated into the baryonic matter (its modern contribution into the Universe energy balance is estimated as 5%). On the one hand, these electrodynamic systems form the basic channel of the information about the Universe structure; on the other hand, they are subordinate elements from the point of view of the Universe energy distribution. In this context each cosmic electrodynamic system can be considered as a marker, which signalizes about the variations in the state of the dark fluid, the energetic reservoir, into which this marker is immersed.We are interested to answer the question: what mechanisms might be responsible for a (possible) transmission of information about the dark fluid state to the electrodynamic systems. These mechanisms could help to reconstruct features of the dark fluid evolution, e.g., by tracking down specific fine details of the spectrum of observed electromagnetic waves, of their phase and group velocities.Classification, review and discussion about schemes of mathematical description of these marker-effects are the main purposes of the presented talk. Let us focus, first, on the list of models, which describe the indirect influence of the dark fluid on the electromagnetic fields of various structure. The key idea is that the dark fluid can be considered as a specific cosmic medium in which the electromagnetic fields evolve. In this sense we can attract the attention to effects well-known and welltested in the electrodynamics of moving polarizable/magnetizable continuous media in classical (relativistic) theory. For this purpose, in addition to the Maxwell tensor F ik , which describes the electromagnetic field strength, one uses the excitation

“…The most interesting models, of course, are the models with dipole and quadruple moments, since they, in principle, can be tested using spectroscopic technics. The multipole structure of the electromagnetic field for the case of relic dark matter axions was analyzed in [28] on the example of weak gravitational field of the Earth. Now we consider the relativistic model of magnetic star with strong magnetic, gravitational, pseudoscalar (axion) fields and axionically induced electric field.…”

In the framework of Einstein-Maxwell-axion theory we consider a static field configuration in the outer zone of a magnetic star. We assume that this field configuration is formed by the following interacting quartet: a spherically symmetric gravitational field of the Reissner-Nordström type, pseudoscalar field, associated with an axionic dark matter, strong intrinsic magnetic field, and axionically induced electric field. Based on the analysis of the solutions to the master equations of the model, we show that the structure of the formed field configuration reveals the following triple effect. First, if the strong magnetic field of the star has the dipole component, the axionic halo around the magnetic star with spherically symmetric gravitational field is no longer spheroidal, and the distortion is induced by the axion-photon coupling; second, due to the distortion of the axionic halo the magnetic field is no longer pure dipolar, and the induced quadruple, octupole, etc., components appear thus redistributing the magnetic energy between the components with more steep radial profiles than the dipolar one; third, the interaction of the axionic and magnetic fields produces the electric field, which inherits their multipole structure. We attract attention to possible applications of the predicted field restructuring to the theory of axionic rotating magnetars.
