Kinetics of relativistic axionically active plasma in the field of dynamic aether. Part II: Particle dynamics and symptoms of plasma instability

In the paper [I], the first part of our work, we established the model of interaction of five elements: first, a unit time-like vector field, associated with the velocity of dynamic aether, second, the pseudoscalar field describing an axionic component of the dark matter, third, the electromagnetic field, fourth, the relativistic multi-component plasma and, fifth, the gravitational field. The initial step of analysis of this model was the reconstruction of the equilibrium states of the axionically-aetherically active plasma, which are characterized by frequent inter-particle collisions. In the second part of the work, presented here, in the framework of isotropic homogeneous cosmological model we consider the collisionless limit of the theory, and thus, we focus on the analysis of the particle dynamics under the influence of axionically-aetherically induced forces. The complete distribution functions, as exact solutions to the kinetic equations, are presented. Based on five examples of the background solutions of the model, we discuss the symptoms of plasma instability provoked by the influence of forces of the friction and tidal types.
