MANY-PARTICLE ASPECTS OF THE THEORY OF TURBULENT PLASMA.

Abstract

The survey is devoted to an investigation of the weakly turbulent state of a rarefied plasma, when one can assume a weakly interacting gas of collective oscillations, 'quasi-particles,' on a 'background' of the average distribution of plasma particles. By describing the behavior of a rarefied plasma with the aid of the kinetic Boltzmann equations for the particle distribution functions and the Maxwellian equations for the self-consistant electrical and magnetic fields and by using the perturbation theory for a small ratio of the energy of interaction of collective oscillations among themselves and the 'background' to their full energy, in this case kinetic equations for the number of 'quasi-particles' are obtained. Representing the collective oscillations in the form of separate 'quanta' permits the expression of a number of properties of their nonlinear interaction in the simplest form. The quasi-linear theory is used to describe the interaction of oscillations with the 'background.' The application of the obtained equations is then illustrated on a series of specific examples.
