Quasiparticles in macroscopically agitated magnetized plasma

In order to explain observations of either laboratory or space plasmas, it is possible to allow for the occurrence of fluid-like turbulent motion in the plasma, which can be produced by large-scale and low-frequency electromagnetic fields, generated either by some external factors or internally, for example due to magnetohydrodynamic turbulence. In this paper the effect of fluid-like motion on the low-frequency fluctuations in the magnetized plasma is studied. The spectral distributions of fluctuations are derived and explained in terms of macro-particles originating from plasma turbulent agitation. (orig.)
