Dynamics in a multicomponent plasma near the low-frequency cutoff.
The distinctive feature of a multicomponent plasma is found to be a first order rotation of the light ion fluid with a characteristic frequency, Omega(r). A resonance at omega=Omega(r) results in plasma oscillation with unique properties. Coupling of the fast rotation time scale with the slow magnetosonic time scale leads to a nonlinear Schro dinger equation for the system and suggests the possibility of strong structural turbulence at MHD scales.
