Drift wave turbulence and associated transport in a collisional dusty magnetoplasma

A set of nonlinear equations for the low-frequency, long and short wavelength (in comparison with the ion gyroradius) electrostatic drift waves in a nonuniform collisional dusty magnetoplasma is derived. In the linear limit, the presence of stationary charged dust grains is found to enhance the frequency and the growth rate of the long wavelength drift wave instability. Subsequently, nonthermal drift wave fluctuations induced cross-field plasma particle transport is also enhanced. Furthermore, nonlinear mode coupling equations for long and short wavelength drift waves are useful for studying the formation of structures and zonal flows in nonuniform collisional dusty magnetoplasmas, such as those in the Earth's mesopshere and cometary tails where collisional interactions between the electrons and ions with neutrals play an essential role.
