Dust charging processes in the dusty plasma with nonextensive power-law distribution    [PDF]

Gong Jingyu, Du Jiulin

The dust charging processes by the collections of electrons and ions in the dusty plasma with power-law distributions are investigated on the basic of the theory in nonextensive statistics. Electrons and ions in the plasma obey the power-law distributions with q-parameters different from each other. We derive the general formulae generalized for the dust charging currents in which the nonextensive effects play roles. Further we investigate the dust charging processes taking place in the homogeneous dusty plasma where the velocities are power-law distributions and in the dust cloud plasma where the velocities and the densities are both power-law distributions. By numerical analyses we show that the nonextensive power-law distributions of electrons and ions in the dusty plasma have significant effects on the dust charging processes.
