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.
