Dust charging processes in the nonequilibrium dusty plasma with nonextensive power-law distribution
The dust charging processes in the collections of electrons and ions in the
nonequilibrium dusty plasma with power-law distributions are investigated on
the basic of a new q-distribution function theory in nonextensive statistics.
Electrons and ions obey the power-law distributions and are with q-parameters
different from each other. We derive the generalized formulae 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 only the particle velocities are power-law distributions and in
the dust cloud plasma where the particle velocities and densities are both
power-law distributions. By numerical analyses, we show that the nonextensive
power-law distributions of electrons and ions have significant effects on the
dust charging processes in the nonequilibrium dusty plasma.Comment: 16 pages, 6 figures, 51 reference
