Landau damping of dust acoustic waves in the plasma with nonextensive distribution
The Landau damping of dust acoustic waves propagating in a dusty plasma composed of nonextensive distributed electrons and ions, and Maxwellian distributed dust grains is investigated based on kinetic theory. The dust acoustic waves are found in the range of kvd≪ω≪kvi≪kve, where vα is the thermal velocity of species α(=i,e,d). The damping rate is shown to be dependent on the nonextensivity parameter q as well as the ratio of ion density to electron. In the limit q→1, the result based on the Maxwellian distribution is recovered. The maximum Landau damping rate is found to be enhanced as the population of the electron density decreases.
