Low-frequency electrostatic modes in partially ionized complex plasmas: a kinetic approach
2012 (English)In: New Journal of Physics, ISSN 1367-2630, Vol. 14, 013002- p.Article in journal (Refereed) Published
A kinetic model of partially ionized complex plasmas is employed for the numerical analysis of low-frequency longitudinal modes for typical laboratory plasmas. The approach self-consistently includes the effects of plasma particle absorption on dust, collisions with neutrals and electron impact ionization. In addition to the typical dust acoustic mode, the results reveal the existence of a novel long-wavelength mode, attributed to the interplay between the mechanisms of plasma production and loss. The main properties of mode dispersions are investigated through their dependence on plasma and dust parameters.
