On a kinetic theory for strongly coupled dusty plasmas
- Department of Physics and Astronomy, University of Iowa, Iowa City, Iowa 52246 (United States)
A kinetic theory for strongly coupled dusty plasmas is developed from the Bogolyubov{endash}Born{endash}Green{endash}Kirkwood{endash}Yvon (BBGKY) hierarchy. In these plasmas, interparticle distances are typically much smaller than the Debye length, and the coupling parameter {Gamma}{sub {ital d}}{equivalent_to}{ital q}{sup 2}{sub {ital d}}/{ital d}{sub {ital dT}}{sub {ital d}} is much larger than unity. {bold (}Here {ital q}{sub {ital d}} is the dust charge, {ital T}{sub {ital d}} is the temperature, and {ital d}{sub {ital d}}{equivalent_to}[3/(4{pi}{ital n}{sub {ital d}})]{sup 1/3} is the inter-dust-particle distance.{bold )} For such quasi-steady-state plasmas, a theoretical argument is given for the validity of the Vlasov equation in the regimes {Gamma}{sub {ital d}}{lt}1 and {Gamma}{sub {ital c}}{gt}{Gamma}{sub {ital d}}{gt}1, where {Gamma}{sub {ital c}} designates the coupling parameter when Coulomb crystallization occurs. {copyright} {ital 1996 American Institute of Physics.}
