Abstract
In the plasma-dust system Brownian motion replaces thermal agitation, because the strong friction of the air robs the dust of its kinetic en ergy almost instantly. Numerical simulation shows that, in the presenc e of Debye screening, a liquid-solid transition may take place when th e Coulomb potential is extremely strong, in accord with experimental o bservations.
