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