摘要

Dusty plasma liquids are formed by suspending negatively charged micrometre sized particles in a low pressure discharge background. They are good candidates for studying the generic spatio-temporal dynamical behaviours at the kinetic level through direct optical video-microscopy due to the sub-mm interparticle spacing and the slow time scale. In this paper, starting from the basic picture of the avalanche type stick-slip cooperative hopping process under the interplay of mutual coupling and stochastic thermal agitation, we briefly review our recent study on particle micro-motion and the associated structural rearrangement. The effects of mesoscopic confinement and external. slow shear drive are also discussed.
