Abstract:Particle transport is also affected by Coulomb interactions between particles. Experimental observations showed that in trapping sites particles form clouds and move collectively. We numerically investigated Coulomb interactions between particles. In rf discharges, ordered systems (Coulomb liquids or solids) occur at low particle temperatures. Dislocations in lattices result because of impurities of differently sized particles due to the disparity in particle charges. Waves may be induced by impacting a Coulomb solid with energetic particles. Repeated impacts can liquify the lattice if the particles do not dissipate enough energy as a result of fluid drag effects or Coulomb collisions.
