ABSTRACT
The experimental and theoretical study of electrostatically driven granular material are reported. It is shown that the charged granular medium undergoes a hysteretic first order phase transition from the immobile condensed state (granular solid) to a fluidized dilated state (granular gas) with a changing applied electric field. In addition a spontaneous precipitation of dense clusters from the gas phase and subsequent coarsening-coagulation of these clusters is observed. Molecular dynamics simulations shows qualitative agreement with experimental results. © 2000 American Institute of Physics.
