Electrostatically driven granular media: phase transitions and coarsening

We report the experimental and theoretical study of electrostatically driven granular material. We show that the charged granular medium undergoes a hysteretic phase transition from the immobile condensed state (granular solid) to a fluidized dilated state (granular gas) with a changing applied electric field. In addition we observe a spontaneous precipitation of dense clusters from the gas pha...

Computer simulation of fluid phase transitions

The goal of accurately locating fluid phase boundaries by means of computer simulation is hampered by difficulties associated with sampling both coexisting phases in a single simulation. We explain the background to these difficulties and describe how they can be tackled using a synthesis of biased Monte Carlo sampling and histogram extrapolation methods, in conjunction with a standard fluid si...

NUMERICAL SIMULATIONS OF THE PHASE TRANSITIONS IN CLUSTERS

We have studied the phase transitions in atomic clusters by molecular dynamics simulation, assuming Lennard-Jones interatomic pair potential. Calculations are performed by DAP parallel computer. The results are analyzed by simulating their orientational distribution plots (dot-plot), and neutron diffraction patterns. It is shown that all the main features of the bulk phase transitions are e...
