Influence of external perturbations on dynamical characteristics of dust clusters (simulation)

The results of a numerical study of the dynamics of interacting particles in cluster systems under the action of an external perturbing field on them are presented. The relaxation rates and characteristic relaxation times of a cluster to its equilibrium state are analyzed. The conditions for the for...

Summary:The results of a numerical study of the dynamics of interacting particles in cluster systems under the action of an external perturbing field on them are presented. The relaxation rates and characteristic relaxation times of a cluster to its equilibrium state are analyzed. The conditions for the formation of dynamical structures of charged particles in the field of external nonpotential forces are investigated. The peculiarities of diagnosing the pair potential of particles in nonequilibrium systems are considered. The numerical simulation conditions for the problem were close to the conditions of experiments in a dusty plasma.
