Abstract:
The structure of dusty plasma clusters in the ground state for various configurations of the confining field has been simulated using the molecular dynamics method with the interaction between spherical particles of dusty plasma described in terms of an isotropic Yukawa pair potential. Depending on the degree of the confining field anisotropy (i.e., a difference between forces in the vertical and horizontal directions), conditions for which a three-dimensional (3D) structure in the ground state (isotropic confining field) transforms into a 2D structure are determined. The shape, dimensions, and structure of dusty plasma clusters have been studied in systems with various numbers of particles and degrees of anisotropy of the confining field.
