dc.description.abstractPatterns of orientational order in polar clusters arise from the tendency of dipolar particles to form chains in which the dipoles are in a head-to-tail configuration. These chains encircle the cluster leading to a pronounced circulating pattern. The circulating pattern is quite evident in minimum energy configurations of polar clusters, and is distinct. from orientational order in dipolar solids (much as the icosahedral translational order of rare gas clusters is distinct from the close packed structure of rare gas solids). Orientational order is surprisingly persistent at elevated temperatures in the model 13-particle cluster with Stockmayer interactions (Lennard-Jones + point dipoles) examined in our work. Quantified by an appropriate order parameter, we even detect the circulating pattern {above} the translational melting point.en_US
