A rich variety of structures is revealed as the cluster size and dipole strength are varied. Most remarkable are groups of closed-loop structures with the topology of knots and links. Despite the large number of possibilities, energetically optimal structures exhibit only a few such topologies.4 pages, 3 figuresSoft Condensed MatterMaterials ScienceStatistical Mechanicstext
