Transverse dipole-dipole effective interaction for sheet arrangements

摘要

We have succeeded to develop a model pair interaction which when added to asystem of interacting particles can be tuned to arrange the interacting objectsinto sheets. The interaction is based on the decomposition of the dipole-dipoleinteraction into two components, one parallel and one perpendicular to theconnecting line between the dipoles, and keeping only perpendicular part here.Various aspects of this simple interaction are discussed, in particular inconnection to two recent papers on self assembly of carbon nanostructures. Onthe other hand, the features discussed are quite general and might be ofinterest in different areas of microscopic modeling.
