New solid phase of dipolar systems
(Laboratoire de Physique Théorique, CNRS, Université de Paris-Sud, Université de Paris-Saclay, Bâtiment 210, 91405 Orsay Cedex, France)
The systems of molecules with a permanent dipole moment have solid phases with various crystal symmetries. In particular, the solid phases of the simplest of these systems,
the dipolar hard sphere model, have been extensively studied in the literature. The article presents Monte Carlo simulation results which, at low temperature, point to the stability
of a polarized solid phase of dipolar hard spheres with the unusual number of eleven nearest neighbors, the so-called primitive tetragonal packing or tetragonal close packing.
