A model for the freezing transition where a crystalline seed induces symmetry breakage is discussed. The seed is an array of sticky sites and we have analyzed the case of vanishing sticky potential. We consider a two-dimensional lattice and show that, within the framework of the Yang and Lee...

The dielectric properties of a crystal made of several interpenetrating lattices of ions and reorientable permanent point dipoles are investigated. The ions and dipoles are both assumed to be polarizable. A set of functions ni is introduced to describe the orientational disordering of the...
