摘要：

We study the effect of molecular dipole strength on the polymorphism of smectic A liquid crystals using computer simulations and density functional theory. We find, for a system of polar Gay-Berne particles with an off-centre axial dipole, a change in molecular organisation from non-interdigitated to interdigitated (S-A d) structure.
