Paper Abstract

We have performed Monte Carlo simulations for elongated molecules assuming an ideal orientational order. The intermolecular forces were derived form the Gay-Bernes model, where the long molecular axis were taken parallel to the z-direction. Additionally, we included dipole-dipole interactions by adding permanent dipoles along z. The dipoles were allowed to be oriented either up or down, similar to spin configurations in the Ising model. Their interactions were evaluated by using the Ewald summation technique.By changing temperature and the magnitude of the molecular dipoles we found an ideal nematic phase, smectc A1 or A2 phases.
