R. Berardi, S. Orlandi, C. Zannoni, Monte Carlo simulations of discotic Gay-Berne mesogens with axial dipole, J. Chem. Soc. Faraday Trans. , 93, 1493-1496 (1997)

We have studied a system of N=103 discotic particles with central axial dipole using Monte Carlo computer simulations. We have investigated four temperatures corresponding to isotropic, nematic an columnar liquid crystal phases determining the molecular and dipolar distributions and the length of the polar domains in the columns.column

We find that dipolar monodomains in the column are not obtained in this hexagonal columnar system and the system is not ferroelectric.
