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