MONTE-CARLO INVESTIGATIONS OF A GAY-BERNE LIQUID-CRYSTAL

We report extensive Monte Carlo simulations of two systems with 512 and 1000 particles interacting with a Gay-Berne potential with strength parameters (mu = 1, nu = 3) that enhance the side-by-side and end-to-end interactions between the particles. We show that the system has a smectic, nematic and isotropic phase and we calculate the order parameters < P-2 >, < P-4 >, the intermolecular vector distribution and other relevant observables as a function of temperature at a scaled density p(*) = 0.30.
