摘要

Temperature driven first order transition from isotropic to nematic phase in liquid crystals with and without random and quenched orientational disorder is investigated employing multicanonical Monte Carlo simulation. A lattice model with periodic boundary conditions is employed with the pair wise interaction of two nearest neighbour liquid crystal molecules given by the Lebwohl-Lasher potential. The transition temperature decreases with increase of disorder; also the transition appears to soften under strong disorder.
