Phys. Rev. Lett. 94, 027802 (2005) [4 pages]Direct Computation of the Twist Elastic Coefficient of a Nematic Liquid Crystal Via Monte Carlo SimulationsReceived 1 June 2004; published 19 January 2005 A direct method for the computation of the twist Frank elasticity coefficient of a nematic liquid crystal is presented. The method, suitable for numerical calculations, is tested and applied in Monte Carlo simulations for a model system. The dependence of the elasticity coefficient on the temperature and density and its relation to the nematic order parameter are analyzed and discussed. © 2005 The American Physical Society URL:
