COMPUTER-SIMULATION OF CHIRAL LIQUID-CRYSTAL PHASES .2. THE USE OF TWISTED BOUNDARY-CONDITIONS

Using the Monte Carlo technique, we study an ensemble of N = 256 parti cles interacting via a chiral modified Gay-Berne potential introduced in part 1. We introduce twisted boundary conditions which allow the fo rmation of helical phases with lower potential energy and a larger pit ch in comparison with the results of simulations using cubic periodic boundary conditions. The amount of chiral and achiral energy contribut ions to the total potential energy are discussed for the obtained chol esteric, helical smectic and blue phases.
