Abstract

The Landau phenomenological free-energy expansion in its discrete form is used to describe the free energy of each layer of a ferroelectric (FE) and antiferroelectric (AF) liquid crystalline system.  In order to study systematically the effect of electric field on phases, a simple free-energy model based on a five-layer system is considered, which includes only the usual van der Waals, nearest-neighbour and next nearest-neighbour interactions. Using the finite-difference time domain technique, numerical simulation based on the discrete-form of Landau-Khalatnikov equations of motion is performed to analyze the influence of electric field on the system. Changes in the phase structure are presented.
