Nonequilibrium dynamics of chiral liquid crystal films

Abstract

We propose a model with two order parameters, introducing a chiral order parameter field in addition to the so-called c-vector field which denotes the in-plane orientation of the liquid crystal molecules. In terms of these two fields we construct a phenomenological model which describes nonequilibrium dynamics of chiral liquid crystal films. Using this model, we show numerically that a finite amplitude perturbation causes self-organized formation of the target patterns associated with the orientation which is observed in the experiments.
