Abstract

We carry out a numerical study to investigate how a cholesteric blue phase responds to an electric field. Our study is based on a Landau-de Gennes continuum theory that describes the orientational order of a liquid crystal in terms of a second-rank tensor. Our numerical scheme allows the change in the size and shape of the unit cell in the course of relaxation to obtain an equilibrium profile of the orientational order. We find a distortion of the unit cell of blue phases under a weak field, which reproduces qualitatively the previous experimental findings. We also observe a rearrangement of disclination lines when a strong field is applied.
