Effect of Polarization Field on Elastic Deformation in a 180° Twisted Sample of Chiral Smectic C Liquid Crystal

Abstract

The effect of the polarization field on the elastic deformation in chiral smectic C liquid crystals is presented. In this work, a 180° twisted sample of chiral smectic C liquid crystal is concerned and the polarization field induced by the spontaneous polarization is consistently taken into account as well as an externally applied electric field. It is found that the effect of the polarization field must not be neglected to study such deformation of chiral smectic C liquid crystals when there exists the polarization charge induced by the spontaneous polarization.
