Charged ±2π-twist Disclinations in Ferroelectric Liquid Crystals

  • Published:
Czechoslovak Journal of Physics Aims and scope

Abstract

The electrostatic charge of (±2π)-twist disclinations in ferroelectric chiral smectic C liquid crystals is introduced as an approximation in order to simplify the evaluation of the electrostatic self-energy of disclination. As an example, electrostatic charges of (±2π)-twist disclinations in an infinite sample are evaluated. Screening effects of free charges in a material and of the ferroelectric structure surrounding the disclination are taken into account by introducing a phenomenological depolarization factor.
