Ferroelectric Liquid Crystals
TLDR
The main advances in the field of bulk ferroelectric liquid crystals since 1984 are reviewed in this paper, where the molecular tilt and in-plane spontaneous polarization are not strictly proportional to each other as assumed before.Abstract:
The main advances in the field of bulk ferroelectric liquid crystals since 1984 are reviewed. Recent experiments have shown that the molecular tilt and the in-plane spontaneous polarization are not strictly proportional to each other as assumed before. Microscopic experiments such as NMR and NQR have further allowed for a determination of the basic order parameters as a function of the nuclear position along the molecule without unwinding the chiral helix.read more

Thermodynamic Model of Ferroelectric Chiral Smectic C* Liquid Crystals
TL;DR: A thermodynamic model of the ferroelectric SmC* phase, based on an extended Landau expansion of the free energy density, is presented in this article, where the signs of the parameters entering the model are depending on whether the pitch of the helix is right-handed or left-handed and whether the compound is of the (+) or (-) type in regard to the sign of the polarization.

Goldstone mode and soft mode at the smectic-A-smectic-C phase transition studied by dielectric relaxation.
TL;DR: By reasonable assumptions, it is shown that a simple relation between the Goldstone-mode contribution to the dielectric susceptibility and the polarization and pitch can be derived, and a small peak of theDielectric strength is predicted to exist at ${T}_{c}$.
