Analysis of Nonlocal Electrostatic Effects in Chiral Smectic C Liquid Crystals

Phase behavior in the reentrant-nematic region of chiral frustrated smectic liquid crystals

A high-resolution ac calorimetric study has been carried out on two homologous polar liquid crystals with aromatic cores containing three phenyl groups and a flexible chiral linking group. The expected smectic polymorphism occurs, and there are several prominent thermal features in the nematic range between smecticAd and smectic-C̃ phases. It is suggested on the basis of characteristic thermal s...

Macroscopic dynamics of chiral smectic C

2014 The hydrodynamic equations describing the macroscopic behaviour of chiral smectic C are presented. To derive these equations the nature of the spontaneously broken continuous symmetries is considered and their consequences for the hydrodynamics are pointed out. Similarities and differences to achiral smectic C and cholesteric liquid crystals are investigated in some detail. The influence a...

Dynamic amplification of light signals in photorefractive ferroelectric liquid crystalline mixtures.

The photorefractive effect in photoconductive ferroelectric liquid crystals that contain photoconductive chiral compounds was investigated. Terthiophene compounds with chiral structures were chosen as the photoconductive chiral compounds, and they were mixed with an achiral smectic C liquid crystal. The mixtures exhibit the ferroelectric chiral smectic C phase. The photorefractivity of the mixt...

Chiral Smectic C Liquid Crystal, Thick Sample Textures

The texture of ferroelectric chiral smectic liquid crystal confined between two aligning plates is studied in the case of thick samples i-esamples whose thickness is higher than the helical pitch. The helical texture with periodic unwinding discfination lines
