TLDR
The role of the phase in the second order smectic A↔ nematic transition is similar to the role of phase functions in superconductors as mentioned in this paper, where twist and bend distortions correspond to magnetic fields.About:

Polymer-stabilized liquid crystal blue phases
Hirotsugu Kikuchi,Hirotsugu Kikuchi,Masayuki Yokota,Yoshiaki Hisakado,Huai Yang,Tisato Kajiyama +5 more
TL;DR: This work shows the stabilization of blue phases over a temperature range of more than 60 K including room temperature (260–326 K), and demonstrates an electro-optical switching with a response time of the order of 10−4 s for the stabilized blue phases at room temperature.

Physics of liquid crystals
TL;DR: In this article, the physical properties of nematic, cholesteric, and smectic liquid crystals are discussed and a wide variety of phenomena in liquid crystals, including elastic distortions, disclinations, flow properties, fluctuations, light scattering, wave propagation, nuclear magnetic resonance, effects of magnetic and electric fields, electrohydrodynamics, and optical properties.

Surface effects and anchoring in liquid crystals
TL;DR: In this paper, a review focusing on nematic liquid crystals is presented, where three main kinds of effects can be distinguished: the perturbation of the liquid crystalline structure close to the surface, the bulk liquid crystal structure is recovered with an orientation which is fixed by the surface and critical adsorption or wetting can occur at surfaces.

Ferroelectric Liquid Crystals; A Review
TL;DR: The development and current state of knowledge of ferroelectric liquid crystals are reviewed in this paper, where the Curie point and effects visible in freely suspended films are compared with crystalline ferroelectrics.
Journal ArticleDOI
Characterization of a new helical smectic liquid crystal
TL;DR: The smectic-A* phase as discussed by the authors is the first liquid crystal to exhibit optical activity by virtue of a helical arrangement of its constituent molecules, where lath-like molecules are arranged in layers with their long axes on average normal to the layer planes.

X-ray Photographic Studies of Liquid Crystals I. A Cybotactic Nematic Phase
TL;DR: In this paper, it was shown that the X-ray diffraction patterns of the nematic phase of bis-(4′-n-octyloxybenzal)-2-chloro-1, 4-phenylenediamine show major maxima at two diffraction angles.
Journal ArticleDOI
Evidence for the Existence of More Than One Type of Nematic Phase
TL;DR: In this article, it was suggested that there may be three types of nematic phases: skewed cybotactic, normal and classical nematic phase, in which no regular arrangement between neighboring molecules exists.

X-Ray Photographic Studies of Liquid Crystals: II. Apparent Molecular Length and Thickness in Three Phases of Ethyl-p-ethoxybenzal-p-aminobenzoate
TL;DR: In this article, a general theory was developed for the relation between the molecular length and the position of a diffraction maximum found at diffraction angles of the order of 4°, for nematic and isotropic phases containing elongated molecules.
