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.

Tristable Switching in Surface Stabilized Ferroelectric Liquid Crystals with a Large Spontaneous Polarization
TL;DR: In this paper, a new switching process was observed in surface stabilized ferroelectric liquid crystals, associated with a third stable state in addition to the well-known bistable states.
Journal ArticleDOI
Current topics in smectic liquid crystal research.
TL;DR: This Review discusses some of the topics of highest interest in current smectic liquid crystal research, and address application-relevant research (de Vries-type tilting transitions without defect generation and high-tilt antiferroelectric liquid crystals with perfect dark state) as well as more curiosity-driven research.

TL;DR: A class of fluid polar smectic liquid crystals in which local splay prevails in the form of periodic supermolecular-scale polarization modulation stripes coupled to layer undulation waves is reported.

Stability of Antiferroelectricity and Causes for its Appearance in SmCα* and SmCA* Phases of a Chiral Smectic Liquid Crystal, MHPOBC

TL;DR: In this article, two types of molecular interactions are proposed: the interaction between the spontaneous polarizations in the neighboring layers which is effective in SmCα*, and the pairing of transverse dipole moments responsible for the antiferroelectricity in SmCA*.
