TLDR
In this article, the Dupin cyclides were simulated in one small region of the sample, and the results showed that the polygonal texture was polygonally smooth. But they did not report experimental observations with optical microscopy of the usual "polygonal" texture.Abstract:
We report experimental observations with optical microscopy of the usual so-called polygonal texture. We have made simulations of the Dupin cyclides in one small region of the sample.read more

Microlentilles et micro-miroirs en cristal liquide cholestérique
TL;DR: In this article, the texture polygonale cholesterique of the carapace of Chrysina gloriosa, analogue biologique, is investigated. But the main purpose of the paper is to decrire et comprendre l'interaction de la lumiere avec different types of structures helicoidales non-monotones elaborees dans cette these - films cholesteriques synthetiques (monocomposant ou hybrides i.e. dopes en nanoparticules d'or) - or d

TL;DR: A numerical simulation with Python software is proposed to reproduce this tiling of ellipses as well as the shape of the smectic layers taking the well-known shape of Dupin cyclides within this particular bâtonnet area.

TL;DR: In this article, the authors explain how low power consumer displays work from an optical viewpoint, providing an examination of aspects of the optics of liquid crystals, as well as exploiting defect structures and non-linear optics.

Smectic Liquid Crystal Defects for Self-Assembling of Building Blocks and Their Lithographic Applications
TL;DR: Recently, it has been reported that liquid crystal (LC) defects can be used to create highly periodic templates by controlling the surface anchoring and the elastic properties of LC molecules as discussed by the authors, which takes advantage of the ability to achieve fast stabilization of molecular ordering and structure due to the reversible and non-covalent interactions of the LC molecules.

TL;DR: This study unequivocally shows that the arrangement of FCDs is strongly influenced by the height and shape of the pillars, a feature that promotes both a variety of nontrivial self-assembled lattice types and the attraction of F CD centers to pillar edges, especially at regions of high curvature.

Grain boundaries and the law of corresponding cones in smectics

TL;DR: In this article, it was shown that a tilt grain boundary (TiGB) of vanishing disorientation made of toric focal conic domains has a vanishing energy, yielding metastable local equilibrium, which explains why FCD tilings show macroscopic zones not filled with FCDs.
