Izvirni znanstveni članek
Oznake: fizika;tekoči kristali;nematični kristali;nematični defekti;strukturni prehodi;physics;liquid crystals;nematic crystals;nematic defects;structural transitions;
By use of the Landau-de Gennes phenomenological theory, we study the texture of a nematic liquid crystal confined within a hybrid cell. Precisely, we consider cylindrically symmetric solutions containing topological defects dictated by appropriate boundary conditions. We focus our attention on cells ...

Oznake: fizika;tekoči kristali;nematični kristali;linijski defekti;površinske strukture;physics;liquid crystals;nematic crystals;line defects;surface phenomena;
Using the Landau-de Gennes phenomenological approach, we study the fine biaxial core structure of a boojum residing on the surface of a nematic liquid crystal phase. The core is formed by a negatively uniaxial finger, surrounded by a shell with maximal biaxiality. The characteristic finger's length ...

Curvature potential unveiled topological defect attractors
Luka Mesarec, Aleš Iglič, Veronika Kralj-Iglič, Wojciech Góźdź, Epifanio G. Virga, Samo Kralj
Izvirni znanstveni članek
Oznake: topološki defekti;nematski tekoči kristali;nematične lupine;geometrijski potenciali;ukrivljenost;topological defects;nematic liquid crystals;nematic shells;curvature;
We consider the theoretical and positional assembling of topological defects (TDs) in effectively two-dimensional nematic liquid crystal films. We use a phenomenological Helfrich–Landau–de Gennes-type mesoscopic model in which geometric shapes and nematic orientational order are expressed in terms o ...
