Point defects in nematics, also called hedgehogs, are topological entities that have no
equivalent in ordered atomic solids, despite the homonymy. They have been the subject of …

The textures exhibited by nematic liquid crystals confined to cylindrical capillaries under
homeotropic anchoring have been studied for nearly thirty years. One of the reasons behind …

The annihilation of the nematic hedgehog and anti-hedgehog within an infinite cylinder of
radius R is studied. The semi-microscopic lattice-type model and Brownian molecular …

Nematic liquid crystals confined in a cylindrical capillary and subjected to strong
homeotropic anchoring conditions is a long-studied fundamental problem that uniquely …

Density of states Monte Carlo simulations have been performed to study the isotropic–
nematic (IN) transition of the Lebwohl–Lasher model for liquid crystals. The IN transition …

A spin dynamics algorithm, combining checkerboard updating and a rotation algorithm
based on the local second-rank ordering field, is developed for the Lebwohl-Lasher model …

We study Bloch walls defects formed by quenching nematic thin films from planar anchoring
to homeotropic anchoring through a temperature-driven anchoring transition. The direct or …

V doktorski disertaciji preučujemo vpliv defektov in nereda, ki ga v opazovani tekoče-
kristalni sistem vnesemo z ograjujočimi površinami in dodanimi primesmi. Pri tem se …

The annihilation of defect is studied theoretically in liquid crystals (LCs). We consider the
annihilation of point disclinations in nematic and line edge dislocations in smectic A LC …
