Abstract:Tekoči kristali omogočajo številne vizualizacije geometrijskih zakonitosti. V magistrski nalogi bomo s pomočjo dvodimenzionalnega Landau-de Gennes tenzorskega formalizma proučevali topološke defekte v nematičnih lupinah. Slednje predstavljajo tanko plast nematičnih tekočih kristalov, nanesenih na površino koloidnih delcev. Zapisali bomo funkcional proste energije in za poseben primer osno-simetričnih lupin izpeljali Euler-Lagrangeovi enačbi, ki jih bomo reševali numerično. Raziskali bomo, kako različni seti elastičnih konstant vplivajo na konfiguracije topoloških defektov pri različnih elipsoidih. Poudarek bo na vplivu tako imenovanega Napolijevega polja.

Title:Topological defects in nematic shells
Abstract:Liquid crystals offer several visual representations of the underlining geometric rules. In thesis, we study topological defects in nematic shells, within a two-dimensional Landau-de Gennes tensorial formalism. Nematic shells are colloidal particles, coated with a thin sheet of nematic liquid crystal. For a special case of axis-symmetric shells, we derive the Euler-Lagrange equations for the free-energy functional. We solve Euler-Lagrange equation numerically. We present, how different combinations of elastic constants, influences on topological defect configurations for different ellipsoids. Our main focus is the influence of the term proposed by Napoli.
Keywords:Soft Matter, Liquid Crystals, Topological Defects, Nematic Shells, Colloidal Particles, Napoli Field
