20.500.12556/RUL-135428 Curvature potential unveiled topological defect attractors 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 of a curvature tensor field and a nematic tensor order parameter field. Extrinsic, intrinsic, and total curvature potentials are introduced using the parallel transport concept. These potentials reveal curvature seeded TD attractors. To test ground configurations, we used axially symmetric nematic films exhibiting spherical topology. topological defects nematic liquid crystals nematic shells geometric potentials curvature topološki defekti nematski tekoči kristali nematične lupine geometrijski potenciali ukrivljenost true false true Angleški jezik Slovenski jezik Članek v reviji 2022-03-14 11:04:57 2022-03-14 11:04:57 2022-09-14 04:13:16 0000-00-00 00:00:00 2021 0 0 16 str. iss. 5, art. 539 Vol. 11 May 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 548/549 2073-4352 10.3390/cryst11050539 63076611 RAZ_Mesarec_Luka_2021.pdf RAZ_Mesarec_Luka_2021.pdf 1 D37DF9243C3A40B2730421CDC25A798E 7f1bc5bc1fb91afc381ce63ca113bd2c8696dd5f03a5437497cce9f11aaa201a 808ef70b-a37e-11ec-8556-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=154494 https://www.mdpi.com/2073-4352/11/5/539 1 33bdb6b7-a37e-11ec-8556-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=154493 Fakulteta za elektrotehniko Zdravstvena fakulteta 0 0 0
