Difuzijsko omejena agregacija
Saša Harkai, Samo Kralj
Diplomsko delo
Oznake: diplomski seminarji;fizika;model brez mreže;Brownovo gibanje;fraktal;fraktalna dimenzija;
V diplomskem seminarju obravnavamo difuzijsko omejeno agregacijo. Predstavimo matematični model, s katerim generiramo agregate, ki jih karakteriziramo s parametri, kot so število delcev, temperatura, velikost delcev, razdalja med robom in agregatom ter jakost zunanjega polja. Prikažemo vpliv različn ...

Rekonfigurabilne mreže nematskih topoloških defektov
Saša Harkai, Samo Kralj
Doktorska disertacija
Oznake: tekoči kristali;nematiki;topološki defekti;
V delu obravnavamo kompleksne strukture linijskih defektov v enoosni nematski fazi, ograjeni v planparalelno geometrijo, in različne načine njihovega prevezovanja. Nematske strukture opisujemo na mezoskopski skali s tenzorskim nematskim ureditvenim parametrom. Ravnovesna stanja določimo z numerično ...

Finite-size effects in soft matter under an electric field stimulus
Saša Harkai, Samo Kralj, Victor Teboul
Magistrsko delo
Oznake: master theses;finite size;glass transition;diffusion constant;dynamic heterogeneity;electric field;
In this thesis, we study the effect of an external electric field on the properties of glass forming liquids. We present the properties relevant and important for understanding the phenomenon, such as the transition temperature and the temperature dependence of viscosity. We create a numerical model ...

Reconfiguration of nematic disclinations in plane-parallel confinements
Saša Harkai, Charles Rosenblatt, Samo Kralj
Izvirni znanstveni članek
Oznake: tekoči kristali;topologija;topološki defekti;disklinacije;rekonfiguracije;ne zaključna dela;liquid crystals;topological defects;disclinations;reconfiguration;
We study numerically the reconfiguration process of colliding |m|=1/2 strength disclinations in an achiral nematic liquid crystal (NLC). A Landau–de Gennes approach in terms of tensor nematic-order parameters is used. Initially, different pairs {m1,m2} of parallel wedge disclination lines connecting ...

Reconfiguration of nematic dislocations
Saša Harkai, Mitja Kralj, Samo Kralj

Basic natural entities seems to be physical fields. From this perspective elementary particles should correspond to robust localized field configurations. Most probable candidates for such configurations are topological defects. They are topologically protected and they exhibit robust body-like feat ...

Electric field driven reconfigurable multistable topological defect patterns
Saša Harkai, Bryce S. Murray, Charles Rosenblatt, Samo Kralj
Izvirni znanstveni članek
Oznake: line defects;topological defects;nematic liquid crystals;electric field;atomic force microscopy;numerical techniques;polarized optical microscopy;
Topological defects appear in symmetry breaking phase transitions and are ubiquitous throughout Nature. As an ideal testbed for their study, defect configurations in nematic liquid crystals (NLCs) could be exploited in a rich variety of technological applications. Here we report on robust theoretica ...
