Journal ArticleDOI
Molecular dynamics study of nematic structures confined to a cylindrical cavity
TL;DR: In this article, a modified induced-dipolem type coupling was used to simulate microscopic liquid crystal structures confined to a submicron cylindrical cavity and stability regions of characteristic nematic structures were determined as functions of the cylinder radius, homeotropic anchoring strength, and degree of the interaction anisotropy.
Journal ArticleDOI
Annihilation of nematic point defects: Pre-collision and post-collision evolution
TL;DR: The annihilation of the nematic hedgehog and anti-hedgehog within an infinite cylinder of radius R is studied using the semi-microscopic lattice-type model and Brownian molecular dynamics and results agree qualitatively with the existing experimental observations and also continuum-type simulations.
Journal ArticleDOI
Molecular dynamics study of the isotropic-nematic quench.
Z. Bradač,Samo Kralj,S. Zumer +2 more
TL;DR: Effects of cylindrical and spherical confinement on the kinetics of the isotropic-nematic quench is studied numerically and the nematic liquid crystal structure was modeled by a modified induced-dipole--induced-Dipole interaction.
Journal ArticleDOI
Early stage domain coarsening of the isotropic-nematic phase transition.
TL;DR: It is shown that soon after the transition bimodal distribution of domains appears, where the shorter branch gradually vanishes, and the behavior of the system is in accordance with predictions of the Kibble-Zurek mechanism.
Journal ArticleDOI
The influence of nanoparticles on the phase and structural ordering for nematic liquid crystals
TL;DR: In this paper, the influence of nanoparticles (NPs) on liquid crystal (LC) ordering was studied. But the authors focused on the phase behavior of the NPs and not the structural ordering of the liquid crystal.
