Stability and metastability in nematic glasses: a computational study
Stability and metastability in nematic glasses: a computational study
The influence of randomly distributed impurities on liquid crystal (LC) orientational ordering is studied using a simple Lebwohl-Lasher type lattice model in two (d=2) and three (d=3) dimensions. The impurities of concentration p impose a random anisotropy field-type of disorder of strength w to the LC nematic phase. Orientational correlations can be well presented by a single coherence length for a weak enough w. We show that the Imry-Ma scaling prediction w holds true if the LC configuration is initially quenched from the isotropic phase. For other initial configurations the scaling is in general not obeyed

Abstract
The influence of randomly distributed impurities on liquid crystal (LC) orientational ordering is studied using a simple Lebwohl-Lasher type lattice model in two (d=2) and three (d=3) dimensions. The impurities of concentration p impose a random anisotropy field-type of disorder of strength w to the LC nematic phase. Orientational correlations can be well presented by a single coherence length for a weak enough w. We show that the Imry-Ma scaling prediction w holds true if the LC configuration is initially quenched from the isotropic phase. For other initial configurations the scaling is in general not obeyed
