New structure induced by elastic anisotropy in cylindrical nematic liquid crystal
Journal Title: JOURNAL OF ADVANCES IN PHYSICS - Year 0, Vol 13, Issue 2
Abstract
Basing on Landaude Gennes theory, this study investigated the chiral configurations of nematic liquid crystals confined to cylindrical capillaries with homeotropic anchoring on the cylinder walls. When the elastic anisotropy (L2/L1) is large enough, a new structure results from the convergence of two opposite escape directions of the heterochiral twist and escape radial (TER) configurations. The new defect presents when L2/L17 and disappears when L2/L1<7. The new structure possesses a heterochiral hyperbolic defect at the center and two homochiral radial defects on both sides. The two radial defects show different chiralities.
