Defect controlled dynamics of nematic liquids

摘要: Abstract The long time dynamical response of a nematic liquid exhibiting banded textures (inversion walls) during the twist Freedericksz transition is presented. A model approach to equilibrium through defect interaction and resulting dissolution linear stability analysis shows that splay-bend inversion wall defects are unstable two dimensional infinitesimal perturbations. segment collapse with production disclination line pair given. energy-momentum tensor gives force between walls lines. perturbation evolution director field in closed form.
