  • Title: Competition between electroconvection and Fréedericksz distortions in nematic liquid crystals with slightly positive dielectric anisotropy.
    Author: Dressel B, Pesch W.
    Journal: Phys Rev E Stat Nonlin Soft Matter Phys; 2003 Mar; 67(3 Pt 1):031707. PubMed ID: 12689088.
    Abstract:
    Planar electroconvection in nematic liquid crystals with positive dielectric anisotropy is theoretically studied in the nonlinear regime. The system is characterized by a competition between the nonequilibrium electroconvection instability and the equilibrium Fréedericksz distortions. Near a resulting multicritical bifurcation point a splay-roll instability and a bistability between the convective and the homogeneous states occur.
