Abstract:
Electroconvecting patterns have been observed for nematic liquid crystals with homeotropic alignment and with strongly positive dielectric anisotropy and negative anisotropy of the conductivity. In the (U, q) space, three distinct morphologies, rolls and squares, soft squares and hard squares has been observed. We perform a linear and nonlinear analysis of the full nematohydrodynamic equations and carry out simulations of a suitably constructed Lorenz model.
