Nonlinear bending of molecular films by polarized light
Yu. B. Gaididei, A. P. Krekhov, H. Buettner
A theory of photoinduced directed bending of non-crystalline molecular films is presented. Our approach is based on elastic deformation of the film due to interaction between molec…
Flexoelectricity and competition of time scales in electroconvection
Tibor Toth-Katona, Nandor Eber, Agnes Buka +1
Novel behavior in electroconvection (EC) has been detected in nematic liquid crystals (NLCs) under the condition of comparable timescales of the director relaxation and the period…
Dynamics of cholesteric structures in an electric field
O. S. Tarasov, A. P. Krekhov, L. Kramer
Motivated by Lehmann-like rotation phenomena in cholesteric drops we study the transverse drift of two types of cholesteric fingers, which form rotating spirals in thin layers of c…
Transition to spatially periodic patterns in nematics under oscillatory shear flow: linear analysis
O. S. Tarasov, A. P. Krekhov, L. Kramer
We consider the orientational instabilities, both homogeneous and spatially periodic, developing in a nematic liquid crystal under rectilinear oscillatory Couette flow for director…
Flexoelectric Instability in Nematic Liquid Crystal between Coaxial Cylinders
I. V. Kotov, M. V. Khazimullin, A. P. Krekhov
The stability of the equilibrium configurations of a nematic liquid crystal confined between two coaxial cylinders is analysed when a radial electric field is applied and the flexo…
Dynamics of Nematic Liquid Crystal under Oscillatory Flow: Influence of Surface Viscosity
I. Sh. Nasibullayev, A. P. Krekhov, M. V. Khazimullin
We analyse the influence of a surface viscosity on the orientational dynamics of a nematic liquid crystal subjected to an oscillatory Couette flow. Approximate analytical solutions…
