Flexoelectric Instability in Nematic Liquid Crystal between Coaxial Cylinders
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 flexoelectric effect is taken into account.

| Zusammenfassung: | 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 flexoelectric effect is taken into account. The threshold
for perturbations depending only on the radius r in the cylindrical coordinate
system and strong boundary conditions is studied. A new type of orientational
transition caused by pure flexoelectric effect is found. |
