Flexoelectric surface switching of bistable nematic devices
Physical Review Letters 87:27 I (2001) 2755051-2755054
Abstract:
A new method of dynamically controlling the boundary conditions of a nematic liquid crystals was studied using surface flexoelectric effect. Switching between the states occurs when the movement of the surface directors rotates those in the bulk, which are then able to create or annihilate defects. The results showed that the driving force that causes the switching is a surface flexoelectric effect.Probing the strong boundary shape dependence of the Casimir force.

Abstract:
We study the geometry dependence of the Casimir energy for deformed metal plates by a path integral quantization of the electromagnetic field. For the first time, we give a complete analytical result for the deformation induced change in Casimir energy delta E in an experimentally testable, nontrivial geometry, consisting of a flat and a corrugated plate. Our results show an interesting crossover for delta E as a function of the ratio of the mean plate distance H, to the corrugation length lambda: For lambda<Quantum criticalities in a two-leg antiferromagnetic S=1/2 ladder induced by a staggered magnetic field
