Theory of polarizable liquid crystals: Optical birefringence
polarizable liquid crystals Optical birefringence
2014/9/24
The theory of polarizable anisotropic fluids is developed on the basis of a model fluid consisting of anisotropic Drude oscillators with embedded permanent dipoles. A matrix theory is developed. The d...
The helical phase of chiral nematic liquid crystals as the Bianchi VII(0) group manifold
The helical phase chiral nematic liquid crystals the Bianchi VII(0) group manifold
2011/9/13
We show that the optical structure of the helical phase of a chiral nematic is naturally associated with the Bianchi V II0 group manifold, of which we give a full account. The Joets-Ribotta metric gov...

A blow-up criterion for the compressible liquid crystals system
the compressible liquid crystals system math
2010/11/23
In this paper, we establish a blow-up criterion for the compressible liquid crystals equations in terms of the gradient of the velocity only, similar to the Beale-Kato-Majda criterion \cite{majda} fo...
Nonlinear thermotropic and thermo-optical behaviour of planar oriented textures in nematic liquid crystals at phase transitions
Liquid crystals Nematic Phase transitions Texture Optical transmission Optical birefringence
2010/6/30
Thermotropic, thermo-morphologic and thermo-optical properties of the planar oriented nematic liquid crystals have been investigated for large temperature interval and especially for the direct nemati...
Modelling of nematic liquid crystals in electromagnetic fields
Nematics degree of orientation evolution equation
2010/9/27
The paper elaborates a dynamic scheme which accounts for the evolution of nematic liquid crystals. The liquid crystal is allowed to be compressible and subject to the action of mechanical and electrom...
