Defect Core Structures in Twisted Nematic and Twisted Chiral Liquid Crystals
The defect structures of s = ±1/2 twist disclinations in twisted nematic and twisted chiral liquid crystals have been investigated within the Landau-de Gennes theory numerically. Our results show that there exists eigenvalue exchange across the defect core of both the two models. The defect core is essentially biaxial and never isotropic. The defect centre is uniaxial and is surrounded by a str...
متن کاملSpontaneously Twisted Nonchiral Nematic Liquid Crystals
Miroscopic theories of nematic liquid crystals allow us to calculate from a few molecular parameters a number of macroscopic and static properties, such as the equation of state, the short and long-range order parameters and the visco-elastic coefficients. An attempt to provide such a microscopic theory which, for the more common nematics, fits the experimental data for the elastic constants an...
متن کاملOn 3D non-Riemannian geometry of twisted nematic liquid crystals
A teleparallel geometrical description of the nematic phases of liquid crystals is proposed.In the case of the twisted geometry of nematics Cartan torsion is given by a spatial helical form which depends on the twist angle. Geodesics of a test particle around the teleparallel liquid crystal are given. PACS numbers : 0420,0450 Departamento de F́ısica Teórica Instituto de F́ısica UERJ Rua São Fco. ...
متن کاملPseudo-Casimir effect in untwisted chiral nematic liquid crystals.
We investigate theoretically the pseudo-Casimir force between parallel plates immersed in a chiral nematic liquid crystal. We focus on small-separation limit where the director configuration between the plates inducing strong homeotropic anchoring is uniform. We find that the force is attractive at separations smaller than the crossover distance and repulsive otherwise, and that it diverges log...
متن کاملThe Phase Transitions from Chiral Nematic toward Smectic Liquid Crystals
A Chen-Lubensky energy is used to investigate phase transitions from chiral nematic to smectic C* and smectic A* liquid crystal phases. We consider a liquid crystalline material Ω confined between two parallel plates, where the dimensions of Ω are assumed to be large relative both to the width of a smectic layer and the material’s chiral pitch. We take boundary conditions so that the smectic ph...
