Macroscopic dynamics of polar nematic liquid crystals.
We present the macroscopic equations for polar nematic liquid crystals. We consider the case where one has both, the usual nematic director, n[over ] , characterizing quadrupolar order as well as the macroscopic polarization, P , representing polar order, but where their directions coincide and are rigidly coupled. In this case one has to choose P as the independent macroscopic variable. Such e...
متن کاملCoarsening dynamics of biaxial nematic liquid crystals.
We study the coarsening dynamics of two- and three-dimensional biaxial nematic liquid crystals, using Langevin dynamics. Unlike previous work, we use a model with no a priori relationship among the three elastic constants associated with director deformations. Biaxial nematics possess four topologically distinct classes of defects, three of which have half-integer charge, while the fourth, whic...
متن کاملHydrodynamics and Electrohydrodynamics of Liquid Crystals
We present the hydrodynamic and electrohydrodynamic equations for uni-axial nematic liquid crystals and explain their derivation in detail. To derive hydrodynamic equations, which are valid for suuciently small frequencies in the limit of long wavelengths, one identiies rst the hydrodynamic variables , which come in two groups: quantities obeying conservation laws and variables associated with ...
متن کاملPattern-induced anchoring transitions in nematic liquid crystals.
In this paper we revisit the problem of a nematic liquid crystal in contact with patterned substrates. The substrate is modelled as a periodic array of parallel infinite grooves of well-defined cross-section sculpted on a chemically homogeneous substrate which favours local homeotropic anchoring of the nematic. We consider three cases: a sawtooth, a crenellated and a sinusoidal substrate. We an...
متن کاملFlexoelectricity and pattern formation in nematic liquid crystals.
We present in this paper a detailed analysis of the flexoelectric instability of a planar nematic layer in the presence of an alternating electric field (frequency ω), which leads to stripe patterns (flexodomains) in the plane of the layer. This equilibrium transition is governed by the free energy of the nematic, which describes the elasticity with respect to the orientational degrees of freed...
