Macroscopic dynamics of chiral smectic C

2014 The hydrodynamic equations describing the macroscopic behaviour of chiral smectic C are presented. To derive these equations the nature of the spontaneously broken continuous symmetries is considered and their consequences for the hydrodynamics are pointed out. Similarities and differences to achiral smectic C and cholesteric liquid crystals are investigated in some detail. The influence a...

THE CONTINUUM THEORY FOR SMECTIC C* LIQUID CRYSTALS AND ITS APPLICATION TO REORIENTATION DYNAMICS By

We formulate the hydrodynamic theory of smectic C* liquid crystals and discuss its application. We follow the Ericksen-Leslie approach with the smectic C* Chen-Lubensky free energy. Based on the flow model that we derived from the nonlinear continuum model of smectic C* liquid crystals, we obtained dynamical properties of the model in homeotropic geometry, where the smectic layers are parallel ...

Hydrodynamics 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 ...

Electrohydrodynamic Instabilities in the Liquid Crystalline Phases with Smectic Ordering

An investigation has been made of the frequency characteristics of the threshold voltage of domain instabilities induced by an electric field in both homogeneously and homeotropically oriented liquid crystal layers. The mesogens had the nematic and smectic A phases and their anisotropy of the electrical conductivity changed its sign at the critical temperature somewhat above the nematic-smectic...

Smectic phases in ionic liquid crystals

Ionic liquid crystals (ILCs) are anisotropic mesogenic molecules which carry charges and therefore combine properties of liquid crystals, e.g. the formation of mesophases, and of ionic liquids, such as low melting temperatures and tiny triple-point pressures. Previous density functional calculations have revealed that the phase behavior of ILCs is strongly affected by their molecular properties...
