چکیده

The static properties of nematic liquid crystals are summarized. The mean field potential emerging from the static distribution function has been used to the hydrodynamic theory. Rotational viscosity coefficients have been investigated. The Parodi relation has been shown to be completely satisfied. Static and hydrodynamic properties have been predicted on the basis of one intermolecular potential.

Recent developments of analysis for hydrodynamic flow of nematic liquid crystals.

The study of hydrodynamics of liquid crystals leads to many fascinating mathematical problems, which has prompted various interesting works recently. This article reviews the static Oseen-Frank theory and surveys some recent progress on the existence, regularity, uniqueness and large time asymptotic of the hydrodynamic flow of nematic liquid crystals. We will also propose a few interesting ques...

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 ...

Investigation into the temperature dependence of isotropic- nematic phase transition of Gay- Berne liquid crystals

Density functional approach was used to study the isotropic- nematic (I-N) transition and calculate the values of freezing parameters of the Gay- Berne liquid crystal model. New direct and pair correlation functions of a molecular fluid with Gay- Berne pair potential were used. These new functions were used in density functional theory as input to calculate the isotropic- nematic transition den...

Electroconvection in Nematic Liquid Crystals: Comparison between Experimental Results and the Hydrodynamic Model

We describe experimental observations illustrating the extraordinary sensitivity of pattern formation in electroconvection in nematic liquid crystals to changes in magnitude and sign of dynamic transport coe cients triggered by weak uctuations from a lower temperature nematic-smectic A phase transition. These results are compared to predictions of a hydrodynamic model (HM). We nd two patterns a...

Static and dynamic behavior of a nematic liquid crystal in a magnetic field. Part II : Dynamics

2014 The dynamics of the distortion of a well-oriented nematic liquid crystal film in a perpendicular field around the Freedericks critical field value is studied both theoretically and experimentally. The experimental thermal and optical techniques have already been used for the description of the equilibrium properties of the transition. Their use for the measurement of transition rates leads...
