Light Scattering Properties of Nematic Liquid Crystals
The fundamental properties of simple liquid crystal systems will be reviewed. In particular the elastic and hydrodynamic properties will be discussed in terms of a new, simple, rigorous theory that is more general than previous theories. The light scattering properties observed by Chatelain, and more recently by the Orsay group, follows simply from this theory. Basically this differs from previous theories in that the hydrodynamics and elastic properties are treated purely in terms of the usual conserved quantities (momentum, energy and mass) without the need to postulate a separate equation for the director. The introduction of this separate equation, that has been common, requires assumptions that are not usually necessary in rigorous hydrodynamics and that are not in fact needed to explain the existing observations on liquid crystals.
