Light Waves

Evolution of four waves propagating forward in nematic liquid crystal is studied using Hamiltonian representation of initial equations describing the process. Here we extend theory of the four-wave mixing on thermal nonlinearity of nematic liquid crystal. All types of analytical solutions are found for these equations. The possibilities of observing of optical switching in this mixing are discussed.

Flow Case

AbstractHere we investigate the kinematic transports of the defects in the nematic liquid crystal system by numerical experiments. The model is a shear flow case of the viscoelastic continuummodel simplified fromthe Ericksen-Leslie system. The numerical experiments are carried out by using a difference method. Based on these numerical experiments we find some interesting and important relationships between the kinematic transports and the characteristics of the flow. We present the development and interaction of the defects. These results are partly consistent with the observation from the experiments. Thus this scheme illustrates, to some extent, the kinematic effects of the defects.
