โœฆ Synopsis

The linearized Ericksen-Leslie differential equations, which couple fluid motion and director reorientation to each other, are reduced to a set of time varying differential equations for two pulsed optical waves incident at an angle upon a homeotropically orientated liquid-crystal cell. The differential equations are solved by a numerical method. The fluid velocity and the director angle are plotted as a function of space and time. It is shown that the reaction of fluid motion upon director reorientation is small.

The difference between liquidcrystal and gas-phase values for the nuclear quadrupole coupling constant in Dz and HD is used to obtain the mean electric field gradient in various liquid crystals. Order parameters for small molecules dissolved in liquid crystals are calculated assuming that the orient

We report the results of self-diffraction measurements in nematic liquid crystal films under the combined action of an applied DC electric field and an impinging optical field. The presence of self-diffraction in a two-wave-mixing experiment with low-power laser light is proof that the material is c
