Abstract
A homeotropic nematic liquid crystal was exposed to low frequency oscillatory shear. In the presence of rectilinear shear a stationary roll pattern was found above a critical amplitude. In case of elliptical excitation a spatially nonuniform slow rotation of the director was observed, which lead to the propagation of the so-called phase waves in two different systems: in a two-phase system and in a homeotropic nematic layer in the presence of a destabilizing external electric filed. Phase waves also have been observed in the ultrasonic frequency range at much smaller shear amplitudes.
