- Abstract
On the basis of the nonequilibrium hydrodynamics of a cholesteric liquid crystal (CLC), the properties of acoustic domains arising in a CLC layer under a normally incident ultrasonic wave are considered. The geometry and size of domains and the degree of deformation of the CLC structure are analyzed by the perturbation method for sound intensities exceeding the threshold value. Scaling dependences of the domain size and the deformation amplitude on the intensity of external action and the preliminary tension of the layer are plotted. It is shown that, as the effect advances beyond the threshold, the size of domains decreases.
