抄録

We report pure noise-induced pattern formations in a homeotropically aligned nematic liquid crystal. Williams domains and stripe patterns are induced by colored and white noises, respectively, and the Fredericks transition is also found, which has no dependence on correlation time of the external noise. Furthermore, threshold behavior in the presence of a regular (sinusoidal) field superposed with the noise was investigated to understand the intrinsic role of the noise on the mechanisms driving noise-induced patterns and transitions.
