Phase Noise Can Induce Stochastic Resonance?
Search this article
Abstract
We investigated stochastic resonance (SR) of ac-driven electroconvection (EC) in nematic liquid crystals by employing the phase noise of the ac field. The phase noise smoothly varies the threshold of EC, as the amplitude noise does it. Surprisingly, a kind of phase stochastic resonance (PSR) is discovered in appropriately colored phase noises; thus, it provides nonmonotonic behavior of the threshold in which a peak of the pattern amplitude of EC is found as a function of the phase noise intensity. The colored and white phase noises are discussed for understanding the PSR.
