- 論文の詳細を見る
New experimental aspects of multiplicative noise effects on the onset of ac-driven electroconvection in nematic liquid crystals are presented. In the superposition of a stochastic field with a deterministic one, the variation in the threshold voltage V_c (of the deterministic one) was investigated as a function of the intensity (V_N), cutoff frequency (f_c), and correlation time(τ_N)of the stochastic noise. In particular, it is observed that the noise effects vanish for certain stochastic and deterministic conditions.
