Response of dissipative structures to noise using electroconvectionin nematic liquid crystals

研究了电对流耗散结构对外部噪声的响应。由于ECs的内在机制，其噪声诱发阈值和波长完全不同。响应很大程度上取决于噪声的特性（例如，白色或彩色噪声）。特别是，我们的波长变化的结果（高频区域的chevrons）对利用ECs制造调制聚合物表面是非常有用的。

We investigated the response of dissipative structures of electroconvections (ECs) to external noise. Due to the intrinsic mechanisms of ECs, noise-induced thresholds and wavelengths were completely different from one another. The response strongly depended on the characteristic of noise (e.g., white or colorednoises). In particular, our results of the wavelength variations (of chevrons in high frequency region) are quite useful for fabricating modulated polymer surfaces by means of ECs.
