3B12 高速ビデオカメラによる液晶の配向ゆらぎの直接観測III

抄録

In the previous report we have shown that the orientation fluctuation in a nematic liquid crystal can be observed with a high-speed video camera and the time correlation function in the Fourier space obeys the exponential law. However, the wavenumber dependence of the relaxation frequency could not be explained by a simple theory. In this paper we will propose a theory and analyze the experimental data.
