Abstract
The coupling between the motion of ionic impurities and the bend-type director distortion in a ferroelectric liquid crystal is examined theoretically. We calculate the relaxation rate of the (fast) director mode to lowest order in the ion concentration. Moreover, we calculate the ratio Kfast(=0)/K(=0), where K() is the amplitude of the temporal autocorrelation function for director fluctuations, is the correlation time, and Kfast() is the corresponding value for the quickly decaying component of this quantity. The ratio, which can be measured in a light-scattering experiment, yields the inverse Debye-Hückel screening length.
