摘要：

The time decay of correlation for Brownian motion in a one-dimensional periodic potential and for large viscosity is studied analytically in an asymptotic method. The result is related to the dynamics of an overdamped sine-Gordon chain. The relevance of our finding to the superionic conduction phenomena is discussed. © 1979.
