Title: Dynamic critical behavior of the Landau-Peierls fluctuations: Scaling form of the dynamic density autocorrelation function for smectic-A films
Abstract: In this paper, we study the dynamic density autocorrelation function for smectic-A films in the layer sliding geometry. We first a scaling form for G, and then we shaw that our postulated form holds by comparing the scaling predictions with detailed calculations. We find some deviations from the scaling form for very thin films. For thick films, we find a region of a behavior, where the dynamics is characterized by the same critical exponent eta, which was originally introduced by Caille R. Acad. Sci. Ser. B 274 891 (1972)]. In the limit of very large perpendicular to the layer normal, or in the limit of very long we find that the decay of G is governed by the surface exponent
