Dynamics in spatially confined dipolar liquids — •Sabine H.L. Klapp — Stranski-Laboratorium für Physikalische und Theoretische Chemie, Sekr. TC 7, Fakultät II, Technische Universität Berlin, Straße des 17 Juni 124, 10623 Berlin, Germany

Based on Molecular Dynamics simulations we investigate the interplay between static and dynamic properties of confined films of simple dipolar fluids, which can be considered as model systems for confined polar liquids or ferrocolloid films. Previous Monte Carlo studies (1,2) on such systems have shown that the specific properties of dipolar interactions, combined with the presence of confining walls, yields interesting orientational effects such as wall–induced chain formation in the contact layer and spontaneous global polarization at pressures lower than in the bulk. Here we discuss the implications of these features on translational and rotational time correlation functions and on resulting transport coefficients.
