This is a renewal of NSF grant ECS-8645108 and represents collaborative work with G. J. Kalman of Boston College (ECS-8716328). Continued theoretical work on collective modes and dynamical transport coefficients of strongly coupled plasmas is to be carried out. The theoretical scheme developed by Golden and Kalman and already successfully applied to various physical situations will be employed to the study of physical systems of engineering importance. These include electron gas in metals, 2-dimensional electron gas in MOS devices, heterostructures and molten salts. All these systems share the property that the Couloumb interaction between the particles is strong which renders the use of customary perturbation methods inadequate. The GK scheme is a novel non-perturbative approach developed for the analysis of such systems.
