    Notes: Summary The viscosity coefficient entering sound wave attenuation is evaluated for the liquid alkali metals in an ion-electron plasma approach. It is shown that the contribution from electrical conduction, though small, is by no means negligible. The calculated longitudinal viscosity is very close to the measured shear viscosity contribution, the bulk viscosity being expected to be small in the present approach.

    Linear-response theory for partly quenched systems (1994)

    Notes: Summary The matrix of linear density response functions is constructed within density functional theory for a monatomic fluid adsorbed in a quenched material. The structural Ornstein-Zernike relations obtained by Given and Stell with the replica method are regained in the appropriate limit. The usefulness of the present reformulation of their theory is illustrated by deriving from it the free-energy functional and the structural closure relations in the hypernetted-chain approximation. The extension to dynamical properties of partly quenched systems is indicated.

    A model for the metal-non-metal transition in metal-molten-salt solutions (1994)
    Springer
    Il nuovo cimento della Società Italiana di Fisica 16 (1994), S. 307-310

    Notes: Summary We outline a theory for the metal-non-metal transition occurring in solutions of alkali metals in molten alkali halides as governed by a balance between the binding of ionic clusters by localized electrons and the excess free energy of an ionic assembly screened by metallic electrons. In the model the transition is driven by the composition dependence of the screening length. The theory is amenable to an analytic solution within the mean spherical approximation when Thomas-Fermi screening is used and the ions are described by charged hard spheres.
