Abstract:

A general method is presented for the calculation of static transport coefficients based on Kubos formulas. Techniques of perturbation expansion, diagram representation, and linked-cluster expansion are used. As an example, the electrical conductivity of an electron-phonon system is calculated with the natural introduction of irreversibility, following the ideas of Van Hove, Physica 21517, 1955 23441, 1957, PrigogineAND HIS COLLABORATORS Non-equilibrium Statistical Mechanics, Interscience, New York, 1961 and Physica 22621, 1956 25281, 1959 25302, 1959 26145, 1960. Under certain conditions the present method is shown to be equivalent to the conventional method by means of the Boltzmann equation. These conditions are examined and the improvement of the appnoximation is discussed. Author
