DC Transport Coeffcient Calculation by a Derivatives of Time Correlation Functions. II. Application to the Case of Liquid Metals and Alloys

Abstract

Formula for electric resistivity ρ, derived in the first part of this work has developed to the case when the coupling of carriers to the rest part of many particle system, can be described by a local pseudopotential, like to the case of liquid metals and alloys. Resistivity of liquid alkali metals has been calculated, and specific lines of numerical calculations by the new formula have been analysed and comments given. According to our results, the scattering of carriers accompanied by the wave vector transfer in amount of q, is of essential importance, not only for q<2k_f, but also for q above of double Fermi radius k_f, q>2k_f, in opposite to the Ziman’s formula, which takes into consideration and accounts only the region q<2k_f.
