Abstract
We perform model calculations for the electrical and thermal conductivity of aluminium plasma within the generalized linear response method of Zubarev for temperatures of (5–25) eV and densities of (0.01–10) g/cm3. The composition in the expanded plasma region is determined by considering higher ionization states up to 5+ and solving the respective system of coupled mass action laws. Besides this chemical picture, a generalized Thomas-Fermi model is applied to calculate the equation of state and the average charge state of the ions for densities near and above solid state density. Interactions between the various species are treated on T matrix level. Numerical results for the electrical and thermal conductivity of aluminium plasma are compared with experimental data and, for high densities, also with results of a Born approximation with respect to a weak electron-ion pseudopotential.
