Transport properties of Hydrogen and CH under ICF conditions

We present ab initio evaluations of the thermal and of the electrical conductivity of hydrogen at a density of 80 g/cc [1] and 160 g/cc corresponding to the Inertial Confinement Fusion regime. Results are compared with different theories (Hubbard, Lee-More, Ichimaru) and with an average atom (AA) model coupled with a Kubo-Greenwood evaluation of transport coefficients. The Lorentz number, which is the ratio between the thermal to the electrical conductivity, given by the Wiedemann-Frantz law is checked in different regimes ranging from the highly degenerate to the kinetic one. We have also used ab initio calculations to compute the CH thermal conductivity and compared it to the AA approach using mixing rules.\\[4pt] [1] V. Recoules, F. Lambert, A. Decoster, B.
