Electrical resistivity calculations in dense plasmas

Issues in the calculations of dc conductivity of warm dense aluminum

“…In our precedent work on aluminum, the correction δη resulting from this extension was essential to explain experimental aluminum isobaric electrical conductivities. The other curves in Figure 1 reproduce the results of other studies, among which AA calculations with different choices for Z * , xc functional or ionic structure factor S(k) [13,14]. For information, we also reported other type of calculations like those based on mean-force scattering models [15,16], giving results comparable to AA ones.…”

“…Red line: our work [1]. Other lines: other Average-Atom results: Perrot and Dharmawardana [13], Faussurier and Blancard [14], approaches based on the mean-force scattering concept (Shaffer and Starrett [16], Sperling et al The impact of the exchange-correlation functional on aluminum's dc conductivity at solid density ρ 0 = 2.7 g/cm 3 is illustrated by the black curves (PDW: Perrot-Dharma-wardana [25,26], KS: Kohn-Sham [27]), that of the ion charge Z * by the blue line, and the impact of the ionic structure factor S(k) (OCP: One-Component Plasma, Rinker: Equation ( 28)) by the green ones. The red curve is our result for Z * = Z cont , Karasiev et al's exchange-correlation functional [9], and HyperNetted-Chain ionic structure factor.…”

[ 14,15 ] For information, we also reported other types of calculations like those based on mean‐force scattering models, [ 16,17 ] giving results comparable to AA ones. The neutral pseudo‐atom (NPA) calculation of Dharma‐wardana et al, [ 6 ] represented by the blue dashed curve, differs by the use of other boundary conditions.…”
