Calculating Transport Coeffiecients in Warm Dense Matter

In warm dense matter and high energy density plasmas, the traditional Boltzmann description begins to break down. In this regime, collisions are not determined by binary Coulomb collisions, but instead by many body Coulomb collisions. The Mean Force Kinetic Theory (MFKT) [S. D. Baalrud and J. Daligault, Phys. Plasmas 26, 082106 (2019)] provides an alternate closure to the BBGKY hierarchy based on expanding about a perturbation from equilibrium rather than about strength of correlations. The MFKT produces the usual fluid equations, with altered transport coefficients and equation of state (EOS), thus existing fluid codes would only need to update transport and EOS tables. A code is presented which solves for transport coefficients in the warm dense matter regime using a Chapman-Enskog expansion for the MFKT. These plasmas contain degenerate electrons, whose screening effect are modeled by the potential of mean force which is obtained using the Quantum Hyper Netted Chain Model (QHNC) [C. E. Starrett and D. Saumon, High Energy Density Phys. 10, 35 (2014)]. Future work intends to develop a module to expand transport coefficients to an arbitrary order in the Chapman-Enskog expansion, and a model for electron transport properties.
