Review of the first charged-particle transport coefficient comparison workshop

We present the results of the first Charged-Particle Transport Coefficient Code Comparison Workshop, which was held in Albuquerque, NM October 4–6, 2016 in the context of planning for a second workshop. Scientists gathered to compare calculations of transport coefficients including thermal and electrical conduction, electron–ion coupling, inter-ion diffusion, ion viscosity, and stopping powers. We give background on Coulomb coupling and computational expense and present the submitted data. Large variations are found when either the relevant Coulomb coupling parameter or computational expense is large. We will present scientific goals and open questions for the next workshop. Understanding the accuracy of such transport coefficients is important for quantifying errors in high-energy-density hydrodynamic simulations and experiments.
