Diffusion in Coulomb Plasmas Across Coupling Regimes

We use molecular dynamics simulations to calculate the diffusion coefficients of Coulomb plasmas with percent-level precision. In previous work we focused on screening lengths typical for white dwarf astrophysics and developed a simple empirical model for diffusion for use in stellar evolution codes. In this work, we perform additional simulations over a wider range of couplings to further generalize our model, which may have applications in charged soft matter systems.
