Atomic-state-dependent screening model for hot and warm dense plasmas

Abstract An ion embedded in warm/hot dense plasmas will greatly alter its microscopic structure and dynamics, as well the macroscopic radiation transport properties of plasmas, due to complicated many-body interactions with surrounding particles. Accurate theoretically modeling such kind quantum is essential but very challenging. In this work, we propose an atomic-state-dependent screening model for treating a wide range temperatures densities, which contributions three-body recombination processes are included. We show that electron distributions around strongly correlated ionic state studied processes. The feasibility validation proposed demonstrated by reproducing experimental result line-shift hot-dense classical molecular dynamic simulations moderately coupled ultra-cold neutral plasmas. Our work opens promising way treat effect hot warm plasma, bottleneck those extensive studies high-energy-density physics, atomic plasma spectra properties, among others.
