Mixing Rules in Strongly Coupled Plasmas

Type: conference-abstract
Abstract: An accurate and efficient prediction of the equation of state (EOS) is necessary for hydrodynamic simulations of plasmas. As most plasmas are multi-component by nature, the EOS must be known across the entire parameter space of each species. As such, “mixing rules” are often used, which approximate the value of the full, multi-component EOS in terms of a combination of single-component EOS values. The most common mixing rules used in practice are Dalton's Law, which states the pressure is determined by the sum of partial pressures of each species, and Amagat's Law, which states that the volume is determined by the sum of partial volumes of each species. While both laws have regimes of applicability, they break down for strongly-coupled plasmas, where many-body correlations between ions become non-negligible.
