Evidence for out-of-equilibrium states in warm dense matter probed by x-ray Thomson scattering

TL;DR: A recent and unexpected discrepancy between ab initio simulations and the interpretation of a laser shock experiment on aluminum probed by x-ray Thomson scattering (XRTS), is addressed and the relevance of decoupled temperatures for ions and electrons is discussed.
Journal ArticleDOI

Behavior of the coupling parameter under isochoric heating in a high-Z plasma.

TL;DR: It is shown that along an isochore the effective ionic coupling parameter is almost constant over a wide range of temperatures (in this case Γ~/=20) due to the competition between rising temperatures and increased ionization.
Journal ArticleDOI

Simple calculation of ab initio melting curves: Application to aluminum.

TL;DR: A simple, fast, and promising method to compute the melting curves of materials with ab initio molecular dynamics, based on the two-phase thermodynamic model of Lin et al, comparable to the most sophisticated methods, for a much lower computational cost.
Journal ArticleDOI

Thomas-Fermi Z-scaling laws and coupling stabilization for plasmas.

TL;DR: This work investigates the stabilization of the ionic coupling in isochoric heating by extending the well-known Thomas-Fermi Z-scaling laws to the Coulomb coupling parameter, and quantifies the consequences for corresponding states via orbital free molecular dynamics simulations.
