Dynamical Properties of Strongly Coupled Plasmas

Dynamical properties of strongly coupled Yukawa plasmas are obtained over the entire liquid phase using highly-converged molecular dynamics. We obtain the dynamic structure factor, the ion-acoustic wave dispersion relations, and the intermediate scattering functions; these are compared with many theoretical approaches. In particular, we examine high frequency tails and find that most current theoretical models are unable to properly capture this feature. We also examine the opposite (hydrodynamic) limit and find important nonlocal viscosity corrections missed by most current models.
