Abstract
The dynamic characteristics of strongly coupled classical single-component Coulomb and Yukawa plasmas are obtained in a non-perturbative approach based on the free moment model without input of simulation data, so that the dynamic structure factor (DSC-DSF) automatically satisfies the first three nonvanishing sum rules. DSC-DSF, dispersion, attenuation, speed of sound, and other characteristics of collective oscillations are determined only using the static structure coefficient calculated within the framework of modified or classical hypergrid chain approximations. Good quantitative agreement is achieved with all available molecular dynamics’ simulation data.
