Dynamic structure factor of the correlated one-component plasma — •Hanno Kählert — Institut für Theoretische Physik und Astrophysik, Christian-Albrechts-Universität zu Kiel

The dynamic structure factor (DSF) plays an important role for the analysis of x-ray scattering spectra of dense plasmas. Here, molecular dynamics simulations are used to obtain first-principle data for the DSF of the classical one-component plasma (OCP), in particular for intermediate coupling strengths. In this regime, a theoretical description is challenging due to strong coupling and collisional effects. The results are compared with theoretical models for the DSF and are used to compute the local-field correction, which measures the deviations of the DSF from the Vlasov (mean-field) result.
