The self-consistent determination of HF electroconductivity of strongly coupled plasmas

Abstract

Here is presented the calculation of the dynamic electrical conductivity of fully ionized, strongly coupled plasmas as a function of the external electric field frequency $\omega$. The calculations are based on the the formula for the energy-dependent collision frequency which is determined by means of the Green function theory methods, as a sum over the Matsubara frequencies. The domain of extremely high electron density: $10^{21}\le n_e\le 10^{24}{\text{cm}}^{-3}$, and for the temperature varying from $10\text{kK}$ to $1.000\text{kK}$ was examined. The real and imaginary parts of the conductivity for every electron density are presented in the generalized Drude-like form as a two-parameter function of the frequency $\omega$ in the region $0<\omega <0.5{\omega }_p$, where ${\omega }_p$ is the plasma frequency. A good agreement between the obtained results and the existing theoretical and computing simulation data is shown.
