Enhanced damping of ion acoustic waves in dense plasmas

Abstract

A theory for the ion acoustic wave damping in dense plasmas and warm dense matter, accounting for the Umklapp process, is presented. A higher decay rate compared to the prediction from the Landau damping theory is predicted for high-Z dense plasmas where the electron density ranges from $10^{21}$ to $10^{24}\mathrm{c}{\mathrm{m}}^{-3}$ and the electron temperature is moderately higher than the Fermi energy.
