Fermi-Liquid Effects on Plasma Wave Propagation in Metals

Abstract

The dispersion relation for plasma waves propagating perpendicular to a dc magnetic field in a metal with a spherical Fermi surface is studied. It is found that the dispersion relation differs only slightly from the prediction of the free-electron model. The experimental data can be used to estimate the value of the interaction coefficient $A_2$, but they should be independent of $A_0$ and $A_1$.
