Abstract: | Using Bardeen's disorder scattering model we calculate the single-particle occupation function for liquid metals. Our results demonstrate that the blurring of the Fermi surface is considerable in liquids with short mean free path. Finally, using an appropriate dielectric function, we obtain the effective ion-ion interaction which shows how the Friedel oscillations are damped in the liquid. |
