Abstract

We calculate from first principles the high-frequency high-temperature conductivity of metals and find that to dominant order the temperature-dependent collision frequency is given by ν(T) = ν1(T/Tm) + ν2(T/Tm)2, where Tm represents the melting temperature and ν1 and ν2 are independent of T. The origin of the quadratic-temperature term arises from the contribution of the anharmonic ion potential near melting to the phonon spectra.
