摘要：

Quasiparticle excitations of Landau-Fermi liquids can be described by a Boltzmann-Landau transport equation. We use this property to characterize the Fermi-liquid state of correlated metals, and discuss leading corrections to standard results of Fermi-liquid theory. Our non-Fermi liquid corrections are smaller than the standard results by a factor small(D-1), where D is the dimension of the metal and small represents the expansion parameters of Fermi-liquid theory. We present, as an instructive example, results for the first-order non-Fermi liquid corrections to Korringa's law.
