Abstract
A self-consistent Green function theory of the Anderson lattice Hamiltonian is presented. The approximations include spin and charge fluctuations beyond mean field and are similar to previous approximations made for the impurity problem by Theumann (1969). The self-energy integral equations are solved exactly and the static physical properties are obtained for almost the entire strongly mixed valent regime. The temperature dependence of the electronic specific heat, C(T), gamma (T)=C(T)/T, densities of states, Fermi level and valence are discussed for both one and two electrons per atom. The behaviour of gamma (T) is similar to that found experimentally.
