摘要: Abstract Green's functions relevant to the periodic Anderson Hamiltonian are evaluated via perturbation theory around atomic limit, within an approximation that reproduces exact results in three different limits: zero band width, hybridization and Coulomb correlation. The magnetic susceptibility electronic specific heat calculated for both Kondo intermediate valence regimes. qualitative agreement with experiments can be related other theoretical calculations.
