Model band structure calculations for heavy fermion systems

We present calculations of the quasiparticle band structure for simple heavy fermion systems, based on a mean-field approximation of the Anderson Hamiltonian. The aim of this investigation is to study the influence of the parameters of the Anderson Hamiltonian, position of thef-level and hybridization, on the quasiparticle bands and the form of the Fermi surface. We also calculate the static susceptibility.
