Renormalized perturbation calculations for the single-impurity Anderson model
We illustrate the renormalized perturbation expansion method by applying it to a single-impurity Anderson model. Previously, we have shown that this approach gives the exact leading-order results for the specific heat, spin and charge susceptibilities and leading-order temperature dependence of the resistivity for this model in the Fermi-liquid regime, when …
