A local moment approach to magnetic impurities in gapless Fermi systems
A local moment approach is developed for single-particle excitations of a symmetric Anderson impurity model (AIM) with a soft-gap hybridization vanishing at the Fermi level: Δ I α |ω| r, with r > 0. Local moments are introduced explicitly from t...
