Abstract
The ground-state energy, hybridization matrix element, local moment, and spin-density correlations of a one-dimensional, finite-chain, periodic, symmetric Anderson model are obtained by numerical simulations and compared with perturbation theory and strong-coupling results. We find that the local f-electron spins are compensated by correlation with other f electrons as well as band electrons leading to a nonmagnetic ground state.Keywords
