摘要

The Friedel artificially inserted resonance (FAIR) magnetic state is extended from the one-channel to the multichannel Friedel-Anderson problem in this paper. The magnetic pseudoground state of the multichannel Friedel-Anderson problem is constructed from a product of one-channel magnetic states of each individual channel. A Hamiltonian that is rotationally invariant in both spin space and real space, which was developed by Dworin, Narath, and Parmenter, is used in the calculation. The magnetic ground-state energy is obtained through optimization of the conduction-band basis and Slater-state coefficients. The FAIR solution yields a considerably lower energy than the mean-field solution and requires a much larger Coulomb energy to form a magnetic moment.
