Local Density of States in the Antiferromagnetic and Ferromagnetic Kondo Models
P. Sinjukow, D. Meyer, W. Nolting
Abstract
Based on a simple approximation scheme we have computed the local density of states (LDOS) of the antiferromagnetic and ferromagnetic Kondo models for the full range of band occupations and coupling strengths. For both models the LDOS with its full energy dependence has not been calculated before. Arguments are given for the results to be qualitatively trustworthy despite the simplicity of the approximation scheme.
