Local Density of States in the Antiferromagnetic and Ferromagnetic Kondo Models

TL;DR

This paper computes the local density of states in both antiferromagnetic and ferromagnetic Kondo models across all band occupations and coupling strengths, providing new insights into their energy dependence.

Contribution

It introduces a simple approximation scheme to calculate the full energy-dependent LDOS for both models, a task not previously achieved.

Findings

LDOS computed across full range of parameters

Results are qualitatively trustworthy despite simplicity

Provides new energy-dependent LDOS data for both models

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.
