Abstract
An electron scattering from a local impurity spin has its density of states altered by spin-flip scattering. This phenomenon causes a peak in the local density of states, which is called the ‘‘Kondo resonance.’’ We propose a simple formula for the shape of this resonance. For a dilute Kondo system, we use Fermi-liquid theory to calculate the effect of the Kondo resonance on the heat capacity, magnetic susceptibility, and resistivity. Good agreement is found when compared to exact solutions.
