【 摘 要 】

Recently, Affleck derived the existence of Friedel oscillations in the presence of a Kondo impurity. They supported their analytic derivation by numerical calculations using Wilson's numerical renormalization group (NRG). In this paper the size of the Friedel oscillations is calculated with the Friedel artificially inserted resonance (FAIR) method which has been recently developed. The results of NRG and FAIR are compared. The development of Friedel oscillations with a phase shift of pi/2 outside of the Kondo radius is confirmed.
