Friedel Oscillation about a Friedel-Anderson Impurity
Yaqi Tao, Gerd Bergmann
The Friedel oscillations in the vicinity of a Friedel-Anderson (FA) impurity are investigated numerically. For an FA impurity in the local moment limit the normalized amplitude A(ξ…

Numerical Calculation of the Fidelity for the Kondo and the Friedel-Anderson Impurities
Gerd Bergmann, Richard S. Thompson
The fidelities of the Kondo and the Friedel-Anderson (FA) impurities are calculated numerically. The ground states of both systems are calculated with the FAIR (Friedel artificiall…
