Figure 3: This figure shows the coefficients of the state for three different impurities, F: Friedel, FA: Friedel-Anderson, and K: Kondo. The coefficients are counted from the Fermi level. Most curves are for , but one curve is for a FA impurity with and . The curve shown is super-universal because it is independent of the kind of impurity (F, FA, K), independent of , and independent of and other parameters as long as there is a resonance exactly at the Fermi level.
