TABLE I. Optimal temperature range for fitting the conductance G(T ,0) to the Fermi-liquid form f (T /T 0 ) = a[1 − c T (T /T 0 ) 2 ] for U/ = 12 and ε d = −U/2 using a goodness of fit based on the value of R 2
Figure 3 shows c T versus U for the symmetric model, both in terms of the scale T 0 (ε d = −U/2) ≡ T 0 (s) and in terms of the Kondo scale from the conductance T K expt (i.e., c exptT , discussed below)
Figure 7 compares SPT results for the local level depen- depen-dence of c T
