PHOTOEMISSION SPECTRUM OF THE ANDERSON MODEL WITH CONDUCTION ELECTRON SCREENING

The symmetric Anderson model with conduction electron screening has been studied in the Kondo regime using the numerical renormalization group method. A renormalization of both the Coulomb repulsion U(ff) and the hybridization strength DELTA is found in the static and dynamic properties. The same set of renormalized parameters is consistent with both the valence-band PES and BIS spectra and the thermodynamic properties.
