Photoemission from Ce Compounds: Exact Model Calculation in the Limit of Large Degeneracy

Gunnarsson, O., Schönhammer, K.·1983·Physical Review Letters

Abstract

A method is presented for calculating the core and valence spectra of a Ce compound in the impurity model at zero temperature. In the sudden limit this method becomes exact for large degeneracy of the $f$ level. In this limit the valence spectrum has an $f$ peak close to the Fermi energy, ${\ensuremath{\epsilon}}_{\mathrm{F}}$, even if the $f$ level is fairly far below ${\ensuremath{\epsilon}}_{\mathrm{F}}$, and usually there is a second $f$ peak at larger binding energy. These results correlate well with recent experiments for many Ce compounds. Both the core and valence spectra provide information about the occupancy of the $f$ level and about its coupling to the conduction band.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
