- Abstract:
- We calculate the spectral functions of model systems describing 5f compounds adopting cluster perturbation theory. The method allows for an accurate treatment of the short-range correlations. The calculated excitation spectra exhibit coherent 5f bands coexisting with features associated with local intra-atomic transitions. The findings provide a microscopic basis for partial localization. Results are presented for linear chains.
