The relativistic 5f electronic structure of delocalized $\hat{I}\pm$-U and localized $\hat{I}´$-Pu from the self consistent vertex corrected GW approach and X-ray Emission Spectroscopy

Abstract

The recently developed self-consistent vertex corrected GW method is used to calculate the 5f electronic structure in delocalized $\hat{I}\pm$-U and localized $\hat{I}´$-Pu, each of which is confirmed by the historical experimental approaches of direct and inverse photoemission. Tender X-Ray Emission Spectroscopy (XES), in a novel application to 5f electronic structure, is used to experimentally prove the existence of 5f delocalization in $\hat{I}\pm$-U.
