Electronic Structure of Compressed Americium Metal

We report a theoretical investigation of changes in the electronic structure of americium metal due to applied pressure. We employ a variant of the LDA+DMFT method that takes into account not only the correlations among the 5f electrons, but also a feedback of these correlations on the rest of the system by means of an appropriate adjustment of the electronic charge density. We observe only minor modifications of the electronic structure in the compressed lattice, which is in accord with recent resonant x-ray spectroscopy experiments.JRC.E.6-Actinide researc
