Abstract
We investigate the normal state of the superconducting compound using the combination of density functional theory (DFT) and dynamical mean-field theory (DMFT), with the continuous time quantum Monte Carlo (CTQMC) and the vertex-corrected one-crossing approximation (OCA) as the impurity solvers. Our DFT+DMFT (CTQMC) calculations suggest a strong tendency of Pu- orbitals to differentiate at low temperatures. The renormalized states exhibit a Fermi-liquid behavior whereas one electron in the states is at the edge of a Mott localization. We find that the orbital differentiation is manifested as the removing of spectral weight from the Fermi level relative to DFT. We corroborate these conclusions with DFT+DMFT (OCA) calculations which demonstrate that electrons have a much larger Kondo scale than the .
