Electronic Correlation Effects in Plutonium Metals
An understanding of the phase diagram of elemental plutonium (Pu) must include both the effects of the strong directional bonding and the high density of states of the Pu 5f electrons, as well as how that bonding weakens under the influence of strong electronic correlations. In this talk, I will give an LDA+DMFT perspective on the electronic correlation effects in elemental Pu solids. After a brief overview of the earlier results of electronic structure calculations on the δ-phase of Pu, I will discuss the Kondo physics of Pu impurity in a non-interacting bath, and then proceed to discuss the electronic structure of the true α-phase of Pu with the LDA+DMFT approach.
