Density functional theory study of the α−γ phase transition in cerium: Role of electron correlation and f-orbital localization

Our new paper on "Density functional theory study of the α−γ phase transition in cerium: Role of electron correlation and f-orbital localization" just appeared in Physical Review B (http://journals.aps.org/prb/abstract/10.1103/PhysRevB.93.075153). We study the phase transition  and the associated volume collapse in cerium with the random-phase approximation, an advanced density functional. Our results suggest that the phase transition should already occur at zero temperature, and therefore could be directly related to the hybridization between f states. The localization or delocalization of the f-states is an outcome of the calculations and is not require as an input.
