    Correlated electrons in δ-plutonium within a dynamical mean-field picture

    Given the practical importance of metallic plutonium, there is considerable interest1,2,3 in understanding its fundamental properties. Plutonium undergoes a 25 per cent increase in volume4 when transformed from i...

    Model Hamiltonians and First Principles Electronic Structure Calculations

    We review the basic ideas of the dynamical mean field theory (DMFT). Some of the remarkable insights into the electronic structure of strongly correlated electrons are introduced using the simplest model Hamil...

    Electron–Phonon Coupling and Properties of Doped BaBiO3

    Density functional calculations based on local density approximation (LDA) of the properties of doped barium bismuthates are reported. Using a linear-response approach within the linear-muffin-tin-orbital meth...

    Out-of-plane instability and electron-phonon contribution tos- andd-wave pairing in high-temperature superconductors; LDA linear-response calculation for doped CaCuO2 and a generic tight-binding model

    The equilibrium structure, energy bands, phonon dispersions, and s- and d-channel electron-phonon interactions (EPIs) are calculated for the infinite-layer superconductor CaCuO2 doped with 0.12 holes per CuO2. Th...
