Correlation effects on the doped triangular lattice in view of the physics of sodium-rich NaCoO
Frank Lechermann
The peculiar correlation effects on the triangular lattice are studied by means of the rotationally invariant slave boson method in a cellular cluster approach. Hence nonlocal corr…
Plane-wave based electronic structure calculations for correlated materials using dynamical mean-field theory and projected local orbitals
B. Amadon, F. Lechermann, A. Georges +3
The description of realistic strongly correlated systems has recently advanced through the combination of density functional theory in the local density approximation (LDA) and dyn…
Competing itinerant and localized states in strongly correlated BaVS
Frank Lechermann, Silke Biermann, Antoine Georges
The electronic structure of the quasi-lowdimensional vanadium sulfide \bavs3 is investigated for the different phases above the magnetic ordering temperature. By means of density f…
Rotationally-invariant slave-boson formalism and momentum dependence of the quasiparticle weight
Frank Lechermann, Antoine Georges, Gabriel Kotliar +1
We generalize the rotationally-invariant formulation of the slave-boson formalism to multiorbital models, with arbitrary interactions, crystal fields, and multiplet structure. This…
Dynamical mean-field theory using Wannier functions: a flexible route to electronic structure calculations of strongly correlated materials
F. Lechermann, A. Georges, A. Poteryaev +4
A versatile method for combining density functional theory (DFT) in the local density approximation (LDA) with dynamical mean-field theory (DMFT) is presented. Starting from a gene…
Interorbital charge transfers and Fermi-surface deformations in strongly correlated metals: models, BaVS and NaCoO
Frank Lechermann, Silke Biermann, Antoine Georges
Fermi-surface deformations in strongly correlated metals, in comparison to results from band-structure calculations, are investigated. We show that correlation-induced interband ch…
