Electronic correlations, magnetism and Hund's rule coupling in the ruthenium perovskites SrRuO and CaRuO
Hung T. Dang, Jernej Mravlje, Antoine Georges +1
A comparative density functional plus dynamical mean field theory study of the pseudocubic ruthenate materials CaRuO and SrRuO is presented. Phase diagrams are determined f…
Low-energy description of the metal-insulator transition in the rare-earth nickelates
Alaska Subedi, Oleg E. Peil, Antoine Georges
We propose a simple theoretical description of the metal-insulator transition of rare-earth nickelates. The theory involves only two orbitals per nickel site, corresponding to the…
A weakly correlated Fermi liquid state with a small Fermi surface in lightly doped SrIrO
Alberto de la Torre, Emily Claire Hunter, Alaska Subedi +7
We characterize the electron doping evolution of (SrLa)IrO by means of angle-resolved photoemission. Concomitant with the metal insulator transition around…
Non-existence of the Luttinger-Ward functional and misleading convergence of skeleton diagrammatic series for Hubbard-like models
Evgeny Kozik, Michel Ferrero, Antoine Georges
The Luttinger-Ward functional , which expresses the thermodynamic grand potential in terms of the interacting single-particle Green's function , is found…
Orbital Polarization in Strained LaNiO: Structural Distortions and Correlation Effects
Oleg E. Peil, Michel Ferrero, Antoine Georges
Transition-metal heterostructures offer the fascinating possibility of controlling orbital degrees of freedom via strain. Here, we investigate theoretically the degree of orbital p…
Momentum space anisotropy and pseudogaps: a comparative cluster dynamical mean field analysis of the doping-driven metal-insulator transition in the two dimensional Hubbard model
Emanuel Gull, Michel Ferrero, Olivier Parcollet +2
Cluster dynamical mean field calculations based on 2, 4, 8 and 16 site clusters are used to analyze the doping-driven metal-insulator transition in the two dimensional Hubbard mode…
