Electronics with correlated oxides: SrVO/SrTiO as a Mott transistor
Zhicheng Zhong, Markus Wallerberger, Jan M. Tomczak +5
We employ density functional theory plus dynamical mean field theory and identify the physical origin of why two layers of SrVO on a SrTiO substrate are insulating: the thi…
Importance of d-p Coulomb interaction for high T cuprates and other oxides
Philipp Hansmann, Nicolaus Parragh, Alessandro Toschi +2
Current theoretical studies of electronic correlations in transition metal oxides typically only account for the local repulsion between d-electrons even if oxygen ligand p-states…
Local moment dynamics and screening effects in doped charge-transfer insulators
A. Amaricci, N. Parragh, M. Capone +1
By means of Dynamical Mean-Field Theory we investigate the spin response function of a model for correlated materials with d- or f-electrons hybridized with more delocalized ligand…
Correlation effects in transport properties of interacting nanostructures
A. Valli, G. Sangiovanni, A. Toschi +1
We discuss how to apply many-body methods to correlated nanoscopic systems, and provide general criteria of validity for a treatment at the dynamical mean field theory (DMFT) appro…
Effective crystal field and Fermi surface topology: a comparison of d- and dp-orbital models
N. Parragh, G. Sangiovanni, P. Hansmann +3
The effective crystal field in multi-orbital correlated materials can be either enhanced or reduced by electronic correlations with crucial consequences for the topology of the Fer…
Divergent Precursors of the Mott-Hubbard Transition at the Two-Particle Level
T. Schäfer, G. Rohringer, O. Gunnarsson +3
Identifying the fingerprints of the Mott-Hubbard metal-insulator transition may be quite elusive in correlated metallic systems if the analysis is limited to the single particle le…
