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…
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…
Spin state of negative charge-transfer material SrCoO3
J. KuneÅ¡, V. KÅápek, N. Parragh +3
We employ the combination of the density functional and the dynamical mean-field theory (LDA+DMFT) to investigate the electronic structure and magnetic properties of SrCoO3, monocr…
A Microscopic View on the Mott transition in Chromium-doped V2O3
S. Lupi, L. Baldassarre, B. Mansart +18
V2O3 is the prototype system for the Mott transition, one of the most fundamental phenomena of electronic correlation. Temperature, doping or pressure induce a metal to insulator t…
