Quantum-Many-Body Intermetallics: Phase Stability of FeAl and Small-Gap Formation in FeVAl
Oleg Kristanovski, Raphael Richter, Igor Krivenko +2
Various intermetallic compounds harbor subtle electronic correlation effects. To elucidate this fact for the Fe-Al system, we perform a realistic many-body investigation based on t…
Electron dichotomy on the SrTiO defect surface augmented by many-body effects
Frank Lechermann, Harald O. Jeschke, Aaram J. Kim +2
In a common paradigm, the electronic structure of condensed matter is divided into weakly and strongly correlated compounds. While conventional band theory usually works well for t…
Unconventional electron states in -doped SmTiO
Frank Lechermann
The Mott-insulating distorted perovskite SmTiO, doped with a single SrO layer in a quantum-well architecture is studied by the combination of density functional theory with dyn…
Hubbard band or oxygen vacancy states in the correlated electron metal SrVO?
S. Backes, T. C. Rödel, F. Fortuna +19
We study the effect of oxygen vacancies on the electronic structure of the model strongly correlated metal SrVO. By means of angle-resolved photoemission (ARPES) synchrotron ex…
Versatile Approach to the Spin Dynamics in Correlated Electron Systems
Malte Behrmann, Alexander I. Lichtenstein, Mikhail I. Katsnelson +1
Time-dependent spin phenomena in condensed matter are most often either described in the weakly correlated limit of metallic Stoner/Slater-like magnetism via band theory or in the…
Thermopower enhancement from engineering the NaCoO interacting fermiology via Fe doping
Raphael Richter, Denitsa Shopova, Wenjie Xie +2
The sodium cobaltate system NaCoO is a prominent representant of strongly correlated materials with promising thermoelectric response. In a combined theoretical and exper…
