Effect of non-local correlations on the electronic structure of LiFeAs
Karim Zantout, Steffen Backes, Roser Valentí
We investigate the role of non-local correlations in LiFeAs by exploring an ab-initio-derived multi-orbital Hubbard model for LiFeAs via the Two-Particle Self-Consistent (TPSC) app…

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…
