Charge correlation, doublon-holon binding and screening in the doped Hubbard model
Edin Kapetanović, Guglielmo Nicola Gigante, Malte Schüler +2
Electronic correlations arise from the competition between the electrons' kinetic and Coulomb interaction energy and give rise to a rich phase diagram and many emergent quasipartic…

Nonlocal Exchange Interactions in Strongly Correlated Electron Systems
Edin Kapetanović, Malte Schüler, Gerd Czycholl +1
We study the influence of ferromagnetic nonlocal exchange on correlated electrons in terms of a -Hubbard-Heisenberg model and address the interplay of on-site interaction in…
