Combining semi-local exchange with dynamical mean-field theory: electronic structure and optical response of rare-earth sesquioxides
James Boust, Anna Galler, Silke Biermann +1
In rare-earth semiconductors, wide ligand and rare-earth 5 bands coexist with localized, partially filled 4 shells. A simultaneous description for both extended and local…
Intershell Interactions in Correlated Materials: A Slave Rotor Approach
Jakob Steinbauer, Silke Biermann
The treatment of intershell interactions remains a major challenge in the theoretical description of strongly correlated materials. Most previous approaches considered the influenc…
Electronic correlations at paramagnetic and NiO surfaces: Charge-transfer and Mott-Hubbard-type gaps at the surface and subsurface of NiO
I. Leonov, S. Biermann
We explore the interplay of electron-electron correlations and surface effects in the prototypical correlated insulating material, NiO. In particular, we compute the electronic str…
Correlated electronic structure and optical response of rare-earth-based semiconductors
Anna Galler, James Boust, Alain Demourgues +2
Simultaneous occurrence of the Mott and band gap in correlated semiconductors results in a complex optical response with the nature of the absorption edge difficult to resolve both…
