We review the electronic structure of nickelate superconductors with and without effects of
electronic correlations. As a minimal model, we identify the one-band Hubbard model for the …

The WIEN2k program is based on the augmented plane wave plus local orbitals (APW+ lo)
method to solve the Kohn–Sham equations of density functional theory. The APW+ lo …

Reticular materials rely on a unique building concept where inorganic and organic building
units are stitched together giving access to an almost limitless number of structured ordered …

Controlling and understanding electron correlations in quantum matter is one of the most
challenging tasks in materials engineering. In the past years a plethora of new puzzling …

The recently discovered nickelate superconductors appear, at first glance, to be even more
complicated multi-orbital systems than cuprates. To identify the simplest model describing …

We use the topological heavy fermion (THF) model and its Kondo lattice (KL) formulation to
study the possibility of a symmetric Kondo (SK) state in twisted bilayer graphene. Via a large …

We briefly review the status quo of research on the putative superconductor Pb 9 Cu (PO 4)
6 O also known as LK-99. Further, we provide ab initio derived tight-binding parameters for a …

Motivated by the recent discovery of superconductivity in the pentalayer nickelate Nd 6 Ni 5
O 12 [GA Pan, Nat. Mater. 21, 160 (2022) 10.1038/s41563-021-01142-9], we calculate its …
