Rigorous symmetry adaptation of multiorbital rotationally invariant slave-boson theory with application to Hund's rules physics
Christoph Piefke, Frank Lechermann
The theory of correlated electron systems on a lattice proves notoriously complicated because of the exponential growth of Hilbert space. Mean-field approaches provide valuable ins…

Low-Energy Model and Electron-Hole Doping Asymmetry of Single-Layer Ruddlesden-Popper Iridates
Alexander Hampel, Christoph Piefke, Frank Lechermann
We study the correlated electronic structure of single-layer iridates based on structurally-undistorted BaIrO. Starting from the first-principles band structure, the interp…
