Half-metallicity in NiMnSb: a Variational Cluster Approach with ab-initio parameters
H. Allmaier, L. Chioncel, E. Arrigoni +2
Electron correlation effects in the half-metallic ferromagnet NiMnSb are investigated within a combined density functional and many-body approach. Starting from a realistic multi-o…

Titanium Nitride - a correlated metal at the threshold of a Mott transition
H. Allmaier, L. Chioncel, E. Arrigoni
We investigate electron correlation effects in stoichiometric Titanium Nitride (TiN) using a combination of electronic structure and many-body calculations. In a first step, the Nt…

Dispersive spectrum and orbital order of spinless p-band fermions in an optical lattice
Xiancong Lu, E. Arrigoni
We study single-particle properties of a spinless p-band correlated fermionic gas in an optical lattice by means of a variational cluster approach (VCA). The single-particle spectr…
