Electronic correlations in short period (CrAs)/(GaAs) ferromagnetic heterostructures
L. Chioncel, I. Leonov, H. Allmaier +4
We investigate half-metallicity in [001] stacked (CrAs)/(GaAs) heterostructures with by means of a combined many-body and electronic structure calculation. Inter…
Rare-earth impurities in CoMnSi: an opportunity to improve Half-Metallicity at finite temperatures
E. Burzo, I. Balazs, L. Chioncel +2
We analyse the effects of doping Holmium impurities into the full-Heusler ferromagnetic alloy CoMnSi. Experimental results, as well as theoretical calculations within Density F…
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…
Majority-spin non-quasiparticle states in half-metallic ferrimagnet MnVAl
L. Chioncel, E. Arrigoni, M. I. Katsnelson +1
The density of non-quasiparticle states in the ferrimagnetic full-Heuslers MnVAl alloy is calculated from first principles upon appropriate inclusion of correlations. In contra…
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…
