Exchange couplings for Mn ions in CdTe: validity of spin models for dilute magnetic II-VI semiconductors
Thorben Linneweber, Jörg Bünemann, Ute Löw +2
We employ density-functional theory (DFT) in the generalized gradient approximation (GGA) and its extensions GGA+ and GGA+Gutzwiller to calculate the magnetic exchange couplings…
Approximation schemes for the study of multi-band Gutzwiller wave functions
Jörg Bünemann, Thorben Linneweber, Florian Gebhard
The minimum of the Gutzwiller energy functional depends on the number of parameters considered in the variational state. For a three-orbital Hubbard model we find that the frequent…
Interplay of Coulomb interaction and spin-orbit coupling
Jörg Bünemann, Thorben Linneweber, Ute Löw +2
We employ the Gutzwiller variational approach to investigate the interplay of Coulomb interaction and spin-orbit coupling in a three-orbital Hubbard model. Already in the paramagne…
