Open Wilson chains for quantum impurity models: Keeping track of all bath modes
Benedikt Bruognolo, Nils-Oliver Linden, Frauke Schwarz +6
When constructing a Wilson chain to represent a quantum impurity model, the effects of truncated bath modes are neglected. We show that their influence can be kept track of systema…
Realistic quantum critical point in one-dimensional two-impurity models
Benedikt Lechtenberg, Fabian Eickhoff, Frithjof B. Anders
We show that the two-impurity Anderson model exhibits an additional quantum critical point at infinitely many specific distances between both impurities for an inversion symmetric…
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…
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…
