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…
Quantum model for mode locking in pulsed semiconductor quantum dots
Wouter Beugeling, Götz S. Uhrig, Frithjof B. Anders
Quantum dots in GaAs/InGaAs structures have been proposed as a candidate system for realizing quantum computing. The short coherence time of the electronic quantum state that arise…
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…
Spin noise of electrons and holes in (In,Ga)As quantum dots: experiment and theory
P. Glasenapp, D. S. Smirnov, A. Greilich +4
The spin fluctuations of electron and hole doped self-assembled quantum dot ensembles are measured optically in the low-intensity limit of a probe laser in absence and presence of…
