Dynamical mean-field theory of the Anderson-Hubbard model with local and non-local disorder in tensor formulation
A. Weh, Y. Zhang, A. Östlin +7
To explore correlated electrons in the presence of local and non-local disorder, the Blackman-Esterling-Berk method for averaging over off-diagonal disorder is implemented into dyn…
Impact ionization and multiple photon absorptions in the two-dimensional photoexcited Hubbard model
F. Maislinger, H. G. Evertz
We study the non-equilibrium response of a 4x3 Hubbard model at U=8 under the influence of a short electric field pulse, with the main focus on multiple photon excitations and on t…
Spectral properties of heterostructures containing half-metallic ferromagnets in the presence of local many-body correlations
A. Weh, J. Otsuki, H. Schnait +4
In this work, we investigate models for bulk, bi- and multilayers containing half-metallic ferromagnets (HMFs), at zero and at finite temperature, in order to elucidate the effects…
Comparison of MPS based real time evolution algorithms for Anderson Impurity Models
Daniel Bauernfeind, Markus Aichhorn, Hans Gerd Evertz
We perform a detailed comparison of two Matrix Product States (MPS) based time evolution algorithms for Anderson Impurity Models. To describe the bath, we use both the star-geometr…
Dynamical Mean-Field Theory on the Real-Frequency Axis: p-d Hybridizations and Atomic Physics in SrMnO
Daniel Bauernfeind, Robert Triebl, Manuel Zingl +2
We investigate the electronic structure of SrMnO with Density Functional Theory (DFT) plus Dynamical Mean-Field Theory (DMFT). Within this scheme the selection of the correlate…
Interaction effects in a microscopic quantum wire model with strong spin-orbit interaction
Georg W. Winkler, Martin Ganahl, Dirk Schuricht +2
We investigate the effect of strong interactions on the spectral properties of quantum wires with strong Rashba spin-orbit interaction in a magnetic field, using a combination of M…
