Charge and pairing dynamics in the attractive Hubbard model: mode coupling and the validity of linear-response theory
Jörg Bünemann, Götz Seibold
Pump-probe experiments have turned out as a powerful tool in order to study the dynamics of competing orders in a large variety of materials. The corresponding analysis of the data…
Quasi-particle bands and structural phase transition of iron from Gutzwiller Density-Functional Theory
Tobias Schickling, Jörg Bünemann, Florian Gebhard +1
We use the Gutzwiller Density Functional Theory to calculate ground-state properties and bandstructures of iron in its body-centered-cubic (bcc) and hexagonal-close-packed (hcp) ph…
Coexistence of Nematic Order and Superconductivity in the Hubbard Model
Jan Kaczmarczyk, Tobias Schickling, Jörg Bünemann
We study the interplay of nematic and superconducting order in the two-dimensional Hubbard model and show that they can coexist, especially when superconductivity is not the energe…
Gutzwiller variational wave function for multi-orbital Hubbard models in finite dimensions
Kevin zu Münster, Jörg Bünemann
We develop a diagrammatic method for the evaluation of general multi-band Gutzwiller wave functions in finite dimensions. Our approach provides a systematic improvement of the wide…
Even-parity spin-triplet pairing for orbitally degenerate correlated electrons by purely repulsive interactions
Michał Zegrodnik, Jörg Bünemann, Jozef Spałek
We demonstrate the stability of a spin-triplet paired s-wave (with an admixture of extended s-wave) state for the case of purely repulsive interactions in a degenerate two-band Hub…
A slave-boson mean-field theory for general multi-band Hubbard models
J. Bünemann
We introduce a new slave-boson mean-field theory which allows the investigation of general multi-band Hubbard models. Unlike earlier attempts of such a generalisation, in our appro…
