Gutzwiller Density Functional Theory: a formal derivation and application to ferromagnetic nickel
Tobias Schickling, Jörg Bünemann, Florian Gebhard +1
We present a detailed derivation of the Gutzwiller Density Functional Theory that covers all conceivable cases of symmetries and Gutzwiller wave functions. The method is used in a…
Numerical minimisation of Gutzwiller energy functionals
Jörg Bünemann, Florian Gebhard, Tobias Schickling +1
We give a comprehensive introduction into an efficient numerical scheme for the minimisation of Gutzwiller energy functionals in studies on multi-band Hubbard models. Our method co…
Gutzwiller theory of band magnetism in LaOFeAs
Tobias Schickling, Florian Gebhard, Jörg Bünemann +3
We use the Gutzwiller variational theory to calculate the ground-state phase diagram and quasi-particle bands of LaOFeAs. The Fe3d--As4p Wannier-orbital basis obtained from density…
Renormalization of Bulk Magnetic Electron States at High Binding Energies
A. Hofmann, X. Y. Cui, J. Schaefer +11
The quasiparticle dynamics of electrons in a magnetically ordered state is investigated by high-resolution angle-resolved photoemission of Ni(110) at 10 K. The self-energy is extra…
Spin-orbit coupling in ferromagnetic Nickel
J. Bünemann, F. Gebhard, T. Ohm +2
We use the Gutzwiller variational theory to investigate the electronic and the magnetic properties of fcc-Nickel. Our particular focus is on the effects of the spin-orbit coupling.…
Gutzwiller-Correlated Wave Functions: Application to Ferromagnetic Nickel
Joerg Buenemann, Florian Gebhard, Torsten Ohm +2
Ferromagnetic Nickel is the most celebrated iron group metal with pronounced discrepancies between the experimental electronic properties and predictions of density functional theo…
