Versatile Approach to the Spin Dynamics in Correlated Electron Systems
Malte Behrmann, Alexander I. Lichtenstein, Mikhail I. Katsnelson +1
Time-dependent spin phenomena in condensed matter are most often either described in the weakly correlated limit of metallic Stoner/Slater-like magnetism via band theory or in the…
Large-amplitude spin oscillations triggered by nonequilibrium strongly correlated electrons
Malte Behrmann, Frank Lechermann
Laser-induced ultrafast (fs) magnetization experiments in antiferromagnets have recently attracted large attention, paving the road for inherently fast spin dynamics in the THz reg…
Extended dynamic Mott-transition in the two-band Hubbard model out of equilibrium
Malte Behrmann, Michele Fabrizio, Frank Lechermann
We reformulate the time-dependent Gutzwiller approximation by M. Schiró and M. Fabrizio [Phys. Rev. Lett. 105, 076401 (2010)] in the framework of slave-boson mean-field theory, whi…
Multi-orbital physics in Fermi liquids prone to magnetic order
Malte Behrmann, Christoph Piefke, Frank Lechermann
The interplay of spin-orbit-coupling and strong electronic correlations is studied for the single-layer and the bilayer compound of the strontium ruthenate Ruddlesden-Popper series…
