Towards Mott design by -doping of strongly correlated titanates
Frank Lechermann, Michael Obermeyer
Doping the distorted-perovskite Mott insulators LaTiO and GdTiO with a single SrO layer along the [001] direction gives rise to a rich correlated electronic structure. A re…
From Hubbard bands to spin-polaron excitations in the doped Mott material NaCoO
Aljoscha Wilhelm, Frank Lechermann, Hartmut Hafermann +2
We investigate the excitation spectrum of strongly correlated sodium cobaltate within a realistic many-body description beyond dynamical mean-field theory (DMFT). At lower doping a…
Hidden spin-orbital hexagonal ordering induced by strong correlations in LiVS
Lewin Boehnke, Alexander I. Lichtenstein, Mikhail I. Katsnelson +1
We present a first-principles many-body analysis of multi-orbital lattice susceptibilities in the metallic phase of the quasi-twodimensional compound LiVS. We base this on adva…
How chromium doping affects the correlated electronic structure of V2O3
Daniel Grieger, Frank Lechermann
The archetypical strongly correlated Mott-phenomena compound V2O3 is known to show a paramagnetic metal-insulator transition driven by doping with chromium atoms and/or (negative)…
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…
Theoretical prediction of a strongly correlated Dirac metal
I. I. Mazin, Harald O. Jeschke, Frank Lechermann +4
Recently, the most intensely studied objects in the electronic theory of solids have been strongly correlated systems and graphene. However, the fact that the Dirac bands in graphe…
