Single-Co Kondo effect in atomic Cu wires on Cu(111)
Nicolas Néel, Jörg Kröger, Malte Schüler +4
Linear atomic chains containing a single Kondo atom, Co, and several nonmagnetic atoms, Cu, were assembled atom by atom on Cu(111) with the tip of a scanning tunneling microscope.…
Coulomb-Engineered Heterojunctions and Dynamical Screening in Transition Metal Dichalcogenide Monolayers
Christina Steinke, Tim O. Wehling, Malte Rösner
The manipulation of two-dimensional materials via their dielectric environment offers novel opportunities to control electronic as well as optical properties and allows to imprint…
Turbulent hydrodynamics in strongly correlated Kagome metals
Domenico Di Sante, Johanna Erdmenger, Martin Greiter +6
A current challenge in condensed matter physics is the realization of strongly correlated, viscous electron fluids. These fluids are not amenable to the perturbative methods of Fer…
Nonlocal Exchange Interactions in Strongly Correlated Electron Systems
Edin Kapetanović, Malte Schüler, Gerd Czycholl +1
We study the influence of ferromagnetic nonlocal exchange on correlated electrons in terms of a -Hubbard-Heisenberg model and address the interplay of on-site interaction in…
Ab initio phonon self-energies and fluctuation diagnostics of phonon anomalies: Lattice instabilities from Dirac pseudospin physics in transition metal dichalcogenides
Jan Berges, Erik G. C. P. van Loon, Arne Schobert +2
We present an ab initio approach for the calculation of phonon self-energies and their fluctuation diagnostics, which allows us to identify the electronic processes behind phonon a…
Introducing strong correlation effects into graphene by gadolinium intercalation
S. Link, S. Forti, A. Stöhr +11
Exotic ordered ground states driven by electronic correlations are expected to be induced in monolayer graphene when doped to the Van Hove singularity. Such doping levels are reach…
