Kondo screening in Co adatoms with full Coulomb interaction
Angelo Valli, Marc Philipp Bahlke, Alexander Kowalski +3
Using a numerically exact first-principles many-body approach, we revisit the "prototypical" Kondo case of a cobalt impurity on copper. Even though this is considered a well unders…
Nonclassical optical properties of mesoscopic gold
Swen Großmann, Daniel Friedrich, Michael Karolak +5
Gold nanostructures have important applications in nanoelectronics, nano-optics as well as in precision metrology due to their intriguing opto-electronic properties. These properti…
Reversible magnetic switching of high-spin molecules on a giant Rashba surface
Jens Kügel, Michael Karolak, Andreas Krönlein +3
The quantum mechanical screening of a spin via conduction electrons depends sensitively on the environment seen by the magnetic impurity. A high degree of responsiveness can be obt…
On the origin of the quasi-particle peak in Cr(001) surfaces
L. Peters, D. Jacob, M. Karolak +2
In the spectral density of Cr(001) surfaces a sharp resonance close to the Fermi level is observed in both experiment and theory. For the physical origin of this peak two mechanism…
The interplay between strong correlation and adsorption distances
Marc Philipp Bahlke, Michael Karolak, Carmen Herrmann
Adsorbed transition metal atoms can have partially filled - or -shells due to strong on-site Coulomb interaction. Capturing all effects originating from electron correlation…
Realistic theory of electronic correlations in nanoscopic systems
M. Schüler, S. Barthel, T. Wehling +3
Nanostructures with open shell transition metal or molecular constituents host often strong electronic correlations and are highly sensitive to atomistic material details. This tut…
