Resistivity Exponents in 3D-Dirac Semimetals From Electron-Electron Interaction
Niklas Wagner, Sergio Ciuchi, Alessandro Toschi +2
We study the resistivity of three-dimensional semimetals with linear dispersion in the presence of on-site electron-electron interaction. The well-known quadratic temperature depen…
Momentum-space signatures of Berry flux monopoles in a Weyl semimetal
M. Ünzelmann, H. Bentmann, T. Figgemeier +14
Since the early days of Dirac flux quantization, magnetic monopoles have been sought after as a potential corollary of quantized electric charge. As opposed to magnetic monopoles e…
Observation of tunable single-atom Yu-Shiba-Rusinov states
Artem Odobesko, D. Di Sante, A. Kowalski +5
The coupling of a spin to an underlying substrate is the basis for a plethora of phenomena. In the case of a metallic substrate, Kondo screening of the adatom magnetic moment can o…
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…
Attractive effect of a strong electronic repulsion -- the physics of vertex divergences
M. Reitner, P. Chalupa, L. Del Re +4
While the breakdown of the perturbation expansion for the many-electron problem has several formal consequences, here we unveil its physical effect: Flipping the sign of the effect…
Deconfinement of Mott Localized Electrons into Topological and Spin-Orbit Coupled Dirac Fermions
José M. Pizarro, Severino Adler, Karim Zantout +5
The interplay of electronic correlations, spin-orbit coupling and topology holds promise for the realization of exotic states of quantum matter. Models of strongly interacting elec…
