Demonstrating Kondo behavior by temperature-dependent scanning tunneling spectroscopy
Elia Turco, Markus Aapro, Somesh C. Ganguli +9
The Kondo effect describes the scattering of conduction electrons by magnetic impurities, manifesting as an electronic resonance at the Fermi energy with a distinctive temperature…
Observation of the Ferromagnetic Kondo Effect
Elia Turco, Nils Krane, Hongyan Chen +5
The quest for quantum ground states beyond the conventional Fermi-liquid paradigm remains a central challenge in many-body physics. The ferromagnetic Kondo effect represents a part…
Fully analytical equation of motion approach for the double quantum dot in the Coulomb blockade regime
Nahual Sobrino, David Jacob, Stefan Kurth
A fully analytical approach based on the equation of motion technique to investigate the spectral properties and orbital occupations in an interacting double quantum dot in equilib…
What can lattice DFT teach us about real-space DFT?
Nahual Sobrino, David Jacob, Stefan Kurth
In this paper we establish a connection between density functional theory (DFT) for lattice models and common real-space DFT. We consider the lattice DFT description of a two-level…
Emergence of half-metallicity in suspended NiO chains
David Jacob, J. Fernández-Rossier, J. J. Palacios
Contrary to the antiferromagnetic and insulating character of bulk NiO, one-dimensional chains of this material can become half-metallic due to the lower coordination of their atom…
Magnetic and orbital blocking in Ni nanocontacts
David Jacob, J. Fernández-Rossier, J. J. Palacios
We address the fundamental question of whether magneto-resistance (MR) of atomic-sized contacts of Nickel is very large because of the formation of a domain wall (DW) at the neck.…
