Doping-driven Mott transition from steady-state density functional theory
David Jacob, Stefan Kurth
We describe the doping-driven Mott transition in the Hubbard model within the framework of steady-state density functional theory, or i-DFT. In order to access the many-body spectr…
Analytic approach to thermoelectric transport in double quantum dots
Nahual Sobrino, David Jacob, Stefan Kurth
A recently proposed analytical solution for the equations of motion of the one-body Green function of the double quantum dot is extended to the out-of-equilibrium situation. By sol…
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…
Beyond spin models in orbitally-degenerate open-shell nanographenes
J. C. G. Henriques, D. Jacob, A. Molina-Sánchez +3
The study of open-shell nanographenes has relied on a paradigm where spins are the only low-energy degrees of freedom. Here we show that some nanographenes can host low-energy exci…
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…
Mott metal-insulator transition from steady-state density functional theory
David Jacob, Gianluca Stefanucci, Stefan Kurth
We present a computationally efficient method to obtain the spectral function of bulk systems in the framework of steady-state density functional theory (i-DFT) using an idealized…
