Interference effects in the Coulomb blockade regime: current blocking and spin preparation in symmetric nanojunctions
Andrea Donarini, Georg Begemann, Milena Grifoni
We consider nanojunctions in the single-electron tunnelling regime which, due to a high degree of spatial symmetry, have a degenerate many body spectrum. As a consequence, interfer…
Inelastic cotunneling in quantum dots and molecules with weakly broken degeneracies
Georg Begemann, Sonja Koller, Milena Grifoni +1
We calculate the nonlinear cotunneling conductance through interacting quantum dot systems in the deep Coulomb blockade regime using a rate equation approach based on the T-matrix…
All-electric-spin control in interference single electron transistors
Andrea Donarini, Georg Begemann, Milena Grifoni
Single particle interference lies at the heart of quantum mechanics. The archetypal double-slit experiment has been repeated with electrons in vacuum up to the more massive $C_{60}…
Symmetry fingerprints of a benzene single-electron transistor
Georg Begemann, Dana Darau, Andrea Donarini +1
The interplay between Coulomb interaction and orbital symmetry produces specific transport characteristics in molecular single electron transistors (SET) that can be considered as…
Transport through a double quantum dot system with non-collinearly polarized leads
Ralph Peter Hornberger, Sonja Koller, Georg Begemann +2
We investigate linear and non-linear transport in a double quantum dot system weakly coupled to spin-polarized leads. In the linear regime, the conductance as well as the non-equil…
