Donarini, Andrea and Begemann, Georg and Grifoni, Milena (2010) Interference effects in the Coulomb blockade regime: Current blocking and spin preparation in symmetric nanojunctions. Phys. Rev. B 82, p. 125451.
We consider nanojunctions in the single-electron tunneling regime which, due to a high degree of spatial symmetry, have a degenerate many-body spectrum. As a consequence, interference phenomena which cause a current blocking can occur at specific values of the bias and gate voltage. We present here a general formalism to give necessary and sufficient conditions for interference blockade also in ...
