Transport through a single Anderson impurity coupled to one normal and two superconducting leads
Akira Oguri, Yoichi Tanaka
We study the interplay between the Kondo and Andreev-Josephson effects in a quantum dot coupled to one normal and two superconducting (SC) leads. In the large gap limit, the low-en…
1/(N-1) expansion for a finite U Anderson model away from half-filling
Akira Oguri
We apply recently developed 1/(N-1) expansion to a particle-hole asymmetric SU(N) Anderson model with finite Coulomb interaction U. To leading order in 1/(N-1) it describes the Har…
1/(N-1) expansion based on a perturbation theory in U for the Anderson model with N-fold degeneracy
Akira Oguri, Rui Sakano, Tatsuya Fujii
We study low-energy properties of the N-fold degenerate Anderson model. Using a scaling that takes u=(N-1) U as an independent variable in place of the Coulomb interaction U, the p…
Full counting statistics for SU(N) impurity Anderson model
Rui Sakano, Akira Oguri, Takeo Kato +1
We analyze the full counting statistics of a multiorbital Kondo effect in a quantum dotwith the SU(N) symmetry in the framework of the renormalized perturbation theory. The current…
