Mixed-state aspects of an out-of-equilibrium Kondo problem in a quantum dot
Akira Oguri
We reexamine basic aspects of a nonequilibrium steady state in the Kondo problem for a quantum dot under a bias voltage using a reduced density matrix, which is obtained in the Foc…
Transport theory for interacting electrons connected to reservoirs
Akira Oguri
We describe microscopic theory for the quantum transport through finite interacting systems connected to noninteracting leads. It can be applied to small systems such as quantum do…
Kondo effect in asymmetric Josephson couplings through a quantum dot
Yoshihide Tanaka, Akira Oguri, A. C. Hewson
Asymmetry in the Josephson couplings between two superconductors through a quantum dot is studied based on a single impurity Anderson model using the numerical renormalization grou…
Kondo screening of a high-spin Nagaoka state in a triangular quantum dot
Akira Oguri, Yunori Nisikawa, Yoshihide Tanaka +1
We study transport through a triangle triple quantum dot connected to two noninteracting leads using the numerical renormalization group (NRG). The triangle has a high-spin ground…
