Full Counting Statistics for a Single-Electron Transistor, Non-equilibrium Effects at Intermediate Conductance
Yasuhiro Utsumi, Dmitri S. Golubev, Gerd Schön
We evaluate the current distribution for a single-electron transistor with intermediate strength tunnel conductance. Using the Schwinger-Keldysh approach and the drone (Majorana) f…
Nonequilibrium Kondo Effect in a Quantum Dot Coupled to Ferromagnetic Leads
Yasuhiro Utsumi, Jan Martinek, Gerd Schön +2
We study the Kondo effect in the electron transport through a quantum dot coupled to ferromagnetic leads, using a real-time diagrammatic technique which provides a systematic descr…
Indirect Exchange Interaction between two Quantum Dots in an Aharonov-Bohm Ring
Yasuhiro Utsumi, Jan Martinek, Patrick Bruno +1
We investigate the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction between two spins located at two quantum dots embedded in an Aharonov-Bohm (AB) ring. In such a system the RKKY…
Kondo effect in quantum dots coupled to ferromagnetic leads
J. Martinek, Y. Utsumi, H. Imamura +4
We study the Kondo effect in a quantum dot which is coupled to ferromagnetic leads and analyse its properties as a function of the spin polarization of the leads. Based on a scalin…
