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…
Hanle Effect in Transport through Quantum Dots Coupled to Ferromagnetic Leads
Matthias Braun, Jürgen König, Jan Martinek
We suggest a series of transport experiments on spin precession in quantum dots coupled to one or two ferromagnetic leads. Dot spin states are created by spin injection and analyze…
Gate-controlled spin-splitting in quantum dots with ferromagnetic leads in the Kondo regime
J. Martinek, M. Sindel, L. Borda +6
The effect of a gate voltage () on the spin-splitting of an electronic level in a quantum dot (QD) attached to ferromagnetic leads is studied in the Kondo regime using a gener…
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…
NRG study of the Kondo effect in the presence of itinerant-electron ferromagnetism
J. Martinek, M. Sindel, L. Borda +4
The Kondo effect in quantum dots (QDs) - artificial magnetic impurities - attached to ferromagnetic leads is studied with the numerical renormalization group (NRG) method. It is sh…
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…
