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…
Singlet-Triplet Mixing in Superconductor-Ferromagnet Hybrid Devices
M. Eschrig, J. Kopu, A. Konstandin +3
We develop a theory which describes hybrid structures consisting out of superconducting and ferromagnetic parts. We give two examples for applications. First, we consider a hybrid…
Shot noise in tunneling transport through molecules and quantum dots
Axel Thielmann, Matthias H. Hettler, Jürgen König +1
We consider electrical transport through single molecules coupled to metal electrodes via tunneling barriers. Approximating the molecule by the Anderson impurity model as the simpl…
Dephasing and Renormalization in Quantum Two-Level Systems
Alexander Shnirman, Gerd Schön
Motivated by fundamental questions about the loss of phase coherence at low temperature we consider relaxation, dephasing and renormalization effects in quantum two-level systems w…
Low-temperature Dephasing and Renormalization in Model Systems
Dmitri S. Golubev, Gerd Schön, Andrei D. Zaikin
We investigate low-temperature dephasing in several model systems, where a quantum degree of freedom is coupled to a bath. Dephasing, defined as the decay of the coherence of inita…
Comment on "Absence of electron dephasing at zero temperature"
Dmitri S. Golubev, Andrei D. Zaikin, Gerd Schön
The recent claim by Kirkpatrick and Belitz (cond-mat/0111398) that Ward identities could be used to prove the absence of electron dephasing at T=0 contains serious flaws. These aut…
