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…
Co-tunneling current and shot noise in quantum dots
A. Thielmann, M. H. Hettler, J. König +1
We derive general expressions for the current and shot noise, taking into account non-Markovian memory effects. In generalization of previous approaches our theory is valid for arb…
Low- and high-frequency noise from coherent two-level systems
Alexander Shnirman, Gerd Schön, Ivar Martin +1
Recent experiments indicate a connection between the low- and high-frequency noise affecting superconducting quantum systems. We explore the possibilities that both noises can be p…
Super-poissonian noise, negative differential conductance, and relaxation effects in transport through molecules, quantum dots and nanotubes
A. Thielmann, M. H. Hettler, J. König +1
We consider charge transport through a nanoscopic object, e.g. single molecules, short nanotubes, or quantum dots, that is weakly coupled to metallic electrodes. We account for sev…
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…
