The connection between noise and quantum correlations in a double quantum dot
F. Bodoky, W. Belzig, C. Bruder
We investigate the current and noise characteristics of a double quantum dot system. The strong correlations induced by the Coulomb interaction create entangled two-electron states…
Nanospintronics with carbon nanotubes
Audrey Cottet, Takis Kontos, Sangeeta Sahoo +6
One of the actual challenges of spintronics is the realization of a spin-transistor allowing to control spin transport through an electrostatic gate. In this review, we report on d…
Shot-noise and conductance measurements of transparent superconductor / two-dimensional electron gas junctions
B. -R. Choi, A. E. Hansen, T. Kontos +6
We have measured the conductance and shot-noise of superconductor-normal metal (S-N) junctions between a Niobium (Nb) film and a 2-dimensional electron gas (2DEG), formed in an InA…
Kondo Effect and Josephson Current through a Quantum Dot between Two Superconductors
Mahn-Soo Choi, Minchul Lee, Kicheon Kang +1
We investigate the supercurrent through a quantum dot for the whole range of couplings using the numerical renormalization group method. We find that the Josephson current switches…
Positive cross-correlations in a three-terminal quantum dot with ferromagnetic contacts
A. Cottet, W. Belzig, C. Bruder
We study current fluctuations in an interacting three-terminal quantum dot with ferromagnetic leads. For appropriately polarized contacts, the transport through the dot is governed…
Full Counting Statistics of Superconductor--Normal-Metal Heterostructures
W. Belzig
The article develops a powerful theoretical tool to obtain the full counting statistics. By a slight extension of the standard Keldysh method we can access immediately all correlat…
