Andreev reflection eigenvalue density in mesoscopic conductors
P. Samuelsson, W. Belzig, Yu. V. Nazarov
The energy-dependent Andreev reflection eigenvalues determine the transport properties of normal-superconducting systems. We evaluate the eigenvalue density to get an insight into…
Transport through ferromagnet/superconductor interfaces
Zhigang Jiang, Jose Aumentado, Wolfgang Belzig +1
The differential resistance of submicron-size ferromagnet/superconductor interface structures shows asymmetries as a function of the current through the ferromagnet/superconductor…
Shot Noise in Mesoscopic Diffusive Andreev Wires
Wolfgang Belzig
We study shot noise in mesoscopic diffusive wires between a normal and a superconducting terminal. We particularly focus on the regime, in which the proximity-induced reentrance ef…
Full counting statistics of multiple Andreev reflections
J. C. Cuevas, W. Belzig
We derive the full distribution of transmitted particles through a superconducting point contact of arbitrary transparency under voltage bias. The charge transport is dominated by…
Spin-Flip Noise in a Multi-Terminal Spin-Valve
W. Belzig, M. Zareyan
We study shot noise and cross correlations in a four terminal spin-valve geometry using a Boltzmann-Langevin approach. The Fano factor (shot noise to current ratio) depends on the…
Decoherence of cold atomic gases in magnetic micro-traps
C. Schroll, W. Belzig, C. Bruder
We derive a model to describe decoherence of atomic clouds in atom-chip traps taking the excited states of the trapping potential into account. We use this model to investigate dec…
