Hysteretic magnetotransport in p-type AlGaAs heterostructures with In/Zn/Au ohmic contacts
B. Grbic, R. Leturcq, T. Ihn +4
The two-terminal magneto-conductance of a hole gas in C-doped AlGaAs/GaAs heterostructures with ohmic contacts consisting of alloyed In/Zn/Au displays a pronounced hysteresis of th…
N-particle scattering matrix for electrons interacting on a quantum dot
A. V. Lebedev, G. B. Lesovik, G. Blatter
We present a non-perturbative expression for the scattering matrix of particles interacting inside a quantum dot. Characterizing the dot by its resonances, we find a compact fo…
Effects of Exchange Symmetry on Full Counting Statistics
F. Hassler, G. B. Lesovik, G. Blatter
We study the full counting statistics for the transmission of two identical particles with positive or negative symmetry under exchange for the situation where the scattering depen…
Entanglement in Mesoscopic Structures: Role of Projection
A. V. Lebedev, G. Blatter, C. W. J. Beenakker +1
We present a theoretical analysis of the appearance of entanglement in non-interacting mesoscopic structures. Our setup involves two oppositely polarized sources injecting electron…
Transport in a One-Dimensional Superfluid: Quantum Nucleation of Phase Slips
H. P. Büchler, V. B. Geshkenbein, G. Blatter
We present an analytical derivation for the quantum decay rate of the superflow through a weak link in a one-dimensional Bose-Einstein-condensate. The effective action for the phas…
Supercurrent Quantization in Narrow Channel SNS Junctions
Nikolai M. Chtchelkatchev, Gordey B. Lesovik, Gianni Blatter
We determine the quasi-particle excitation spectrum in the normal region of a narrow ballistic superconductor--normal-metal--superconductor (SNS) Josephson contact. Increasing the…
