Current-voltage correlations in interferometers
Heidi Forster, Peter Samuelsson, Markus Buttiker
We investigate correlations of current at contacts and voltage fluctuations at voltage probes coupled to interferometers. The results are compared with correlations of current and…
Quantum pump driven fermionic Mach-Zehnder interferometer
S. -W. V. Chung, M. Moskalets, P. Samuelsson
We have investigated the characteristics of the currents in a pump-driven fermionic Mach-Zehnder interferometer. The system is implemented in a conductor in the quantum Hall regime…
Voltage and dephasing probes: a full counting statistics discussion
Heidi Forster, Peter Samuelsson, Sebastian Pilgram +1
Voltage and dephasing probes introduce incoherent inelastic and incoherent quasi-elastic scattering into a coherent mesoscopic conductor. We discuss in detail the concepts of volta…
Vortex localization in rotating clouds of bosons and fermions
S. M. Reimann, M. Koskinen, Y. Yu +1
Finite quantal systems at high angular momenta may exhibit vortex formation and localization. These phenomena occur independent of the statistics of the repulsively interacting par…
Fano effect in a ring-dot system with tunable coupling
A. Fuhrer, P. Brusheim, T. Ihn +4
Transport measurements are presented on a quantum ring that is tunnel-coupled to a quantum dot. When the dot is in the Coulomb blockade regime, but strongly coupled to the open rin…
Classical Nuclear Motion in Quantum Transport
Claudio Verdozzi, Gianluca Stefanucci, Carl-Olof Almbladh
An ab initio quantum-classical mixed scheme for the time evolution of electrode-device-electrode systems is introduced to study nuclear dynamics in quantum transport. Two model sys…
