Influence of photon-assisted tunneling on heat flow in a normal metal - superconductor tunnel junction
N. B. Kopnin, F. Taddei, J. P. Pekola +1
We have investigated theoretically the influence of an AC drive on heat transport in a hybrid normal metal - superconductor tunnel junction in the photon-assisted tunneling regime.…
Superconductors as ideal spin sources for spintronics
F. Giazotto, F. Taddei
Spin-polarized transport is investigated in normal metal-superconductor (NS) junctions as a function of interface transmissivity as well as temperature when the density of states o…
Multi-channel architecture for electronic quantum-Hall interferometry
Vittorio Giovannetti, Fabio Taddei, Diego Frustaglia +1
We propose a new architecture for implementing electronic interferometry in quantum Hall bars. It exploits scattering among parallel edge channels. In contrast to previous developm…
Nonequilibrium spin-dependent phenomena in mesoscopic superconductor-normal metal tunnel structures
F. Giazotto, F. Taddei, P. D'Amico +2
We analyze the broad range of spin-dependent nonequilibrium transport properties of hybrid systems composed of a normal region tunnel coupled to two superconductors with exchange f…
Properties of Mesoscopic Hybrid Superconducting Systems
F. Taddei, F. Giazotto, R. Fazio
In this paper we review several aspects of mesoscopic hybrid superconducting systems. In particular we consider charge and heat transport properties in hybrid superconducting-metal…
Landau Cooling in Metal-Semiconductor Nanostructures
F. Giazotto, F. Taddei, M. Governale +2
An electron-cooling principle based on Landau quantization is proposed for nanoscale conductor systems. Operation relies on energy-selective electron tunneling into a two-dimension…
Characterizing electron entanglement in multiterminal mesoscopic conductors
Vittorio Giovannetti, Diego Frustaglia, Fabio Taddei +1
We show that current correlations at the exit ports of a beam splitter can be used to detect electronic entanglement for a fairly general input state. This includes the situation w…
