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…
Mesoscopic supercurrent transistor controlled by nonequilibrium cooling
F. Giazotto, T. T. Heikkila, F. Taddei +3
The distinctive quasiparticle distribution existing under nonequilibrium in a superconductor-insulator-normal metal-insulator-superconductor (SINIS) mesoscopic line is proposed as…
Ultra-efficient Cooling in Ferromagnet-Superconductor Microrefrigerators
F. Giazotto, F. Taddei, R. Fazio +1
A promising scheme for electron microrefrigeration based on ferromagnet-superconductor contacts is presented. In this setup, cooling power densities up to 600 nW/m can be a…
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…
Electronic implementations of Interaction-Free Measurements
L. Chirolli, E. Strambini, V. Giovannetti +5
Three different implementations of interaction-free measurements (IFMs) in solid-state nanodevices are discussed. The first one is based on a series of concatenated Mach-Zehnder in…
Josephson nanocircuit in the presence of linear quantum noise
E. Paladino, F. Taddei, G. Giaquinta +1
We derive the effective hamiltonian for a charge-Josephson qubit in a circuit with no use of phenomenological arguments, showing how energy renormalizations induced by the environm…
