Coherent quasiparticle transport in grain boundary junctions employing high-Tc superconductors
F. Tafuri, A. Tagliacozzo, D. Born +8
Magneto-fluctuations of the normal resistance RN have been reproducibly observed in YBa2Cu3O7-d biepitaxial grain boundary junctions at low temperatures. We attribute them to mesos…
Quantum Rings with Rashba spin orbit coupling: a path integral approach
P. Lucignano, D. Giuliano, A. Tagliacozzo
We employ a path integral real time approach to compute the DC conductance and spin polarization for electrons transported across a ballistic Quantum Ring with Rashba spin-orbit in…
Quantum interference of electrons in a ring: tuning of the geometrical phase
R. Capozza, D. Giuliano, P. Lucignano +1
We calculate the oscillations of the DC conductance across a mesoscopic ring, simultaneously tuned by applied magnetic and electric fields orthogonal to the ring. The oscillations…
Josephson Current in a Quantum Dot in the Kondo Regime Connected to Two Superconductors
G. Campagnano, D. Giuliano, A. Tagliacozzo
We apply a Gutzwiller-like variational technique to study Josephson conduction across a quantum dot with an odd number of electrons connected to two superconducting leads. We show…
