Frustration of decoherence in -shaped superconducting Josephson networks
D. Giuliano, P. Sodano
We examine the possibility that pertinent impurities in a condensed matter system may help in designing quantum devices with enhanced coherent behaviors. For this purpose, we analy…
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…
Boundary Field Theory Approach to the Renormalization of SQUID Devices
Domenico Giuliano, Pasquale Sodano
We show that the quantum properties of some Josephson SQUID devices are described by a boundary sine Gordon model. Our approach naturally describes multi-junction SQUID devices and…
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…
Hamiltonian theory of the strongly-coupled limit of the Kondo problem in the overscreened case
Domenico Giuliano, Arturo Tagliacozzo
By properly generalizing Nozie`res' Fermi liquid theory, we construct an Hamiltonian approach to the scattering of conduction electrons off a spin-1/2 impurity in the ovescreneed K…
