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…
Fano versus Kondo Resonances in a Multilevel "Semi-Open" Quantum Dot
Piotr Stefanski, Arturo Tagliacozzo, Bogdan R. Bulka
Linear conductance across a large quantum dot via a single level e_0 with large hybridization to the contacts is strongly sensitive to quasi-bound states localized in the dot and w…
Josephson versus Kondo coupling in a quantum dot connected to two superconductors
Gabriele Campagnano, Domenico Giuliano, Adele Naddeo +1
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. Our meth…
Linear Kondo conductance in a quantum dot
Domenico Giuliano, Adele Naddeo, Arturo Tagliacozzo
In a tunneling experiment across a quantum dot it is possible to change the coupling between the dot and the contacts at will, by properly tuning the trasparency of the barriers an…
