Seebeck effect in the conducting LaAlO_{3}/SrTiO_{3} interface
I. Pallecchi, M. Codda, E. Galleani d'Agliano +5
The observation of metallic behavior at the interface between insulating oxides has triggered worldwide efforts to shed light on the physics of these systems and clarify some still…
Non-adiabatic pumping through interacting quantum dots
Fabio Cavaliere, Michele Governale, Jürgen König
We study non-adiabatic two-parameter charge and spin pumping through a single-level quantum dot with Coulomb interaction. For the limit of weak tunnel coupling and in the regime of…
Microwave Assisted Transport in a Single Donor Silicon Quantum Dot
Enrico Prati, Rossella Latempa, Marco Fanciulli
Single donors in semiconductor nanostructures represent a key element to develop spin related quantum functionalities in atomic scale devices. Quantum transport through a single Ar…
Time Dependent Inelastic Emission and Capture of Localized Electrons in Si n-MOSFETs Under Microwave Irradiation
Enrico Prati, Marco Fanciulli, Alessandro Calderoni +2
Microwave irradiation causes voltage fluctuations in solid state nanodevices. Such an effect is relevant in atomic electronics and nanostructures for quantum information processing…
A novel approach to transport through correlated quantum dots
C. Karrasch, T. Enss, V. Meden
We investigate the effect of local Coulomb correlations on electronic transport through a variety of coupled quantum dot systems connected to Fermi liquid leads. We use a newly dev…

Matteo Merlo, Nicodemo Magnoli, Maura Sassetti +1
The relation between the conductivity tensors of Composite Fermions and electrons is extended to second generation Composite Fermions. It is shown that it crucially depends on the…

Enrico Prati, Marco Fanciulli, Giorgio Ferrari +1
We report on the static magnetic field dependence of the random telegraph signal (RTS) in a submicrometer silicon n-metal-oxide-semiconductor field-effect transistor. Using intense…
Shot noise in charge and magnetization currents of a quantum ring
F. Cavaliere, F. Haupt, R. Fazio +1
The shot noise in a quantum ring, connected to leads, is studied in the presence of electron interactions in the sequential tunneling regime. Two qualitatively different noise corr…
Initial decoherence in solid state qubits
G. Falci, A. D'Arrigo, A. Mastellone +1
We study decoherence due to low frequency noise in Josephson qubits. Non-Markovian classical noise due to switching impurities determines inhomogeneous broadening of the signal. Th…
Decoherence due to telegraph and 1/f noise in Josephson qubits
E. Paladino, A. Mastellone, A. D'Arrigo +1
We study decoherence due to random telegraph and 1/f noise in Josephson qubits. We illustrate differences between gaussian and non gaussian effects at different working points and…
Magneto-elastic instability in Molecular Antiferromagnetic Rings
L. Spanu, A. Parola
Lattice stability in a model of antiferromagnetic ring coupled to adiabatic phonons is investigated for different values of the spin and numbers of magnetic sites. The magneto-elas…

G. Falci, A. D'Arrigo, A. Mastellone +1
We study dynamical decoupling of a qubit from non gaussian quantum noise due to discrete sources, as bistable fluctuators and 1/f noise. We obtain analytic and numerical results fo…

The chiral Luttinger liquid model for the edge dynamics of a two-dimensional electron gas in a strong magnetic field is derived from coarse-graining and a lowest Landau level proje…

We study electron transport through a quantum dot in a Tomonaga-Luttinger liquid with an inhomogeneity induced either by a non-uniform electron interaction or by the presence of tu…
