We study the effect of a magnetic field in the Kondo regime of a double-quantum-dot system
consisting of a strongly correlated dot (the “side dot”) coupled to a second, noninteracting …

We study the linear conductance through a double-quantum-dot system consisting of an
interacting dot in its Kondo regime and an effectively noninteracting dot connected in …

We demonstrate delicate control over the Kondo effect and its interplay with quantum
interference in an Aharonov-Bohm interferometer containing one Kondo dot and one …

We calculate the conductance through rings with few sites L described by the tJ model,
threaded by a magnetic flux Φ and weakly coupled to conducting leads at two arbitrary sites …

We consider a Hubbard-Anderson model which describes localized orbitals in five different
sites hybridized both among themselves and with a continuum of extended states. A square …

Several of the most interesting quantum effects can or could be observed in nanoscopic
systems. For example, the effect of strong correlations between electrons and of quantum …

We derive the extension of the Hubbard model to include Rashba spin–orbit coupling that
correctly describes Aharonov-Bohm and Aharonov-Casher phases in a ring under applied …

We consider a triple-quantum-dot (TQD) system composed by an interacting quantum dot
connected to two effectively noninteracting dots, which in turn are both connected in parallel …

Electron correlations in quantum-dot structures result in many fascinating effects that can be
probed in detail with remarkable experimental control of system parameters. 1–3 Perhaps …

We revisit the problem of the double-quantum dots in side-dot configuration at finite
temperature, performing analytical calculations at zero temperature and at finite …
