We study the zero-bias conductance through the system of two quantum dots, one of which
is embedded directly between the source and drain electrodes, while the second dot is side …

Orbital Kondo effect in a system of two single-level quantum dots attached to external
electron reservoirs is considered theoretically. The dots are coupled via direct hopping term …

In the present work we apply the atomic approach to the single-impurity Anderson model
(SIAM). A general formulation of this approach, that can be applied both to the impurity and …

We study the thermopower and thermal conductivity of a gate-defined quantum dot, with a
very strong Coulomb repulsion inside the dot, employing the X-boson approach for the …

We study thermoelectric transport properties through a gate defined T-coupled quantum dot,
describing the system at base with the single impurity Anderson model (SIAM), whose …

We study the thermopower, thermal conductance, electric conductance and the
thermoelectric figure of merit for a gate-defined T-shaped single quantum dot (QD). The QD …

We theoretically investigate the spin-resolved local density of states (SR-LDOS) of a spin-
polarized two-dimensional electron gas in the presence of a Kondo adatom and a scanning …

We consider the cumulant expansion of the periodic Anderson model (PAM) in the case of a
finite electronic correlation U, employing the hybridization as perturbation, and obtain a …

In this work we consider the Coqblin–Schrieffer model when the spin is S= 1/2. The atomic
solution has eight states: four conduction and two localized states, and we can then …

With the recent development of the nanoscopic technology, the impurity Anderson model
(AIM) was experimentally realized in quantum dot devices, and there is renewed interest in …
