The out-of-equilibrium transport properties of a double quantum dot system in the Kondo regime are studied theoretically by means of a two-impurity Anderson Hamiltonian with interimpurity hopping. The Hamiltonian, formulated in slave-boson language, is solved by means of a generalization of the noncrossing approximation (NCA) to the present problem. We provide benchmark calculations of the predictions of the NCA for the linear and nonlinear transport properties of coupled quantum dots in the… Expand
Shot noise in strongly correlated double quantum dots
We have investigated theoretically the shot noise of strongly correlated double quantum dot systems in the regime where the Kondo effect and the interdot antiferromagnetic exchange do compete. OurExpand
Correlated electrons and transport in a quantum point contact and in a double-quantum-dot system
A problem of electronic correlations is considered for two specific mesoscopic systems: the quantum point contact (QPC) and the double quantum dot (2QD) system. The systems are described using aExpand
Conductance of a double quantum dot system in the Kondo regime in the presence of inter-dot coupling and channel mixing effects

Two-impurity anderson model for the transport through two quantum dots coupled via a quantum wire
We study the problem of transport through two quantum dots coupled via a finite-length quantum wire. In the limit where each dot acts essentially as a localized Kondo impurity, the geometry allows usExpand

Effects of van Hove Singularities on Transport of Quantum Dot Systems in Kondo Regime
In the present paper, we study the effect of van Hove singularities of conduction electron on the transport of a single quantum dot system in the Kondo regime. By using both the equation-of-motionExpand
Kondo Effect Versus Magnetic Coupling in Indirectly Coupled Double Quantum Dots
We theoretically investigate a device consisting of two quantum dots (QDs) side-coupled to a quantum wire which has many physical ingredients of an artificial heavy fermion system. An extraExpand
