Linear conductance through parallel coupled quantum dots

We study the electronic transport through two parallel coupled quantum dots (QDs), employing the X-boson treatment for the single impurity Anderson model. We compute the linear conductance (LC) and transmission coefficient for different regimes of the system, as function of the QDs energy; our results show a suppression of the linear conductance at low temperatures; when the coupling between the QDs is significant, a drop in the transmission coefficient is evident, at the energy value of the side-coupled QD. We also obtain the temperature dependence of the LC, for different hybridizations between the QDs and the energy of one of them. Our results are consistent with those obtained by other theoretical treatments and recovers what is expected when the coupling between the QDs is weak.
