Abstract:

Electronic transport through a system of two quantum dots coupled to external leads is considered theoretically. The dots are assumed to be in the Kondo regime, and the infinite-U mean-field slave-boson approach is used to obtain basic transport characteristics. Density of states and electron transmission probability in the Kondo regime are considered and calculated numerically. Both quantities are shown to exhibit features that are typical of the Dicke resonance.
