Transport through strongly correlated triple quantum dot

Abstract

Strong electron correlations are discussed for the three capacitively coupled quantum dots, each of which is connected to a separate pair of electrodes. The finite-$U$ mean field slave boson approach is used. The analysis is carried out for both repulsive and attractive intra- and inter-dot interactions. Depending on the ratio and the sign of interaction parameters and occupation, either charge ordered states or different spin, spin-charge and charge Kondo resonances arise.
