Abstract

The electronic transport of two quantum dots side‐coupled to a quantum wire is studied by means of the two impurity Anderson Hamiltonian. The conductance is found to be a superposition of a Fano and a Breit–Wigner resonances as a function of the Fermi energy, provided the gate voltages of the quantum dots are slightly different.
