dc.description.abstractWe investigate the nonequilibrium transport properties of a coupled quantum dot system connected in parallel to two leads, including electron-vibron interaction. It is known that in the absence of interaction the system supports a bound state in the continuum. This state is revealed as a Fano antiresonance in the transmission when the energy levels of the dots are detuned. Using the Keldysh nonequilibrium Green's function formalism, we find that the occurrence of the Fano antiresonance arises even if the electronvibration interaction is taken into account. We also examine the impact of the coupling to the leads in the linear response of the system. We conclude that the existence of bound states in the continuum in coupled quantum dot systems is a robust phenomenon, opening the possibility of its observation in experiments.
