Coherent and incoherent transport through T-shaped double quantum dots

We investigate the measurement induced dephasing of the Fano effect in the electronic transport through a double quantum dot mesoscopic interferometer coupled to a charge detector. The current and the differential conductance are computed within the Keldysh formalism, taking into account of the inelastic processes due to the dot–detector interaction. We show that the visibility of the Fano lineshape is reduced by applying a finite bias on the charge detector.
