37. We have derived the Hamiltonian 3 in the scattering picture of transport through the detector. On the level of observables such as the average current and the noise, the scattering picture of transport and the tunneling picture of transport are equivalent in the tunneling regime. The validity range of the scattering picture, however, also extends to the regime of an open QPC.
