EnglishWe propose a layout for a tunable mesoscopic cavity that allows to probe the conductance and noise properties of direct transmission channels (``noiseless scattering states''). Our numerical simulations demonstrate how the variation of different gate voltages in the cavity leads to characteristic signatures of such non-universal processes. Using realistic assumptions about scattering in two-dimensional heterostructures, our proposed layout should define a viable protocol for an experimental realization.
