Reformulation of quantum noise: when indistinguishable becomes distinguishable?
In this work, quantum noise is reformulated taking into account the finite size of (normalizable) wave functions associated to electrons. We consider two-particle scattering with tunneling and exchange. This reformulation provides a richer phenomenology compared to timeindependent approaches, such as the Landauer-Buttiker formalism. It is proved that, depending on the scenario, the noise associated to identical electrons may behave as the one for distinguishable particles. In addition, it is showed that new contributions to the quantum noise appear.
