Title:
Does shot noise measure always the quasiparticle charge?
Speaker:
Abstract:
We demonstrate that the Fano factor of partitioned shot noise (F=1 for integers), stemming from either weakly backscattered partitioned charges (by a QPC), purely from neutral modes, or both effects, depends only on the bulk filling and not on the structure (and conductance) of the edge modes or the filling inside the QPC constriction.
