Data associated to the publication "Breakdown of the scattering picture for charge transfer in a quantum dot"

The publication deals with the electron transport through a quantum dot. The analysis of charge fluctuations in a mesoscopic device can shed light on the fundamental question of whether or not a single-particle scattering picture of electron transport is appropriate, even in the presence of Coulomb interaction.

It has been shown on general grounds that mapping the interacting system onto a single-particle description is subject to strict constraints on the charge-transfer statistics. These constraints can be formulated in terms of a sign rule for the factorial cumulants of the full counting statistics. In the paper, we report on the experimental observation of a sign-rule violation in a most elementary model system, i.e. a single-level quantum dot.
