Abstract

We develop a theory for the full counting statistics (FCS) for a class of nano-electromechanical systems (NEMS), describable by a Markovian generalized master equation. The theory is applied to two specific examples of current interest: vibrating C60-molecules and quantum shuttles. We report a numerical evaluation of the first three cumulants for the C60 setup; for the quantum shuttle we use the third cumulant to substantiate that the giant enhancement in noise observed at the shuttling transition is due to a slow switching between two competing conduction channels. Especially the last example illustrates the power of the FCS.
