Fluctuation theorem for a single electron transistor strongly coupled to
vibrations
   [PDF]

Gernot Schaller, Thilo Krause, Tobias Brandes, Massimiliano Esposito
Using a simple quantum master equation approach, we calculate the Full Counting Statistics of a single electron transistor strongly coupled to vibrations. The Full Counting Statistics contains both the statistics of integrated particle and energy currents associated to the transferred electrons and phonons. A universal fluctuation theorem, as well as effective fluctuation theorems are derived for the general case where the various reservoirs temperatures and chemical potentials are different. The first relates to the entropy production generated in the junction while the second may be used as an electronic thermometer. The model recovers Franck-Condon blockade and potential applications to non-invasive molecular spectroscopy are discussed.
