Single-electron transistor strongly coupled to vibrations: counting statistics and fluctuation theorem

摘要: Using a simple quantum master equation approach, we calculate the full counting statistics of single-electron transistor strongly coupled to vibrations. The contains both integrated particle and energy currents associated with transferred electrons phonons. A universal as well an effective fluctuation theorem are derived for general case where various reservoir temperatures chemical potentials different. first relates entropy production generated in junction, while second reveals internal information system. model recovers Franck–Condon blockade, potential applications non-invasive molecular spectroscopy discussed.
