Stochastic rotor engine based on the electron shuttling mechanism — •Christopher W. Wächtler1, Philipp Strasberg2, and Gernot Schaller1 — 1Institute of Theoretical Physics, Berlin, Germany — 2Física Teòrica: Informació i Fenòmens Quàntics, Barcelona, Spain
The single electron shuttle is an example of a nano-scale system exhibiting a transition towards self-oscillation, where mechanical oscillations of a metallic grain are achieved by sequential electron tunnelling between the grain and two connecting leads. We theoretically investigate how one can use this shuttling mechanism to build a stochastic rotor engine which converts between chemical and mechanical work by applying a bias voltage between the two leads. Furthermore, we show that this rotor engine can also be used as a heat engine by applying a temperature bias between the electronic leads and the heat reservoir connected to the rotor. Besides the average thermodynamic quantities we additionally study the fluctuations of these quantities.
