Lett. 109(20) (2012), DOI:https://doi.org/10.1103/PhysRevLett.109.203006DOI:https://doi.org/10.1103/PhysRevLett.109.203006http://hdl.handle.net/11603/19385We propose an experimental scheme to realize a nanoheat engine with a single ion. An Otto cycle may be implemented by confining the ion in a linear Paul trap with tapered geometry and coupling it to engineered laser reservoirs. The quantum efficiency at maximum power is analytically determined in various regimes. Moreover, Monte Carlo simulations of the engine are performed that demonstrate its feasibility and its ability to operate at a maximum efficiency of 30% under realistic conditions.6 pagesen-USThis item is likely protected under Title 17 of the U.S. Copyright Law.
