Single ion heat engine at maximum Efficiency at maximum power

摘要

We propose a concrete experimental scheme to realize a quantum heat engine with a single ion as a working gas. We confine the ion in a modified linear Paul trap and implement an Otto cycle by coupling it to engineered laser baths. We analytically determine the efficiency at maximum power in various regimes. We perform extensive Monte Carlo simulations of the engine to demonstrate its feasibility. We further show that it can run at maximum efficiency.
