We analyze an autonomous micro-engine as a closed quantum mechanical system, including the work it performs and the fuel it consumes. Our model system shows by example that it is possible to transfer energy steadily and spontaneously between fast and slow degrees of freedom, in analogy to the way combustion engines convert chemical energy into work. Having shown this possibility, we observe close analogies between the closed-system quantum dynamics of our micro-engine and the First and Second Law of Thermodynamics. From these analogies we deduce a generalized formulation of thermodynamics that remains valid on the micro-scale.

Autonomous conversion of particle-exchange to quantum self-oscillations
A quantum-dot particle-exchange machine coupled to a mechanical resonator produces sustained self-oscillations in the slow-transport regime, detectable in the electrical current, and only in the heater regime.
