- Abstract: We study a minimal quantum Otto heat engine, where the working medium
consists of an interacting few-body system in a harmonic trap. This allows us
to consider the interaction strength as an additional tunable parameter during
the work strokes. We calculate the figures of merit of this engine as a
function of the temperature and show clearly in which parameter regimes the
interactions assist in engine performance. We also study the finite time
dynamics and the subsequent trade-off between the efficiency and the power,
comparing the interaction enhanced cycle with the case where the system remains
scale-invariant.
