- Abstract: Finite-time quantum heat engines are of practical relevance as they can
generate finite-power, distinguishing them from ideal quasistatic engines
typically used for theoretical purposes. However, these engines encounter
energy losses due to quantum friction, which is particularly pronounced in
many-body systems with non-trivial coherences in their density operator.
Strategies such as shortcuts to adiabaticity and fast routes to thermalization
have been developed although the associated cost requirements remain uncertain.
In this study, we theoretically investigate the finite-time operation of a
trapped-atom Otto engine with light-induced dipole-dipole interactions and
projection measurements in one of the isochoric processes. The investigation
reveals that appropriate control of dipole-dipole interactions of the working
medium prompts engine operation upon interacting with the hot reservoir, while
projection measurements and adjustment of the unitary driving protocols
effectively reduce quantum friction to enhance finite-time engine performance
compared to non-interacting and quasi-static counterparts. This setup presents
a compelling avenue for further investigation of finite-time many-body quantum
heat engines and provides an opportunity to explore the full potential of
photon-mediated dipole-dipole interactions in their operations.
