- Abstract: We use fast periodic control to realize finite-time Otto cycles exhibiting
quantum advantage. Such periodic modulation of the working medium - bath
interaction Hamiltonian during the thermalization strokes can give rise to
non-Markovian anti-Zeno dynamics, and corresponding reduction in the
thermalization times. Faster thermalization can in turn significantly enhance
the power output in engines, or equivalently, the rate of refrigeration in
refrigerators. This improvement in performance of dynamically controlled Otto
thermal machines arises due to the time-energy uncertainty relation of quantum
mechanics.
