Universal Coherence-Induced Power Losses of Quantum Heat Engines in Linear Response
Universal Coherence-Induced Power Losses of Quantum Heat Engines in Linear Response
We identify a universal indicator for the impact of coherence on periodically driven quantum devices by dividing their power output into a classical contribution and one stemming solely from superpositions. Specializing to Lindblad dynamics and small driving amplitudes, we derive general upper bounds on both the coherent and the total …
