Universal Coherence-Induced Power Losses of Quantum Heat Engines in Linear Response
Kay Brandner, Michael Bauer, Udo Seifert
We introduce a universal scheme to divide the power output of a periodically driven quantum heat engine into a classical contribution and one stemming solely from quantum coherence…
Optimal performance of periodically driven, stochastic heat engines under limited control
Michael Bauer, Kay Brandner, Udo Seifert
We consider the performance of periodically driven stochastic heat engines in the linear response regime. Reaching the theoretical bounds for efficiency and efficiency at maximum p…
Coherence-enhanced efficiency of feedback-driven quantum engines
Kay Brandner, Michael Bauer, Michael T. Schmid +1
A genuine feature of projective quantum measurements is that they inevitably alter the mean energy of the observed system if the measured quantity does not commute with the Hamilto…
Optimized finite-time information machine
Michael Bauer, Andre C. Barato, Udo Seifert
We analyze a periodic optimal finite-time two-state information-driven machine that extracts work from a single heat bath exploring imperfect measurements. Two models are considere…
Efficiency of a Brownian information machine
Michael Bauer, David Abreu, Udo Seifert
A Brownian information machine extracts work from a heat bath through a feedback process that exploits the information acquired in a measurement. For the paradigmatic case of a par…
