Abstract
A procedure to find optimal regimes for quantum thermal engines (QTMs) is described and demonstrated. The QTMs are modelled as the periodically-driven non-equilibrium steady states of open quantum systems, whose dynamics is approximated in this work with Markovian master equations. The action of the external agent, and the couplings to the heat reservoirs can be modulated with control functions, and it is the time-dependent shape of these control functions the object of optimisation. Those functions can be freely parameterised, which permits to constrain the solutions according to experimental or physical requirements.
Author indications on fulfilling journal expectations
- Provide a novel and synergetic link between different research areas.
- Open a new pathway in an existing or a new research direction, with clear potential for multi-pronged follow-up work
- Detail a groundbreaking theoretical/experimental/computational discovery
- Present a breakthrough on a previously-identified and long-standing research stumbling block
Author comments upon resubmission
I wish to resubmit my article, that I hope has improved thanks to the suggestions of the referees.
Yours, Alberto Castro.
List of changes
* I have rewritten the introduction, clarifying the novelty of the work as suggested by the referees.
* I have included a paragraph explaining the computational complexity of the model.
* I have added an appendix, explaining how fluctuations can be included in the formalism.
* Other minor edits and improvements, suggested by the referees, or found by myself.

Report
I do not believe that the author has sufficiently responded to all the comments of my original report. For publication, they would have to thoroughly address all these points (in particular the question of novelty). I continue to recommend a revision of the manuscript.
