Otto Engine for the q-State Clock Model
Round 1
Reviewer 1 Report
The paper describes an Otto engine cycle across a phase transition. The model analysed is based on the q-state clock model which allows to interpolate from the 2-D Ising model to more complex interactions.
The results are interesting. Thinking about the cycle; optimal work could be achieved if the work required fro the cold compression could be decreased by choosing a phase which minimizes the cost of compression. The opposite should work for the hot expansion where the phase should be chosen to maximize the output work.

Reviewer 2 Report
The paper is interesting since the view of point of modeling. However, particularly with the results, I would like to know, how can the authors validate the data obtained? On the paper there is not a comparison with previous studies. Also, what is the main contribution of your paper? Is not clear. Results indicates that in q = 4 the total work extraction of the cycle is highest and for q = 2, there is the lowest. But, what indicates this result? Is necessary strengthen your conclusions.
