Reviewer #1: The authors have improved the discussion concerned the impact of their fidings and I now recommend their manuscript to be published at AOP.
Reviewer #2: The authors have done a good job in the revision. Now I recommend the article for publication.
Reviewer #3: I still believe that the paper should discuss in more depth the issues I raised in the first report. Nonetheless, the answers provided are satisfactory. The paper can now be published, in my opinion.
Reviewer #1: The manuscript deals with an important aspect for a particle constrained on an (N − 1)-dimensional hypersphere: a proper angular momentum algebra. In short, the authors show that it must take into account both the orbital angular momentum and the spin-curvature coupling, in contrast to previous works in the field. Themanuscript is sound and I recommend publication once the authors have revised their manuscript in accordance with the following comment:
1- The conclusions cannot be a brief description of what the Authors were done theoretically in the previous sections. The impact of their findings have to be well discussed and possible physical applications should be shortly discussed there.
After this implementation, I believe the manuscript will be more appealing to a general audience.
Reviewer #2: The article investigates quantization of the motion of a particle confined to a hypersphere in N-dimensional Euclidean space. The subject is interesting and the paper complements previous results of the literature. The calculations seem to becorrect and the main result makes physical sense. The article may be accepted for publication after some revision. I think it would be educative that the authors include a comment on the N=3 case. My main recommendation concerns the use of the English language. A major revision of grammar and spelling is mandatory.
Reviewer #3: This paper deals with an interesting and timely topic, even though it is a basic one, hence something one would like to have well under control and understood. And that is precisely my concern here.
I mean that the paper might be worth publishing only if it adds clarity to this basic topic. Henceforth, the authors (besidesbeing much more careful with a somehow sloppy English...) have to make an extra effort to:
- discuss in all details how this approach relates to the standard covariant derivative in the presence of spin, because, after all, their Pi_i is a standard derivative, and their p_i is a covariant derivative, henceforth...
- ... they have to show what is the link between their 'gauge field' and the standard spin connection that appears when dealing with fields with spin.
- Furthermore, it is well known in classical field theory, that it is precisely the procedure of imposing constraints that leads to the very same idea of gauge fields. Now, perhaps the authors, or some of them, have already discussed that in some of their previous papers, reported in the Reference. Nonetheless, for completeness of the discussion, to comply with the style and scope of Annals of Physics (that is not a letter journal), and since they claim to be amending text books (like their refs  and ), a substantial and detailed discussion of this and other general points, is sorely missing...
- ... indeed, they should also fully clarify that the procedure here is made of two separate steps, one for spinless and one for 'spinfull' quantities, and that the literature is, perhaps, not so careful in presenting the issue, but surely this is not entirely missed by those authors.
Overall, at the classical level one indeed has the spin connection already, and that is the classical gauge field that takes care of the spin. One then needs to be careful in defining the proper momenta to be quantized, and this paper comes in hand, also because it is linking that to the quantization in a constrained system, and these days (see, eg., graphene physics) it is nice to have control of that. On the other hand, especially on matters that are well established and discussed in text-books, one needs to be crystal clear, refer to all known results, and explain every single step and the context very clearly. The latter is missing in the present version.
