Round 1

Reviewer 1 Report

The authors consider a somewhat exotic generalization of the standard theory of quantum gases, such as Bose-Einstein condensates, including form factors and multipole interactions among other things. While I am not sure about the physical motivation and potential impact of this approach, the article is clear and well-written and the mathematical analysis seems sound. Results are discussed in detail. 

In summary, I cannot reject the publication of this paper and I hope that it might be of interest for some researchers.

Reviewer 2 Report

The manuscript deals with unusual, but interesting physics of quantum gases. On the hand dipole, quadrupole and octupole interactions in the mean-field Gross–Pitaevskii are considered. On the other the focus is on the impact of form factors. In both cases, however, the major deficiency of the manuscript is the lack of any connection to experiments. Thus, the authors should review

1) In which context appear apart from dipolar interactions also quadrupole and octupole interactions in the realm of ultracold quantum gases? It would be preferable if you could mention explicitly examples of quantum gases with their respective dipole, quadrupole and octupole interaction strength.

2) Where do form factors play an experimental role? In which experiments are they measured and how they are modelled in order to describe the measurements.

Furthermore, the manuscript contains partially superfluous theoretical material, which distracts the reader from the main message. One example is the excursion into quantum field theory in the introduction. Here various correct statements are made, but their context to the different types of interactions and form factors, respectively, is not given. And a third major criticism is that the English language of the manuscript should be polished.

Thus, in conclusion, the manuscript needs a severe revision along the line „less theory – more experiment“ in order to underline the motivation for the work.
