Scientists comment on papers by writing papers. For a paper that just appeared, wait a year or so, and check Google Scholar for papers that cite this paper. Check again every few months. If you know physicists with an interest in this field, you can ask them if they’ve seen the paper and what they think of it. If they have an opinion they’ll probably share it with you freely, but they won’t write it down anywhere.
