List "5 most recent preprints citing Kwant" on the entry page
This, or something similar could be added to the entry page to show that Kwant is currently in use by various groups. This idea was brought up by Chagaan and I think it's a good one. Perhaps it would be even better to also provide a list of all the citing papers, e.g. like this:
5 most recent preprints citing Kwant: (1) ... (2) ... (3) ... (4) ... (5) ... [view all the 123 articles that cite the Kwant paper]
Perhaps a cronjob that triggers arxiv's full-text-search for "kwant groth" (the name of the first author) and processes the results would do the trick. I'm not sure, however, how to best integrate this with the otherwise static website. @anton-akhmerov, @jbweston, any ideas?
