These motifs, however, occupy an identical portion of space and bear identical first-order topological signatures as measured by persistent homology. Here we present a novel method based on k-fold covers that unambiguously distinguishes between these patterns. Moreover, our approach provides topological evidence that the FCC motif is the more stable of the two in the context of evolving experimental sphere packings during the transition from disordered to an ordered state. We conclude that our approach can be generalised to distinguish between various Barlow stackings manifested in minerals and metals."}],"volume":17,"file_date_updated":"2023-10-03T09:21:42Z","date_created":"2021-10-31T23:01:30Z","language":[{"iso":"eng"}],"publication":"Soft Matter","publication_status":"published","scopus_import":"1","_id":"10204","oa":1}
