2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/19321We examine the favoured cluster structures for two new potentials, which both behave as monatomic model glass-formers in bulk. We find that the oscillations in the interatomic potential lead to global minima that are non-compact arrangements of linked 13-atom icosahedra. We find that the structural properties of the clusters correlate with the glass-forming propensities of the potentials, and with the fragilities of the corresponding supercooled liquids.9 pages, 7 figures; new section added and error in potential parameters correctedCondensed MatterAtomic and Molecular Clusterstext
