Rare gas clusters: Solids, liquids, slush, and magic numbers

摘要: Simulations by constant energy molecular dynamics have been performed for numerous clusters in the size range N=7–33. Detailed investigations conducted on portions of caloric curves which transition between rigid and nonrigid behavior occurs, to study N dependence solid–liquid phase change. Clusters several sizes display a coexistence forms, each with characteristic mean temperature, over well‐defined region, as had observed Ar13 cluster. Within high temperature form is solid‐like low behaves liquid‐like fashion. The state these take two‐valued forms when averages are calculated two ‘‘phases’’ separately; branches smooth extensions from single regions. other do not this clear phases, but appear pass through ‘‘slush‐like’’ du...
