We then examine, for a binary mixture of soft discs in two dimensions, the correlation between the spatial distribution of propensity and that of two localmeasures of configuration structure: the local composition and local free volume. While the small particles dominate the high propensity population,we find no strong correlation between either the local composition or the local free volume and the propensity. It is argued that this is a generic failure of purely local structural measures to capture the inherently non-local character of collective behaviour.", "revisions": [ { "version": "v2", "updated": "2009-01-27T02:17:51.000Z" } ], "analyses": { "keywords": [ "supercooled liquid", "local free volume", "local composition", "relationship", "dynamic propensity distribution" ], "tags": [ "journal article" ], "publication": { "journal": "Journal of Physics Condensed Matter", "year": 2005, "month": "Dec", "volume": 17, "number": 49 }, "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2005JPCM...17S4025W" } } }
