Finite size scaling leads us to expect that the vanishing of the diffusion coefficient as \\xi^{-1} for \\xi<>L. We show that this is not strictlytrue. There is a logarthmic scaling violation. We construct a Kawasaki like scaling function that connects the thermodynamic regime to the extreme critical (\\xi>>L) regime.", "revisions": [ { "version": "v1", "updated": "2003-07-03T08:09:33.000Z" } ], "analyses": { "keywords": [ "scaling function", "critical fluid", "finite geometry", "long wavelength diffusion coefficient", "parallel plates" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
