In agreement with earlier numerical simulations, we find that as $N\\to\\infty$, $D_f$ approaches zero as $1/\\ln^3N$, where $N$ is the average number of particles per correlation volume in the stable phase of the front. This behaviour of $D_f$ stems from the shape fluctuations at the very tip of the front, and is independent of the microscopic model.", "revisions": [ { "version": "v3", "updated": "2003-10-13T17:50:27.000Z" } ], "analyses": { "keywords": [ "diffusion coefficient", "asymptotic scaling", "fluctuating", "microscopic model", "average number" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
