Frontera Beccaria, CarlosVives i Santa-Eulàlia, EduardCastán i Vidal, Maria TeresaPlanes Vila, Antoni2009-12-232009-12-2319960163-1829https://hdl.handle.net/2445/10449In a recent paper [Phys. Rev. B 50, 3477 (1994)], P. Fratzl and O. Penrose present the results of the Monte Carlo simulation of the spinodal decomposition problem (phase separation) using the vacancy dynamics mechanism. They observe that the t1/3 growth regime is reached faster than when using the standard Kawasaki dynamics. In this Comment we provide a simple explanation for the phenomenon based on the role of interface diffusion, which they claim is irrelevant for the observed behavior.4 p.application/pdfeng(c) The American Physical Society, 1996Termodinàmica estadísticaMatèria condensadaTransformacions de fase (Física estadística)Statistical thermodynamicsCondensed matterPhase transformations (Statistical physics)Comment on "Kinetics of spinodal decomposition in the ising model with vacancy diffusion"info:eu-repo/semantics/article112058info:eu-repo/semantics/openAccess
