Preasymptotic multiscaling in the phase-ordering dynamics of the kinetic Ising model
arXiv:cond-mat/9906094 · doi:10.1209/epl/i1999-00366-3
Abstract
The evolution of the structure factor is studied during the phase-ordering dynamics of the kinetic Ising model with conserved order parameter. A preasymptotic multiscaling regime is found as in the solution of the Cahn-Hilliard-Cook equation, revealing that the late stage of phase-ordering is always approached through a crossover from multiscaling to standard scaling, independently from the nature of the microscopic dynamics.
