Crossover from multiscaling to standard scaling in systems with conserved scalar order parameter

The phase-ordering dynamics with conserved scalar order parameter is studied simulating the Cahn-Hilliard equation and the kinetic Ising model. In both cases a preasymptotic multiscaling regime is found 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.
