EARLY-STAGE SCALING IN PHASE ORDERING KINETICS

A global analysis of the scaling behavior of a system with a scalar order parameter quenched to zero temperature is obtained by numerical simulation of the Ginzburg-Landau equation with conserved and nonconserved order parameters. A rich structure emerges, characterized by early and asymptotic scaling regimes, separated by a crossover. The interplay among different dynamical behaviors is investigated by varying the parameters of the quench and can be interpreted as being due to the competition of different dynamical fixed points. © 1995 The American Physical Society.
