Spinodal decomposition similarity property

The latter mechanism remains effective up to the end, however, the structure characteristics must finally change as the similarity property cannot be maintained. The very end is a macroscopic phase separation, as shown for example in Fig. 3.37, and clearly, the final structure is always of the same type independent of whether phase separation has started by spinodal decomposition or by nucleation and growth. 

Our results suggest that the above dynamics can be viewed as an evolution in a stochastic potential whose qualitative aspect depends on time at the beginning it is similar to the deterministic potential, but subsequently it deforms (the deformation depending on the volume and initial conditions) and develops a second minimum. This minimum is responsible for the transient "stabilization" of the maximum of P(X,t) before the inflexion point. As the tunneling towards the other minimum on the stable attractor goes on, the first minimum disapears and the asymptotic form of the stochastic potential, determining the stationary properties of P(X,t), reduces again to the deterministic one. This phenomenon of "phase transition in time" is somewhat reminiscent of spinodal decomposition.
