Spinodal decomposition in a three-dimensional fluid model

Abstract

We study spinodal decomposition after a critical quench to finite temperature for a three-dimensional Langevin fluid model which includes full couplings between the order parameter and the currents. Our results agree with the expectation based on phenomenological considerations, namely, that the asymptotic growth exponent for this model is n=1, and, when compared to two-dimensional results for the same model, indicate that the dimensionality may be relevant in this problem.
