Non-algebraic domain growth for phase ordering d in a random field

Discusses the three-stage numerical exposition of the effects of quenched disorder on phase ordering dynamics. The authors study the effects of random fields on domain growth. The numerical results indicate that the domain growth law is logarithmic for both the cases with non-conserve and conserved order parameter. This is compatible with theoretical expectations. They also study the dynamical scaling of the structure factor for both the non-conserved and conserved cases
