Comment on "Deterministic equations of motion and phase ordering dynamics".


Zheng [Phys. Rev. E 61, 153 (2000)] claims that phase ordering dynamics in the microcanonical phi(4) model displays unusual scaling laws. We show here, performing more careful numerical investigations, that Zheng only observed transient dynamics mostly due to the corrections to scaling introduced by lattice effects, and that Ising-like (model A) phase ordering actually takes place at late times. Moreover, we argue that energy conservation manifests itself in different corrections to scaling.
