## Abstract

We undertake a detailed numerical study of the {\\it Active Model B} proposed by Wittkowski et al. \[Nature Comm. {\\bf 5}, 4351 (2014)\]. We find that the introduction of activity has a drastic effect on the ordering kinetics. First, the domain growth law shows a crossover from the usual Lifshitz-Slyozov growth law for phase separation ($L \\sim t^{1/3}$, where $t$ is the time) to a novel growth law ($L \\sim t^{1/4}$) at late times. Second, the correlation function exhibits dynamical scaling for a given activity strength $\\lambda$, but the scaling function depends on $\\lambda$.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
