AI 中文摘要
我们研究了弱反应和强相分离条件下化学活性液滴的尺寸波动。通过将确定性液滴生长的薄界面模型与基于涨落-耗散论证的随机噪声相结合,我们报告了理论与数值场模拟之间极好的定量一致性。最后,我们利用该模型推断控制液滴生长的有效非平衡势,并表明能够实现尺寸控制的活性反应会抑制成核。
英文摘要
We study size fluctuations of chemically active droplets in the regime of weak reactions and strong phase separation. By combining a thin-interface model for the deterministic droplet growth with stochastic noise based on fluctuation-dissipation arguments, we report excellent quantitative agreement between our theory and numerical field simulations. Finally, we use our model to infer the effective non-equilibrium potential that governs droplet growth, and show that active reactions that enable size control suppress nucleation.
