论文摘要
我们研究了由均匀外部电场驱动的电解质的随机动力学，尽管存在Debye筛选，但表明它表现出通用的尺度不变性。产生的远距离相关性引起了casimir样波动引起的力在局限离子的中性边界之间的力。该力由外部电场控制，与其他远距离波动引起的力不同，它可以具有吸引力和排斥性。这项工作强调了电解质中非平衡相关性的重要性，并显示了它们如何用于调节大分离处未充电的生物或合成结构之间的相互作用。
We study the stochastic dynamics of an electrolyte driven by a uniform external electric field and show that it exhibits generic scale invariance despite the presence of Debye screening. The resulting long-range correlations give rise to a Casimir-like fluctuation-induced force between neutral boundaries that confine the ions; this force is controlled by the external electric field, and it can be both attractive and repulsive with similar boundary conditions, unlike other long-range fluctuation-induced forces. This work highlights the importance of nonequilibrium correlations in electrolytes and shows how they can be used to tune interactions between uncharged biological or synthetic structures at large separations.
