论文摘要
我们证明了三个确切的总和规则，这些规则将活性的布朗颗粒的极化与它们的一身电流相关联：（i）总的极化消失，但前提是在边界上没有净通量，（ii）在任何平面壁上，极化是由散装电流的大小确定的，而（iii）（iii）的总界面差异是由相位差异的整体差异确定的。该结果排除了总界面极化对活动体积共存的影响，并质疑界面与散装的拟议耦合。
We prove three exact sum rules that relate the polarization of active Brownian particles to their one-body current: (i) The total polarization vanishes, provided that there is no net flux through the boundaries, (ii) at any planar wall the polarization is determined by the magnitude of the bulk current, and (iii) the total interface polarization between phase-separated fluid states is rigorously determined by the gas-liquid current difference. This result precludes the influence of the total interface polarization on active bulk coexistence and questions the proposed coupling of interface to bulk.
