标题： Bulk condensation by an active interface

摘要： 我们通过机械详细模拟支持的实验，展示了由少量可定向运动的颗粒组成的系统能够使硬珠流体发生体相气液冷凝的现象，这些颗粒自组装成移动的极化单层。 在准一维几何结构中，两个相反排列的此类单层使冷凝的非运动成分固定不动。 我们通过一种自然具有非互易性的连续理论来解释我们的观察，该理论具有典型的Cahn-Hilliard结构，其预测趋势与堆积分数相关的观察结果一致。 显示英文摘要

摘要： We present experiments, supported by mechanically detailed simulations, establishing bulk vapor-liquid condensation of a hard-bead fluid by a tiny population of orientable motile grains that self-assembles into a moving polarized monolayer. In a quasi-1D geometry two such layers, oppositely aligned, immobilize the condensed non-motile component. We account for our observations through a continuum theory with a naturally non-reciprocal Cahn-Hilliard structure, whose predicted trends as a function of packing fraction are consistent with our observations.
