AI 中文摘要
我们研究被限制在由两块图案化壁构成的狭缝中的流体的平衡相行为。对壁施加剪切会使流体受到阻碍，这源于毛细管凝聚与界面离域之间的竞争，迫使形成具有不同钉扎特性的桥接相。这会产生异常丰富的相图，呈现一级和连续相变，且对狭缝宽度和剪切作用极为敏感。广义开尔文方程确定相边界，而桥接相以大关联长度为特征，我们使用微观密度泛函模型对这一特征的预测进行了检验。
英文摘要
We study the equilibrium phase behavior of a fluid confined in a slit made from two patterned walls. Shearing the walls frustrates the fluid, due to a competition between capillary condensation and interface delocalization, forcing the formation of bridging phases with different pinning properties. This leads to an unusually rich phase diagram, displaying first-order and continuous phase transitions, depending sensitively on the slit width and shear. Generalized Kelvin equations determine the phase boundaries, while the bridging phases are characterized by large correlation lengths, predictions for which are tested using a microscopic density functional model.
