AbstractWe讨论了一个分层协议的可行性,其中的描述和预测的吸附流体在密闭系统中的介观尺度是通过使用从原始分子模拟数据得到的界面电位。从一个平面基板上的流体的界面的微观描述开始,我们试图提取所需的最小信息,以预测该流体的行为在较大的长度尺度从粗粒表面哈密顿。这个过程的关键评估取决于有争议的润湿行为方面,更普遍的是对热力学系统的亚稳性和不稳定性的意义。
AbstractWe discuss the feasibility of a hierarchical protocol whereby the description and prediction of adsorbed fluids in confined systems at the mesoscopic scale is achieved by use of interface potentials that are obtained from raw molecular simulation data. Starting from a microscopic description of a fluid’s interface on a flat substrate, we attempt to extract the minimum information that is required in order to predict the behavior of that fluid at larger length scales from coarse grained surface Hamiltonians. A critical assessment of this procedure hinges on controversial aspects of wetting behavior and more generally on the meaning of metastability and instability of thermodynamic systems.
