论文摘要
为了深入了解流体界面，有必要确定有意义的粗粒长度，因为后者缺乏适当的统计机械定义，将内在波动与毛细血管的固有波动分开。在这里，在无监督的学习技术的帮助下，我们根据流体的局部密度引入了一个新的长度量表。该长度尺度遵循的缩放定律，该定律定律比接近临界点时的散装相关长度更温和。这允许区分相关和不相关的毛细血管与内在波动的方案。
To reach a deeper understanding of fluid interfaces it is necessary to identify a meaningful coarse-graining length that separates intrinsic fluctuations from capillary ones, given the lack of a proper statistical mechanical definition of the latter. Here, with the help of unsupervised learning techniques, we introduce a new length scale based on the local density of the fluid. This length scale follows a scaling law that diverges more mildly than the bulk correlation length upon approaching the critical point. This allows to distinguish regimes of correlated and uncorrelated capillary waves from that of intrinsic fluctuations.
