论文摘要
我们提出了在布朗多体系统中集体流动下与非平衡结构形成相关的力的基本分类。内部一体力场系统地分为与空间结构和耦合运动相关的贡献。我们证明,这两种贡献都可以在计算机模拟中直接获得,并提出了幂函数理论,该理论量化了所有类型的力量。我们的结论和方法与惯性系统(例如分子液体和颗粒培养基)的流动有关。
We present a fundamental classification of forces relevant in nonequilibrium structure formation under collective flow in Brownian many-body systems. The internal one-body force field is systematically split into contributions relevant for the spatial structure and for the coupled motion. We demonstrate that both contributions can be obtained straightforwardly in computer simulations, and present a power functional theory that describes all types of forces quantitatively. Our conclusions and methods are relevant for flow in inertial systems, such as molecular liquids and granular media.
