论文摘要
通过广义兰格文列方程（GLE）绘制的胶体粒子绘制的扩散轨迹可唤起静态聚合物构型的随机分形。本文提出了一个类似静态的GLE样描述，该描述能够生成与一维链结构沿静态波动 - 响应关系（FRR）满足静态波动 - 响应关系（FRR）的噪声，而不是沿时间坐标。一个显着的观点是静态和动力学Gles之间FRR公式的定性差异和相似性。在静态FRR的指导下，我们根据随机能量学和稳态波动定理进一步提出类似的论点。
A diffusive trajectory drawn by the generalized Langevin equation (GLE) for a colloidal particle evokes a random fractal of a static polymer configuration. This article proposes a static GLE-like description that enables the generation of a single configuration of a polymer chain with the noise formulated to satisfy the static fluctuation-response relation (FRR) along a one-dimensional chain structure but not along a temporal coordinate. A remarkable point is qualitative differences and similarities in the FRR formulation between the static and the dynamical GLEs. Guided by the static FRR, we further make analogous arguments in the light of stochastic energetics and the steady-state fluctuation theorem.
