一个自由放松的polymer记得它是如何被拉直的

A freely relaxing polymer remembers how it was straightened

摘要:

本文主要从最长弛豫时间的角度讨论了初始直链半柔性聚合物的弛豫。生物学相关的非平衡动力学在较短的时间内是比较少的理解,部分原因是“最初的直线”可以实现多种方式。结合布朗动力学模拟和系统理论,我们演示了不同的实验准备如何产生特定的短时间和普遍的长时间动态。我们还讨论了边界效应和发病的拉伸线圈过渡。

英文摘要:

The relaxation of initially straight semiflexible polymers has been discussed mainly with respect to the longest relaxation time. The biologically relevant non-equilibrium dynamics on shorter times is comparatively poorly understood, partly because "initially straight" can be realized in manifold ways. Combining Brownian dynamics simulations and systematic theory, we demonstrate how different experimental preparations give rise to specific short-time and universal long-time dynamics. We also discuss boundary effects and the onset of the stretch--coil transition.
