高分子在拥挤硬环境中的持留长度重整化

Persistence-Length Renormalization of Polymers in a Crowded Environment of Hard Disks

Sebastian Schöbl, Sebastian Sturm, Wolfhard Janke, Klaus Kroy

摘要:

半柔性聚合物最显著的特性是它的持续长度,定义为沿其轮廓的切线相关的衰减长度。使用一个有效的随机增长算法的样品嵌入淬火的二维硬盘流体中的聚合物,我们发现明显的蠕虫状链统计与重正化的持久性长度。我们确定了一个普遍形式的无序重整化,这表明自己作为一个定量的分子拥挤的措施。

英文摘要:

The most conspicuous property of a semiflexible polymer is its persistence length, defined as the decay length of tangent correlations along its contour. Using an efficient stochastic growth algorithm to sample polymers embedded in a quenched two-dimensional hard-disk fluid, we find apparent wormlike chain statistics with a renormalized persistence length. We identify a universal form of the disorder renormalization that suggests itself as a quantitative measure of molecular crowding.
