Persistence-Length Renormalization of Polymers in a Crowded Environment of Hard Disks
arXiv:1410.5960 · doi:10.1103/PhysRevLett.113.238302
Abstract
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.
