Theta-polymers in crowded media under the stretching force
arXiv:1009.4616 · doi:10.1016/j.cpc.2010.12.022
Abstract
We study the peculiarities of stretching of globular polymer macromolecules in a disordered (crowded) environment, using the model of self-attracting self-avoiding walks on site-diluted percolative lattices in space dimensions d=3. Applying the pruned-enriched Rosenbluth chain-growth method (PERM), we construct the phase diagram of collapsed-extended state coexistence when varying temperature and stretching force. The change in shape characteristics of globular polymers under stretching is analyzed as well.
