Abstract: | By measuring the distribution function of the end-to-end distance, we find that strongly shaken bead chains exhibit many properties,
such as the rigid-rod-to-Gaussian chain transition, scaling, fast drop of loop formation probability in the short-chain regime,
and enhancement of loop formation probability for kinked chains, of long-chain polymers. Though there is difference in local
details between our chains and the worm-like chains, our results are consistent with recent calculations based on the worm-like
chain model in many respects. |
