– We consider the diffusive motion of a localized knot along a linear polymer chain. In particular, we derive the mean diffusion time of the knot before it escapes from the chain once it gets close to one of the chain ends. Self-reptation of the entire chain between either end and the knot position, during which the knot is provided with free volume, leads to an L scaling of diffusion time; for sufficiently long chains, subdiffusion will enhance this time even more. Conversely, we propose local… CONTINUE READING
