Abstract
We study the translocation of a polymer through a nanopore by means of Langevin dynamics simulations. For different driving forces F driving we find different power-law scaling behavior for the polymer translocation time τ trans as a function of the degree of polymerization N. If F driving is small the polymer stays in or near equilibrium during translocation and the observed behavior is consistent with predictions from equilibrium theory. For large F driving the polymer is driven far out of equilibrium. In this case, we observe a linear relation between τ trans and N, in apparent contradiction with a theoretically suggested lower bound.
