Abstract
We study the passage (translocation) of a self-avoiding polymer through a membrane pore in two dimensions. In particular, we numerically measure the probability distribution of the translocation time , and the distribution of the translocation coordinate at various times . When scaled with the mean translocation time , becomes independent of polymer length, and decays exponentially for large . The probability is well described by a Gaussian at short times, with a variance of that grows subdiffusively as with . For times exceeding , of the polymers that have not yet finished their translocation has a nontrivial stable shape.
