Pore-blockade Times for Field-Driven Polymer Translocation [PDF]

, 2008
We study pore blockade times for a translocating polymer of length $N$, driven by a field $E$ across the pore in three dimensions. The polymer performs Rouse dynamics, i.e., we consider polymer dynamics in the absence of hydrodynamical interactions.
