Translocation of a confined polymer through a hole

Based on an analogy between polymer translocation across a free energy barrier associated with polymer worming through a hole and classical nucleation and growth process, the escape time tau is predicted asymptotically to be N(N/rho)(1/3v) N is the polymer length, rho is the monomer density prior to escape, and v is the radius of gyration exponent. Monte Carlo simulation data collected in the high salt limit (v similar or equal to 3/5) are in agreement with the asymptotic law and provide vivid details of the escape.
