Critical evaluation of the computational methods used in the forced polymer translocation

n forced polymer translocation, the average translocation time τ scales with respect to pore force f and polymer length N as τ∼f−1Nβ. We demonstrate that an artifact in the Metropolis Monte Carlo method resulting in breakage of the force scaling with large f may be responsible for some of the controversies between different computationally obtained results and also between computational and experimental results. Using Langevin dynamics simulations we show that the scaling exponent β⩽1+ν is not universal, but depends on f. Moreover, we show that forced translocation can be described by a relatively simple force balance argument and β to arise solely from the initial polymer configuration.
