Abstract

We study the dynamics of an heteropolymeric chain relaxing toward a new equilibrium configuration after the action of an external perturbation. We compare the results from Monte Carlo simulations with the results of a Langevin normal mode decomposition. We discuss, for sake of comparison, the case of an ordered homo-polymeric chain. We discuss the dependence of the relaxation stretching exponent over the system size by studying chains constituted by 15 and 30 points.
