    "abstract": "We present an extremely simplified model of multiple-domains polymer\nstretching in an atomic force microscopy experiment. We portray each module as\na binary set of contacts and decompose the system energy into a harmonic term\n(the cantilever) and long-range interactions terms inside each domain. Exact\nequilibrium computations and Monte Carlo simulations qualitatively reproduce\nthe experimental saw-tooth pattern of force-extension profiles, corresponding\n(in our model) to first-order phase transitions. We study the influence of the\ncoupling induced by the cantilever and the pulling speed on the relative\nheights of the force peaks. The results suggest that the increasing height of\nthe critical force for subsequent unfolding events is an out-of-equilibrium\neffect due to a finite pulling speed. The dependence of the average unfolding\nforce on the pulling speed is shown to reproduce the experimental logarithmic\nlaw.",
