摘要: We present a statistical mechanics analysis of the finite-size elasticity model polymers, consisting domains that can exhibit transitions between more than one stable state at large applied force. The constant-force (Gibbs) and constant-displacement (Helmholtz) formulations single-molecule stretching experiments are shown to converge in thermodynamic limit. Monte Carlo simulations continuous three-dimensional polymers variable length carried out, based on this formulation. demonstrate experimental force-extension curves for short long described by unique universal model, despite differences chemistry rate-dependence transition forces.
