Description
Using analytic theory, numerical calculation and Langevin dynamics simulation we demonstrate the existence of a first-order unraveling transition in the stretching of a polymer chain in a poor solvent. The chain suddenly unravels from a "tadpole" or "ball and chain" configuration, to one where the ball shrinks to zero size. In the force curve this appears as a discontinuous drop in the force. This transition occurs under the conditions of most relevance for atomic-force microscope experiments,...[Show more]
