Abstract:The effect of topology on the collapse transition and instantaneous shape of an energy polydisperse polymer (EPP), a model heteropolymer is studied by means of computer simulations. In particular, three different chain topologies, namely, linear (L), ring (R), and trefoil knot (T), are considered. The heteropolymer is modeled by assigning each monomer an interaction parameter, εi, drawn randomly from a Gaussian distribution. Through chain size scaling, the transition temperature, θ, is located and compared amo… Show more
