Condensed states of a semiflexible copolymer in poor solvent: Figures of eight and discrete size torii

摘要

We examine the condensed states of a simple semiflexible copolymer in whichthere are two monomer types that are immiscible with each other and with thesolvent. Although this is similar to the well known problem of collapse for asemiflexible homopolymer we find that it gives rise to a much richer variety ofcondensed states. We predict the existence of these states using simpleanalytic arguments and also observe them directly using Brownian dynamicssimulations.
