Description
We study a single semiflexible polymer chain immersed in a poor solvent. Such chains are stiff and are known to form toroidal globules. Here we examine the effects of hexagonally ordered packing of the chains. This packing induces a series of sharp transitions in the circuit number (number of complete circuits of the toroid) and major radius of the torus as a function of chain length. Circuit numbers corresponding to closed shells are strongly favoured and circuit numbers corresponding to a...[Show more]
