Theoretical aspects of branched semiflexible polymers — •Maxim Dolgushev and Alexander Blumen — Theoretische Polymerphysik, Universität Freiburg, Hermann-Herder-Str. 3, D-79104 Freiburg, Deutschland

In recent years the theory of semiflexible polymers has seen advances in the mathematical-analytical study of branched structures[1]. Nowadays one can model semiflexible treelike polymers, in which the branching points may have arbitrary functionality and stiffness[2,3]. A further step forward concerns the investigation of semiflexible polymers containing loops, i.e. obeying closure conditions. The treatment of such objects is rendered possible through the maximum entropy principle[4], as we have recently shown for rings[5].
