Broadscale examination of the influence of disorder on semiflexible polymers — •Sebastian Schöbl, Klaus Kroy, and Wolfhard Janke — Institut für Theoretische Physik, Universität Leipzig

The structure and behaviour of biological cells is essentially affected by the biomechanical properties of semiflexible polymers. In the form of networks, such as the cytoskeleton, they build up the basic scaffold of eukaryotic cells.

In order to study the mechanical properties of these highly complex systems, both interactions of the polymer with the surrounding network and further perturbing influences have to be taken into account. We investigate the equilibrium structure of semiflexible polymers in different potential landscapes by Monte Carlo simulations. The resulting properties over a wide parameter range with respect to both polymer stiffness and volume fraction of the background potential are presented. The observables taken into account are radius of gyration, end-to-end distribution, tangent-tangent-correlations and curvature distribution.
