   The role of topological constraints in soft matter physics

   Prof. Kurt Kremer, Max Planck Institute for Polymer Research, Ackermannweg 10, 55128 Mainz, Germany

Soft Matter covers most biological systems and a huge class of everyday products ranging from simple plastics, high tech polymers for electronics to most foods. Its properties are mostly governed by the statistical mechanics of strongly fluctuating huge molecules, such as polymers. For this the fact that polymer chains cannot cross through each other is of central importance to many aspects of soft matter physics being rheological properties of synthetic polymers or so called chromosome territories in biophysics. However, despite its relevance, the theoretical treatment still poses many unsolved questions. In the present talk, after a general introduction into soft matter physics, the role of topological constraints on conformational as well as dynamical properties for a variety of macromolecular systems will be discussed and compared to experiment and simulation results.
