  • Multiscale modelling of soft materials (Kurt Kremer, MPI for polymer research, Mainz)

After a short general introduction of soft matter and related scientific problems and questions basic methods to simulate polymers, membranes etc. will be introduced and compared to each other. Based on these methods a variety of scale bridging techniques will be discussed and methods to parameterize different coarse grained models will be introduced. Based on the VOTCA Open Source software (http://www.votca.org/) examples will be given. Methodologies covered include (iterative) Boltzmann inversion, Inverse Monte Carlo, Force Matching, and Relative Entropy Minimization. Special emphasis will be given to problems of representability and transferability as well as to the problem of dynamics in coarse grained models. Beyond that recent developments of adaptive resolution simulations (AdResS) will be introduced, which are capable to treat different levels of resolution ranging from path integral quantum calculations to continuum methods within one single simulation.
