We use high-performance computing on supercomputers and parallel clusters to solve complex problems in physics that would otherwise be impossible to solve via analytical methods. Our main research areas are presently to understand the physics of soft matter systems in general, with a particular emphasis on charged systems like polyelectrolytes, charged colloids, ferrofluids and ionic liquids. In addition we are interested in various biophysical problems, flow phenomena, and porous media. Our methods are not only computer simulations, but we also apply statistical physics approaches like density functional methods, fractional calculus, and other approaches. The simulations are performed on parallel computers with help of the simulation package ESPResSo, and we continue to develop algorithms for long range interactions.
- Since Summer 2011, the ICP offers students from German "Gymnasiums" the possiblity to take part in a one-week work experience at our institute , where they can learn about computer simulations.
- "Hydrogels in Poor Solvent - A Molecular Dynamics Study" by Bernward Mann (†2006), Olaf Lenz, Kurt Kremer and Christian Holm is a cover issue of the journal Macromolecular Simulations and Theory.
- Dominic Röhm, member of Axel Arnold's group, is the winner of the NVIDIA Best Program Award, a CUDA competition held at the 20th International Conference on Discrete Simulation of Fluid Dynamics 2011, Fargo, USA . A committee evaluated the submissions and ranked them based on the originality and readability of the code, ease of compiling and running the code, the performance gain compared to a serial CPU version, the quality of the documentation and the scientific content. The lattice Boltzmann GPU code, written during D. Röhm's Diplomarbeit, which is now part of the software ESPResSo, has been awarded with the first place.
- Worldwide largest 3D Microstructure: The team around R. Hilfer provides the worldwide largest discretized porous microstructures on this website. For the first time a correlated and calibrated microstructure of Fontainebleau sandstone of centimeter size was imaged at resolutions covering nearly three decades from submillimeter to submicron (nano-)scales.
