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. The simulations are performed on parallel computers with help of the simulation package ESPResSo, and we continue to develop algorithms for long range interactions.
A second focus of our research are geometry, flow and transport phenomena in porous media and applications of fractional calculus in physics. Our methods are not only computer simulations, but we also apply numerical methods and statistical physics approaches like stochastic processes, density functional methods, and other approaches.
