The research project of the graduate college deals with problems of experimental physics, theoretical physics, biophysics and medicine. The aim of the project is to expand the basic knowledge on nonlinear processes in condensed matter, to determine the structure of protein molecules and to translate the physical approach into the description of biomedical systems, which for example shall lead to a better understanding of the evolution of signals in the human brain. The research projects embrace realms of the physics of condensed matter (A) and an interdisciplinary field (B), which deals with topics combining methods of physics, biophyics and medicine. The following list gives an overview of the topics:
A. Nonlinear dynamics of electrons in condensed matter
A1. Nonlinearity and chaos in mesoscopic systems (Brack, Richter, Strunk, Wegscheider, Weiss)
A2. Non-equilibrium transport and noise in carbon nanotubes (Grifoni,Strunk)
A3. Directed transport and ratchet effects in periodic nanostructures (Grifoni, Richter, Wegscheider, Weiss)
A4. Dephasing, relaxation and dissipation in quantum Hall systems (Fabian, Schueller)
A5. Terahertz-induced photo currents in semiconductor nanostructures (Ganichev, Wegscheider, Weiss)
B. Analysis of biomedical signals by methods of nonlinear dynamics
B1. Dynamics, analysis and modelling of biomedical parameters (Brawanski, Lang)
B2. Nonlinear informationtheoretical methods fort he analysis of biomedical signals (Lang, Brawanski, Kalbitzer)
B3. New Algorithms and programs for structural analysis and dynamics of proteins (Kalbitzer, Lang)
While the nonlinear processes involved in project A are well-known in principle, the situation in B is quite the opposite: the systems are so complex, that they cannot be described by few nonlinear equations. In fact, one tries to characterize a system by time-series and correlation analysis of measurement data, such that one can draw conclusions on the state of the system or its behaviour. Here, the main aim is to search for new applications of nonlinear dynamics in biological molecules and physiology are investigated. Along with the research, we have installed a teaching programme, which conveys knowledge on nonlinear and non-equilibrium effects in interdisciplinary courses and enables graduate students and professors to get to know new developments, to understand their own results in a bigger context and present them to a broader audience in seminars and small workshops. All teaching courses are part of the official syllabus of the faculty and open for all students. The graduate college wants to give the opportunity to students and professors to conduct research on current topics in an interdisciplinary, creative environment and to enforce the search for applications.
