Max Planck Institute for Dynamics and Self-Organization

Turbulence in clouds, neuronal fireworks in the brain, the physics of individual cells and the flow of water and oil through porous stone – these, and other particularly complex systems, are the focus of the research carried out by scientists at the Max Planck Institute for Dynamics and Self-Organization. Here, “complex” means that many individual systems combine to form a whole, the dynamics of which cannot necessarily be identified through the behaviour of the individual systems. Scientists say that these systems “organise themselves”. This holds true for the interaction of neurons in the brain (for example during learning) as well as for the numerous swirls that combine to form a turbulent cloud. There is reason to hope that a better understanding of the latter will enable a more accurate prediction of the future influence of clouds on global climate.

Fighting Turbulence with Eddies

Physics & Astronomy
Turbulence is omnipresent: it plays an important role during planet formation, mixes fuel and air in the cylinder of an engine, but also increases the energy needed for pumps to push oil through pipelines. Björn Hof and his team at the Max Planck Institute for Dynamics and Self-Organization in Göttingen investigate the finer points of how it originates and search for tricks to prevent the eddies from forming where they interfere.

The Power Grid’s Got Rhythm

MPR 3/2012 Materials & Technology
New forms and sources of energy need new power lines as well. In the future, a larger number of small, distributed wind and solar installations in place of a smaller number of large power plants are projected to supply Germany with energy. At the Max Planck Institute for Dynamics and Self-Organization, the Network Dynamics Group headed by Marc Timme is investigating how the high-voltage grid will respond to this and how it can be optimized.

Coordinated fluid transport by ciliated surfaces

2017 Westendorf, Christian; Gholami, Azam; Faubel, Regina; Guido, Isabella; Wang, Yong; Bae, Albert; Eichele, Gregor; Bodenschatz, Eberhard
Cell Biology Complex Systems Material Sciences Neurosciences Solid State Research Structural Biology
Active and directed fluid transport are crucial for the survival of eukaryotic organisms. This is often carried out by ciliated tissues e. g., the inner wall of the ventriclar system in the mammalian brain. Using a novel method the complexity of the cilia driven fluid flow in the third ventricle of the brain is revealed. Furthermore, ciliated tissues, which are capable of driving such complex flows are interesting for synthetic biology and applications in technology. Therefore, our working group at the MPI for Dynamics and Self-Organization currently attempts to rebuild such ciliated carpets. more

Fluid invasion structures in porous media

2016 Herminghaus, Stephan
Complex Systems Material Sciences
The complex structures which emerge when a fluid invades a porous medium are of great relevance for many problems in the geosciences as well as in technology, engineering, and everyday life. Nevertheless, about fifty years of intense research have not been able to identify the dominant mechanisms at work. We have recently found that the solution is much simpler than anticipated. The mechanism is well hidden, but so elementary that high-school math is sufficient to come up with quantitative predictions. more

Biodiversity and extinction

2015 Stollmeier, Frank
Complex Systems Evolutionary Biology

Today's biodiversity is the result of a long-lasting process of origination and extinction of species. The history of this process can be explored by fossil databases. A new mathematical model for the network of dependencies between species helps to improve our understanding of the mechanisms of this process. For instance, the model can explain in which circumstances the extinction of a single species may initiate a mass extinction, and why the growth of the biodiversity on land and in the sea has been qualitatively different from each other.

Network Dynamics: Growth, Risk, Design and Control - Mathematical Concepts for “intelligent” self-organizing processes in Nature and Technology

2014 Timme, Marc; Nagler, Jan
Cognitive Science Complex Systems Computer Science Mathematics Neurosciences

The dynamics of networks determines our lives. From biochemical reactions in cells and neural circuits in the brain to networks of social contacts and the power grid − all these are networks of units that generate complex emergent functions through multiple nonlinear feedback. Yet we do not understand them. Researchers are now breaking new ground on the way to a future “science on the dynamics of complex networks”, a unique cross-disciplinary enterprise that cannot be captured by individual traditional subjects such as physics or biology, engineering or social sciences alone.

The intrinsic pace of the actin cytoskeleton

The role of noise in spreading processes

2013 Hallatschek, Oskar
Cell Biology Complex Systems Evolutionary Biology Infection Biology
Spreading processes occur in many complex systems. They play an important role, for instance, in the formation of epidemics and the spread of evolutionary novelties. Until recently, most theories of those processes ignored or approximated the role of noise. The example of evolution illustrates, however, that random chance effects should not be neglected. We report a substantial advance in the analysis of these and more complex models. more

Turbulent patterns

2013 Schneider, Tobias M.
Complex Systems Mathematics

The transition to turbulence in a fast moving fluid often starts from a localized turbulent seed that grows until it fills the whole domain. Methods stemming from dynamical systems theory allow first steps towards understanding the observed spreading: Recently constructed special solutions of the underlying equations capture aspects of the characteristic spatiotemporal dynamics. The new solutions are created by known pattern formation mechanisms also believed to underlie the characteristic spots and stripes on leopards and tigers.

During the last years HPC-clusters have become common even beyond the established computing centers. The increasing computing power implies higher technical demands on the infrastructure. In particular the efficient cooling of these systems poses a challenge. more
At low speeds fluid flows are laminar and they turn turbulent as the flowrate is increased. The point at which turbulence first occurs cannot easily be predicted even for flows in very simple geometries. Ever since an investigation by Osborne Reynolds in the 19th century scientists tried to determine this point for the fundamentally most important case: pipe flow. Despite many attempts this problem remained unresolved for over 125 years. Scientists from the Max Planck Institute for Dynamics and Selforganization and colleagues from the University of Warwick could finally answer this question. more

Autonomous emulsions

2011 Herminghaus, Stephan
Material Sciences
A concept is put forward which should allow for the realization of functional nano-systems by means of self-assembly of soft matter. The choice of soft matter suggests itself from the fact that nature chose that class of materials for the development of life. It is demonstrated that gel-emulsions with a well-defined droplet size, which self-assemble in defined geometric environments in a predictable way, are in fact suitable for the implementation of complex function. more

The brain on the edge of chaos

2010 Levina, Anna; Herrmann, Michael J.; Geisel, Theo
Complex Systems Neurosciences
The general principles that underlie the function and structure of the brain are not yet fully understood. Recent experimental findings put forward one of the theoretical hypothesis, namely that cortical networks are organized such that they keep themselves near the so called critical point. In many different contests it was shown, that the critical state can be beneficial for brain functions, for example by optimizing sensitivity to the external input. We study analytically and numerically how the neuronal network can reach and maintain criticality. more

Göttingen high-pressure turbulence facility

2009 Bodenschatz, Eberhard
Complex Systems
Advances in key economical and societal issues facing the world, like energy generation, climate change, and pollution, are obstructed by the lack of understanding of turbulence. Turbulence occurs whenever fluid viscous forces are small compared to the dominant driving forces of the flow; in practice this includes most macroscopic natural and technological flows. High turbulence levels under controlled conditions are imperative to allow a systematic investigation. For the first time this is becoming possible at the Göttingen Turbulence facility, which is presented here. more

Collective phenomena far from thermal equilibrium

2008 Herminghaus, Stephan
Complex Systems Material Sciences
If many similar systems are coupled to each other, quite unexpected collective phenomena are sometimes observed. These are important in processes of pattern formation and emergence, as found in the universe as well as ubiquitously on earth. In order to understand these mechanisms, we study simple model systems, such as wet granular matter. A number of interesting similarities is found with well-understood equilibrium systems. This suggests a promising path for in-depth investigation of this lively field of research. more
Increasing human mobility is a key cause of the geographic spread of modern epidemics. Bacteria and viruses can be transported across great distances and transmitted to other people.

Pattern Formation in Biophysics

2006 Luther, Stefan; Beta, Carsten; Bodenschatz, Eberhard
Cell Biology
The mechanisms of spatiotemporal pattern formation in biology and medicine is key to the understanding of living matter from cell to organs. The phenomenon of self-organization is observed in the chemotactic motion of cells forming complex behavior and structures. On an organ level, the nonlinear interaction of cardiac cells is evident in the transition from periodic heart rhythm to spatiotemporal chaos associated with sudden cardiac death. We describe our experimental and numerical approach to gain further understanding of these biophysical systems. more

Hamiltonian ratchets: propulsion by chaos

2004 Dr. Holger Schanz
Complex Systems Material Sciences Quantum Physics
In future mechanical and electronic devices, nanometer scale transport of material, energy and information will rely on novel physical principles. While the role of quantum effects will increase, dissipative processes causing unwanted heating will be reduced as much as possible. We study one particular transport mechanism, the so-called ratchet effect, in the limit of vanishing dissipation. For that purpose an analysis of the complex phase-space structure of Hamiltonian systems is necessary, in which regular and chaotic dynamics typically coexist. more
