Collective phenomena far from thermal equilibrium

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.
