All the research projects are based on groups from at least two universities. In this way groups which are working at different places will be bound together. Within the research projects frequent exchanges of students will be encouraged. In addition to the projects several other measures will be taken to bring the different groups and especially the students and PhD students together. There will be block lectures, seminars, summer schools and colloquia. Guest scientist will be jointly invited, so that groups at different locations will benefit from their presence. All these measures will help to increase and strengthen the collaboration between the physicists and engineers at the different locations.
