The second summer workshop on “Ultrafast Cluster Dynamics” will take place on August 23-24 at the Max-Born-Institut. Following the first edition organized by Thomas Fennel in Rostock in 2014, this workshop will be organized by Bernd Schütte in collaboration with Daniela Rupp and Maria Krikunova from the TU Berlin. We expect about 45 participants from Germany, but also from abroad. In addition to 9 talks about nonlinear cluster dynamics, we will have 14 interesting poster presentations. Please contact the organizers for more information.
