The second workshop on “Ultrafast Cluster Dynamics” took place from August 23-24 at the Max-Born-Institut, and was organized together with the TU Berlin. Our 40 guests presented 14 exciting posters and 9 talks, which resulted in many lively discussions. A lot of new fascinating results have been obtained since the last workshop that took place 2 years ago in Rostock. We are already looking forward to the next edition of this workshop taking place in Freiburg in 2 years!
