The Workshop on Nuclear Matter in Different Phases and Transitions brought together both theorists and experimentalists working on the properties of nuclear and hadronic matter produced in heavy-ion collisions in various energy ranges. The main focus was on experimental signals revealing the possible phase changes of the matter, taking into account the finite size of the system, and the non-equilibrium features of the observed phenomena. A discussion of phase transitions in other small quantum systems, such as metallic clusters, or atomic Bose-Einstein condensates was also presented. The...
