title: Multiscale dynamics of cluster fragmentation.
abstract: The fragmentation of rare-gas clusters is theoretically investigated over time scales ranging from ionization and electronic excitation ( approximately fs) up to experimentally relevant times ( approximately ms). For this purpose a combination of methods are used, including nonadiabatic molecular dynamics, classical dynamics on the ground electronic state surface, and a kinetic description for the final evaporative cascade. The present multiscale protocol shows that, although the clusters are strongly out of equilibrium upon excitation, the long-time properties appear as statistical already after 1 ps.
