Dynamics of cluster ionization and neutral atom acceleration

Nanoclusters are simpler systems that engulf most of the complexity of the intense laser matter interactions. While the intra-cluster density is solid-like, the bulk density is orders of magnitude smaller. Inter-cluster plasma dynamics offer a rich variety of parameters to tweak the plasma for unusual effects like neutral atom and negative ion acceleration. Rydberg excited states generated in these systems have a decisive effects on the ion charge states and their angular distributions. In this talk I present a review of the dynamics of the intra-cluster and inter-cluster effects in nano-plasmas.
