Few-body structural properties reveal many-body structures

By diffusion Monte Carlo and pure estimators we explore: ground-state properties of quantum few- body systems, consisting of up to 3 different atomic species ; stability and structure of different clusters consisting of spin-polarized H, He, Ne, Ar, alkali and alkaline-earth isotopes ; and model systems to test influence of a potential model. Among structural properties we emphasize helium dimers and trimers which can be compared with the most recent experimental results obtained by Coulomb explosion imaging of diffracted clusters, and helium-alkali pentamers which already indicate behavior noticed in nanodroplets.
