Abstract

The project addresses the intriguing open question of low-energy nuclear physics of how few-body dynamics emerges from the many-body structure in weakly-bound atomic nuclei. We focus on the dominant role played by few-body degrees of freedom in weakly bound nuclei, which normally are only a correction to the single-particle contributions to the nuclear properties of stable nuclei. For that, reaction mechanisms and nuclear structure involving weakly bound exotic nuclei will be investigated with theory and experiments, necessary for a deeper understanding of astrophysical processes such as nuclear reactions in the cosmos for stellar nucleosynthesis and the formation of dense stellar matter. Additionally, we will explore other applications of few-body dynamics to hadrons, cold atomic gases, and condensed matter systems. (AU)
