Title: Emergent dynamical symmetry in the nuclear many-body system from its ab initio description
Abstract: Ab initio nuclear theory provides a predictive and experimentally val- idated microscopic framework for quantitatively describing the nuclear
many-body system, directly from the interactions of its constituent nu- cleons. With this foundation established, we may now look to ab initio
nuclear theory as means for obtaining a fundamental understanding of
emergent nuclear correlations and collective phenomena. In this semi- nar, we will see how ab initio calculations demonstrate the relevance of
symplectic dynamical symmetry, associated with the symplectic group Sp(3, R) of phase space in three dimensions and its SU(3) subgroup, as
an organizing scheme for collective correlations in light nuclei. In par- ticular, we will explore its ability to provide a near complete qualitative
understanding of the low-lying calculated spectrum of the nucleus 7Be, including rotational collective features.
