Formation of Simple Patterns in Complex Atomic Nuclei from First Principles
- Kristina Launey, Louisiana State University
Wednesday, March 26, 4:10 PM - Nuclear Science Seminar
NSCL Lecture Hall
In this talk, I will discuss two of the key questions in nuclear physics, namely, understanding atomic nuclei with their diverse properties from first principles (tied to the underlying physics foundation) and the origin of simple patterns emerging in the complex nuclear system. In particular, I will talk about the multi-facet challenges -- and the way our innovative symmetry-guided framework has addressed key limitations -- of a large-scale first-principle modeling of atomic nuclei, from well-known stable to experimentally inaccessible rare isotopes, crucial for advancing our knowledge about the element formation and stellar evolution. Within this framework, our recent findings unveil a feature common to the low-energy structure of nuclei that has heretofore gone unrecognized in other first-principle studies; namely, the emergence, without a priori constraints, of simple orderly patterns that favor strongly deformed configurations and low spin values -- a feature that points to a novel approximate symmetry that underpins nuclear dynamics and is central to expanding the reach of first-principle studies to heavier nuclei.
