Capturing Many-Body Correlations within the Nuclear Ab initio Framework

Abstract: Ab initio nuclear many-body methods have become powerful tools for describing nuclei across the nuclear chart, providing predictive insights into nuclear structure and dynamics from realistic QCD-based interactions. This talk reviews the basic principles of these approaches, highlights recent advances in their extension to deformed nuclei, including the newly developed deformed self-consistent Green’s function method, and discusses strategies to mitigate their demanding computational cost, with a particular emphasis on emulators.
