Abstract

The Symplectic Shell Model (SpSM) is a group theoretically inspired alternative to the so-called no-core shell-model (NCSM). As these models span the same (complete) shell model space, they yield identical results. However, the SpSM can be shown to yield results that are typically within ~1% of the corresponding NCSM results in model spaces that can often be several orders of magnitude less than that of the full space. This in turn enables studies of heavier and more complex systems that cannot currently be reached using the NCSM. Details regarding the "group theoretical magic" that enables this result will be shared, including a clear articulation of linkages with earlier models, starting with the simplest Bohr-Mottelson picture of nuclear structure. Some additional prospective benefits of the SpSM framework will be proffered.
