Symmetry Adapted Model (SAM)

Results from the novel Symmetry Adapted Model (SAM) for carrying out advanced studies of the structure of atomic nuclei is introduced. SAM takes full advantage of symmetries underlying the nuclear dynamics; namely, the Wigner Supermultiplet Symmetry U(4) ⊃ SU(2)_spin x SU(2)_isospin along with a major revision of the associated spatial U(3) ⊃ SO(3) methodology. SAM can accept either ab-initio and/or phenomenological interactions and is able to surpass the limitations of its predecessor SA-NCSM.

The overarching objective is to feature SAM alongside other models on an interactive (Mathematica-like) platform that makes nuclear structure studies accessible to everyone. Specifically, it allows for users to explore novel ideas without a need for them to engage in hard coding and/or code maintenance. It also offers storage solutions, fast data retrieval, and is deployed on the best available supercomputers with functionalities that are ready for plug-in-and-play applications. In addition, it provides practical plotting functionalities such as displaying excitation spectra, binding energies and various transition rates as may needed by its subscribers.
