Nuclear Structure Theory
- Anna McCoy (Argonne National Laboratory)
This presentation explores both historical and modern advancements in nuclear structure theory, evolving from the nuclear shell model introduced 75 years ago. It will provide an overview of quantum many-body tools such as the shell model and the configuration interaction (CI) technique, alongside newer methods that incorporate and leverage quantum complexity, entanglement, and the openness of...
Shapes and shape evolution have long been a discussion focus in nuclear physics. The study of this topic requires extension of shell model calculation to heavy mass regions. There, one faces two major problems: how to incorporate a large model space in the calculation and how to interpret the results with the vast shell-model output. A promising tool is the Hartree-Fock-Bogolyubov plus...
Intruder states, involving shell model configurations in which nucleons are excited out of the valence shell, feature prominently in the excitation spectra of nuclei across the nuclear chart. In comparison to “normal” states, for which the structure is well described by valence space configurations, “intruder” states have access to a much larger configuration space, allowing them to develop...
Over the years it was established that collective rotation of the nuclei can act as a tool to access new physical features or increase the stability of specific nucleonic configurations. The most well known case is superdeformed (SD) rotational bands: they cannot be formed at low spin in most of the regions of nuclear chart but collective rotation of the nuclei leads to the formation of SD...
