TOPTIER theory primarily aims to conduct internationally competitive and leading theoretical research in nuclear physics by employing or developing both ab initio or microscopic approaches and phenomenological methods. Given the nature of nuclear theory related to rare isotopes, it is evident that producing world-class research achievements in theory is, in many cases, difficult without fair collaboration with experiments. While groundbreaking results in nuclear theory itself—independent of experiments—are also important, such achievements will ultimately be validated through collaboration with experimental research, due to the inherent characteristics of the field.
The core idea of this collaboration meeting is to work together in person at the meeting venue.
For each collaboration topic, we anticipate groups of approximately 3–5 (or more) participants working together during the meeting.
