Current Status of TOPTIER Theory

TOPTIER(TOP-Tier Platform in Extreme Rare Isotope Science) theory primarily aims to conduct internationally competitive and leading theoretical research in nuclear physics by developing both ab initio approaches and phenomenological methods. Given the nature of nuclear theory related to rare isotopes, it is evident that producing worldclass 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.
