摘要： 

Modern nuclear physics aims to understand nuclear structure and decay properties from fundamental nucleon interactions. Phenomenological models successfully describe known data but lose predictive power for exotic nuclei and rare processes. Recent advances in ab initio methods employ nuclear forces from chiral effective field theory and solve the many-body problem with systematically improvable techniques.

This lecture presents progress in extending ab initio many-body methods to medium-mass and heavy open-shell nuclei, introducing the in-medium similarity renormalization group (IMSRG) and in-medium generator coordinate method (IM-GCM). These tools now enable microscopic studies of complex phenomena previously inaccessible to first-principles calculations.

Applications cover the microscopic origin of nuclear magic numbers, deformation emergence in the island of inversion, and nuclear matrix element calculations for neutrinoless double-beta decay. Observation of this rare process would confirm the Majorana nature of neutrinos and indicate physics beyond the Standard Model; reliable matrix elements are essential for interpreting current and future experiments.

The lecture concludes with an outlook on future ab initio nuclear theory developments and their impact on nuclear structure, fundamental symmetries, and new-physics searches.
