Nuclear electromagnetic moments provide essential information in our understanding of nuclear structure. Observables such as electric quadrupole moments are highly sensitive to collective nuclear phenomena. In contrast, magnetic dipole moments offer sensitive probes to test our description of microscopic properties such as those of valence nucleons. Although great progress was achieved in...

Clustering is an intriguing phenomenon in nuclear structure. Correlations between nucleons result in the formation of subunits (cluster) inside the nucleus. The most typical cluster is the alpha particle, which is present not only in light nuclei, but also observed in heavy nuclei as the alpha decay phenomena.
Recently, we have proposed a quantity "local alpha strength function" ...

The energy density functional (EDF) approach in nuclear physics often utilizes mean-field wave functions that intentionally break certain symmetries of the Hamiltonian to incorporate static correlations.

To achieve a precise description of nuclear properties and recover quantum numbers, the restoration of these broken symmetries is essential. While symmetry-restored calculations are common... -

The isospin symmetry breaking part of the nuclear interaction is a small part of the whole; however, it sometimes gives important contributions to nuclear properties, such as the difference of mirror nuclei, the isobaric analog states, and the neutron-skin thickness. The isospin symmetry breaking terms also affect the estimation of the slope parameter of the nuclear symmetry energy.

Observations of spectroscopic properties in some nuclei suggest the existence of shape fluctuations and shape coexistence phenomena. To describe such phenomena, it is obvious that a mean-field approach, which treats small-amplitude dynamics around a single-reference state, is not enough, and a beyond-mean-field approach is necessary. The five-dimensional quadrupole collective Hamiltonian...
