I have been mostly working on theoretical nuclear physics, in particular microscopic theories of nuclear structure, effective interactions between nucleons in nuclei and nuclear many-body problems.
A nucleus can be viewed as a close packing system of nucleons bound together under the influence of strong interactions of nuclear forces. In studying dynamical aspects of many-body systems, one may first introduce fundamental modes of motion such as independent particle motions in an average potential, collective vibrations about the equilibrium and collective rotations of the system if the equilibrium configuration is anisotropic. In a nuclear system, however, the coupling between them is quite strong and it can even affect the fundamental modes themselves. Therefore, the construction of fundamental modes and the study of the coupling between them have been the important subjects for the theory of nuclear structure.
My research interests include quantum many-body problems, symmetries and symmetry violations at the subatomic level, the nature of nuclear interactions, origin of the superconductivity and the pairing correlations in nuclei, exotic nuclear shapes and deformations, structure of nuclei with large neutron or proton excess, anharmonicities in nuclear collective motions, formulations and applications of boson expansion theories.
