Introduction of Research

The atomic nucleus is a self-organized many-body quantum system of nucleons - protons and neutrons. The nucleus takes on geometrical shapes that correspond to a spherical vibrator, and ellipsoidal deformed rotor. This feature is known as collective motion, which exhibits remarkable regularities and symmetries as observed in the vibrational or rotational energy spectra and characteristic patterns of electromagnetic transition rates. How the atomic nucleus organizes itself into a variety of shapes and what are the microscopic origins have been a central problem in low-energy nuclear physics, and are also common to quantum many-body systems in general.

My research is mainly focused on the above problem, and I am primarily interested in developing a theory allowing for a universal and microscopic description of the structure and dynamics of heavy nuclei, constructed by using state-of-the-art nuclear many-body methods. It has nowadays become possible to produce and accelerate radioactive nuclei at experiments, which has opened many new avenues for low-energy nuclear physics. I am involved in international collaborations with both theoretical and experimental nuclear physicists concerning the nuclei that are of interest for experiments using RI beams. I also study some basic problems in particle physics and astrophysics in the context of nuclear physics, aiming, in particular, to provide inputs with the related experiments.
