*Welcome to [#z2209544] *About us [#t189815f] The purpose of our research is to describe physical phenomena from the microscopic subatomic scale to macroscopic cosmic scale in a unified manner. The current problem is to understand how quarks are confined in hadrons such as mesons and nucleons, and how simple fundamental laws lead to the variety of phenomena we see. We believe that the answer lies in understanding (1) how hadrons are formed from quarks and gluons, and (2) how atomic nuclei are formed from the hadrons. They are both difficult problems of the strong interaction. For (1), we use effective models inspired by super-conductivity and string theory, and methods of supercomputer simulations. For (2), we study structure of all nuclei using relativistic mean field method, and by including the force mediated by Yukawa's pion. In particular, Yukawas' force is considered to be the origin of the rich structure of nuclei such as clustering, unstable structure and deformations. In these theoretical researches, we communicate experimental groups of RCNP-Ring cyclotron and of Laser-Electron-Photon at SPring-8.
