Fundamental symmetry
The many-body effect and amplification effect of fundamental symmetry breaking may be related to the origin of life, e.g., the way in which the spiral structure of DNA only twists clockwise and the fact that the amino acids necessary for life to exist are only of the L type. By focusing on the effects of amplifying symmetry breaking in the atomic nucleus medium of heavy elements, we aim to elucidate the breaking mechamisms in nature in the journey from elementary particles to atoms, and finally to complex particles.

Nuclear matter
Nuclear matter with enormous numbers of nucleons gathered is thought to be realized in neutron stars. Equation of state and components of nuclear matter still remain an attractive subject. We are developing cutting-edge detector system called active target which enables us to measure many reactions at the same time. We are approaching the mystery of strong interaction through the experimental study of breathing mode and nucleon correlation in short-lived nuclei relating to the nature and structure of nuclear matter using active target system.

NUSPEQ group
Our research is aiming at manifesting the nature of the interaction between nucleons through systematic measurements of their nuclear masses and excitation modes. In radioactive nuclei, plenty of mysterious phenomena have been observed such as the mechanism of the creation of and extinction of nuclear magic numbers and the neutron halo effect. We perform experiments of radioactive nuclei by using the newly-constructed OEDO-SHARAQ beamline, operated by CNS and RIKEN, to build a novel picture of atomic nuclei that properly expresses those exotic nature.

Nuclear theory
A nucleus is a quantum many-body system consistiyng of protons and neutrons. We, nuclear thery group, study the nuclear structure theoretically utilizing large-scale shell-model calculations aiming at the elucidation of the exotic structure of neutron-rich nuclei and its interdisciplinary applications. In parallel, we investigate numerical approaches to quantum many-body systems and develop the software to utilize high-performance computing efficiently.
