“Strange particle” breaks down the Charge Symmetry in atomic nuclei
The nuclear force which binds up protons and neutrons in a nucleus originates from the strong interaction between quarks. Though Dr. Yukawa’s meson exchange theory successfully explained important characters of the nuclear force, it is not enough to understand all nature of the nuclear force. Complete understanding of the nuclear force is one of the key issues in nuclear physics. -

KamLAND-Zen
Neutrinos are the elementary particles, but they have no electric charges and can be antiparticles themselves. The Research Center for Neutrino Science has conducted an experiment, KamLAND-Zen, to verify the Majorana nature of the neutrinos by finding the “Neutrinoless double beta decay”, which is considered to be the only detectable phenomenon, if neutrinos are the Majorana particles. -

Antiferromagnetic Skyrmions
Cooperation and competition between quantum effect and non-linear effect in strongly interacting electron systems provide a number of exotic superconductivity, magnetism, dielectrics and others, which have attracted much attention from fundamental and application points of view. -

Hidden states in correlated electron system revealed by light and computer simulation
Cooperation and competition between quantum effect and non-linear effect in strongly interacting electron systems provide a number of exotic superconductivity, magnetism, dielectrics and others, which have attracted much attention from fundamental and application points of view. -

Hypernuclei as relativistic baryon many-body systems
In recent years, the so called “beyond-mean-field approach” has been rapidly developing owing to the development of computer powers. In this approach, the symmetries broken in the mean-field approximation are restored by the projection technique, and in addition, a quantum fluctuation of the mean-field is also taken into account. We have applied this approach to hypernuclei, and for the first time we have succeeded in describing spectra of hypernuclei based on a relativistic baryonic many-body approach. -
