TO BE DELETED (kept for complation)
To explore the mechanism responsible for the generation of observed matter-antimatter asymmetry in the Universe, the research on fundamental symmetry violations and various fundamental interactions using the laser cooled and trapped heavy elements is being promoted. The understanding of how the symmetry between the matter and antimatter was broken during the evolution of the early universe requires laboratory experiments which search for symmetry violations in the elementary particles such as quarks and leptons; one such phenomenon of our interest is the intrinsic electric dipole moment (EDM) of either elementary or composite systems. In our laboratory, we produce extremely heavy radioactive elements from nuclear fusion reactions. We trap the heavy unstable atoms and cool them using intense laser beams in order to realize the extreme quantum state of matter such as the Bose-Einstein condensate (BEC), which will be used later for the detection of the EDM signal. The construction of a facility containing high density of laser cooled radioactive atoms is in progress, and it serves as a center for carrying out several studies on fundamental symmetries.

CNS Univ. of Tokyo, is an institute to study many-body hadronic system from atomic nucleus to quarks. The development of the accelerator technique, we obtained tools to explore the region that we never reached before.
Among such tools,CNS constructed two big apparatus, SHARAQ and CRIB, at the
RI Beam Factory of RIKEN, which is in a strong research collaboration with CNS.
A new project “OEDO” to obtain degraded exotic RI beams.
In CNS, 8 professors (2 professor, 2 assoc. profs., 1 lecturer and 3 assist. profs.), students and postdocs are extensively working for the latest researches using these big facilities.
