• DIVISION OF QUANTUM UNIVERSE

  This division aims to create new fields of fundamental physics that combine atomic physics, quantum optics, mathematical science, and quantum beam physics with cosmology and particle physics. A more specific purpose is to open up the new field of “neutrino mass spectroscopy with atoms” using a “macro-coherent amplification mechanism”, which is a new principle invented and proven experimentally in this division, and also a production technology for quantum coherent targets. The challenge will be to clarify various neutrino-related issues, such as the nature of neutrino mass (Dirac or Majorana), mass hierarchy, absolute neutrino mass, and the CP violating phase, all of which give essential clues to the origin of the matter-antimatter imbalance in our universe. The division creates new research fields, innovative quantum optics using the nucleus, and a coherent quantum beam based on a novel principle, aiming at future development of both fundamental and applied science.

• DIVISION OF PHOTOSYNTHESIS AND STRUCTURAL BIOLOGY

  The research areas of this division include three disciplines, structural biology, functional analysis, and artificial photosynthesis, all focusing on the structure and function of proteins involved in oxygenic photosynthesis and the creation of artificial photosynthesis systems based on naturally evolved photosynthetic reactions. The structural biology group aims to resolve the molecular structure of the two photosystems at the atomic level by using high-energy X-rays at Spring8 and the X-ray free-electron laser (XFEL) at SACLA to gain a deeper understanding of high-efficiency light utilization and the light-induced water-splitting reaction mechanism. The functional analysis group studies the function of proteins involved in photosynthetic electron transport using molecular biological, biochemical, and biophysical approaches to generate photosynthetic organisms that are able to grow in high stress environments. This group also tries to produce devices that generate electrical power or hydrogen, using photosynthetic proteins. The artificial photosynthesis research group aims to create an artificial photosynthesis system by mimicking the structure of the oxygen-evolving complex of photosynthetic organisms. This group is interested in developing new transition metal complexes that efficiently split water into protons and oxygen using light energy.

• DIVISION OF SUPERCONDUCTING AND FUNCTIONAL MATERIALS

  This division focuses on the understanding and development of superconducting, functional, and energy storage materials. Particular strengths are in the experimental techniques of chemical synthesis and spectroscopy and the theories of superconducting materials, clathrate hydrates, and aqueous solutions. In the superconductivity section, we search for new superconductors with higher transition temperatures as well as novel superconducting states such as chiral superconductivity, using chemical synthesis, advanced photoemission spectroscopy, and superconductivity theory. The compounds we are studying include (1) borides and carbides, (2) transition-metal oxides, pnictides, and chalcogenides, (3) Ce and Pr based intermetallic compounds. We synthesize new materials using various advanced techniques, such as high-pressure synthesis; observe electronic structure with our advanced photoemission spectroscopy; and predict the existence and properties of new materials as well as novel superconducting states, using first-principles calculations. The section specializing in new functional materials designs efficient synthetic methods based on organometallic chemistry. These methods provide functional organic materials, such as fused π-electron molecules, to be used as organic superconductors, in field-effect transistors, and as organic photovoltaics. The energy storage materials section works to understand the physical properties of clathrate hydrates and a variety of liquids, including aqueous solutions, using molecular simulation and statistical mechanics. Current work includes theoretical studies on the stability, formation, and melting of hydrates, and also on the structures and phase transitions of liquid - liquid interfaces.
