We study the dynamics of atoms, molecules, and spins in various materials using neutron scattering techniques, to discover novel phenomena and universality inherent in a wide range of materials. Neutron is a powerful probe to detect hydrogen atoms. Observation of hydrogen quantum dynamics and proton/hydride ion conduction is one of our major research interests. Hydrogen is known as a quantum atom, but the quantum nature of hydrogen is rarely manifested. We will try new measurement techniques, such as coherent/incoherent separation of light hydrogen using polarized neutrons, and find dynamics that have not been captured so far. Hydrates, functional liquids, spin glass, and single-molecule magnets (which behave like nanomagnets) are also within our scope. These studies require measurements over a wide dynamic range, and we are using a variety of neutron spectrometers in domestic and foreign facilities, as well as developing a neutron scattering spectrometer.
