Research Subjects
- Dynamics of hydrogen atoms and hydrogen-containing molecules in a wide range of materials
- Excitation characteristics of spin glasses
- Spin dynamics of single-molecule magnets
- Development of neutron scattering instruments and challenges to new measurements
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. Functional liquids, monolayer ice with frustration, spin glass, and single-molecule magnets (which behave like nanomagnets) are also within our scope. Since these studies require measurements in a wide dynamic range, we use neutron spectrometers from around the world and develop neutron scattering spectrometers.
