We are studying novel phenomena of molecular solids and gas hydrates under extreme conditions (e.g. ultra high pressure, high temperature, low temperature, etc.) by Raman and Brillouin scattering spectroscopies. The followings are our recent studies.
 Pressure-induced phase transformation and elastic properties of gas hydrates : Methane hydrate attracts much attention as an energy resource replaced with fossil oil because a huge amount of methane hydrate is lying under the seabed near the Japanese islands. By high-pressure Brillouin spectroscopy, we are estimating the elastic properties of methane hydrate, which is useful for the evaluations of the amount of methane hydrate deposits and the safe methane production. We are also investigating the pressure-induced phase transformations of gas hydrates by high-pressure Raman scattering and neutron diffraction measurements.
 Elastic properties of rare gas solids under extreme conditions : Although rare gas molecules (except for He) simply form fcc solids by Van der Waals interaction, their elastic properties are not well known unexpectedly. Therefore, we are studying the detailed elastic properties of the rare gas solids at the low-temperature and high-pressure conditions by using Brillouin scattering spectroscopy.
