      Due to the lack of appropriate instrumentation, the amount of accurate and precision data is limited on basic physical properties connected with quantum effects and low-energy excitations in the fields of combined high pressure and low temperature. A technical breakthrough has been achieved with a set-up at ISSP, University of Tokyo, equipped with a cubic-anvil device and a top-loading cryostat. Many interesting phenomena originated from electron-electron correlation effects, such as high-Tc superconductivities, spin fluctuations, charge and valence fluctuations, and others near a quantum critical point, have been revealed at pressures extended far beyond 10 GPa and at temperatures down to ca. 2 K, some topics of which are reviewed.

      Experimental studies on rheology of mantle minerals at pressures higher than 3 GPa and at high temperature have been conducted based on recent experimental techniques in order to address the material transport in the Earth's interior. The high-pressure deformation experiments using deformation-DIA apparatus and rotational Drickamer apparatus have been carried out with in situ stress and strain measurements. The rheological data for olivine, wadsleyite, garnet and periclase at high pressure provide useful information necessary to discuss the rheological structure in the Earth's mantle. Further systematic studies are required to understand the effects of temperature, pressure, stress, chemical composition, water content and microstructure on rheology of deep Earth materials.
