Outline of Final Research Achievements

Original approaches to compute thermoelasticity and thermal conductivity were developed based on the harmonic and anharmonic lattice dynamics theories combined with the internally-consistent DFT+U method, high-pressure and high-temperature elasticities and lattice thermal conductivities of iron and aluminum bearing bridgmanite (Br), ferropericlase (Fp), and post-perovskite (PPv) were calculated. It was found that the pyrolitic composition can reproduce seismological properties observed in the lower mantle and that Fp has thermal conductivity several times larger than the others. The techniques were also applied to iron hydroxide, and then a new high-pressure phase with the pyrite structure was successfully discovered. These results propose new pictures of the mantle dynamics that Earth's mantle is now in the whole convection state, where the upper and lower mantles convect integrally, and the surface water can be transported down to the bottom of the mantle located at 2890 km depth.
