| Research Abstract |
To reveal the origin of Metal-Insulator transition in strongly correlated materials, it is essential to reveal the orbital resolved electronic structures. In this project, we developed the polarization dependent hard X-ray photoemission system, and succeeded to determine the ground state wave function from the linear dichroism of the core level spectra. Furthermore, as for the complementary techniques, we demonstrated the micro soft-X-ray angle-resolved photoemission and the polarized resonant inelastic X-ray scattering for Vanadium Oxides to determine the three dimensional band structure and the orbital polarized electron excitations.
