Research

Extending the capabilities of quantum beams by developing advanced analysis methods in close collaboration with experiments-

  • First Principles Molecular Dynamics Simulations of Chemical Reactions
    Advanced simulation techniques for chemical reactions developed based on first principles molecular dynamics are applied to the research of physical and chemical properties of solutions, mechanisms of catalytic reactions, etc.
  • Theoretical Study of Excitation Spectra on Transition Metal Oxides
    The electronic properties and the excitation spectra of the transition metal oxides are clarified by using numerical techniques such as exact diagonalizations on small cluster systems. In particular, the spectral features of the resonant inelastic x-ray scattering on high-Tc cuprates, nickelates, and so on, are proposed theoretically.
  • Theoretical Study on Resonant Inelastic X-ray Scattering in Transition Metal Oxides
    The electronic states of the transition metal oxides such as high-Tc cuprates are clarified by using the exact numerical diagonalization, etc., and the spectral features of the resonant inelastic x-ray scattering, x-ray photoelectron spectra, etc. are theoretically predicted for these materials.
  • Theoretical Study on Resonant Inelastic X-ray Scattering in highly correlated electron systems
    The electronic excitation processes in highly correlated electron systems like high-Tc conductors are clarified on the microscopic level via theoretical analysis of the resonant inelastic x-ray scattering spectra measured at SPring-8, etc., by using the electronic structures calculated precisely.
  • Large-Scale Numerical Simulation Study on Quantum Spin Systems
    The frustrated systems like the kagome-lattice antiferromagnet, the triangular-lattice antiferromagnet and the spin nanotube, which can exhibit the quantum spin liquid related to the high temperature superconductivity, are theoretically investigated by the large-scale numerical exact diagonalization, using the K-computer etc.
