Our main interests are magnetism in strongly correlated electron systems, in particular, mechanism of coexistence and competition among quantum fluctuations, randomness and high dimensionality in quantum spin systems with randomness (e.g., magnets including impurities) by means of analytic (Green's function theory, spin-wave theory and coherent potential approximation, etc) and numerical (quantum Monte Carlo simulation and exact diagonalization) methods. We have mainly performed large-scale calculation of the quantum Monte Calro simulations by using super-computer systems with parallel processing systems.
