Research overview:
Studies on problems of magnetic materials of Heisenberg model or Hubbard model and Bose particle system like liquid 4He. We have advanced the study not only with pure theoretical methods but also together with numerical experiments using a computer. Also advancing on the other hand is study in order to solve difficult problems in electron system or helium system by establishing Monte Carlo calculation method for quantum system. We have also studied with respect to nonlinear phenomena like soliton by means of strict method in low-dimensional system.
