| Outline of Final Research Achievements |
Novotony method was developed by the Grant for the analysis of the two dimensional quantum spin system with the simulation. The parallel computing and the software were developed as well. As a result, despite of the two-dimension lattice, sufficient system size became available and the finite size scaling analysis was also carried out succesfully. Consequently, the detail of the spectral properties around the criticality became transparent. Actually, the magnon bound state in the ordered phase turned out to be a universal physical phenomena.
