| Research Abstract |
We construct the numerical method in which molecular dynamics simulation is combined with numerical iteration method for searching periodic solutions and with linear stability analysis of the periodic solutions in order to investigate the structure and stability of intrinsic localized modes excited in crystals. We investigate the structure and stability of intrinsic localized modes systematically. The results indicate that the possibility of the change of the structure of crystals due to nonlinear energy localizations.
