| Research Abstract |
We investigate structure and dynamics of nonlinear localized vibration (intrinsic localized mode, ILM) in crystal structure due to the nonlinear interaction potential between atoms. We consider ILM in graphene sheet which is two dimensional structure of carbon atoms. By combining molecular dynamics method and Newton-Raphson method, we search localized vibration in graphene sheet and investigate its structure. We also investigate stability of localized structure. These results imply possibility that ILM can be trigger of change of structure in atomic scale in crystal such as cutting and recombination of carbon-carbon bonds.
