| Research Abstract |
We have developed nano-optical response theory for describing local-electron dynamics on metal surfaces and a computational method based on the theory in an effort to understand near-field excitation dynamics in nano molecular structures. We further developed a simple embedded-cluster model subject to an outgoing-wave boundary condition at the edge of the cluster and investigated adsorbate-surface systems. This open-boundary cluster model is free from artificial waves reflected at the cluster edge, and thus the computed adsorbate properties are almost independent of the model cluster size.
