| 报告介绍 | 报告摘要： In this talk, we discuss results from some recent theoretical studies on the novel electronic and optical properties of single-molecule junctions, graphene nanostructures, and surface states of topological insulators. Owing to their reduced dimensionality and unique electronic structure, these systems present opportunities for study of unusual manifestation of concepts/phenomena that may not be so prominent or have not been seen in bulk materials. Many-body effects and symmetry often play a critical role in shaping both qualitatively and quantitatively their properties. Several phenomena will be discussed, exploring their physical origin and comparing theoretical results with experiment data. |
