报告摘要:
Recent years have witnessed the vigorous researches on novel physics in synthetic lattice systems, such as in cold atom systems and in metamaterials.We show that metamaterials as synthetic topological materials can realize unprecedented topological phenomena. These including the bulk-disclination correspondence which could serve as a new probe of topological crystalline materials and local flux manipulation which provide a foundation toward fundamentally new materials and phenomena . We demonstrate all these effects with complimentary theory and experiments, and pointing out its relation with physics in graphene and other solid state materials.
