YITP Event: Special seminar: Zhengcheng Gu (Chinese University of Hong Kong)---"Classification and construction of crystalline topological superconductors and insulators in interacting fermion systems"
Time: 2:30 PM - 3:30 PM
Location: YITP Common Room (Math 6-125)
Abstract: The construction and classification of crystalline symmetry protected topological (SPT) phases in interacting bosonic and fermionic systems have been intensively studied in the past few years. Crystalline SPT phases are not only of conceptual importance, but also provide us great opportunities towards experimental realization since space group symmetries naturally exist for any realistic material. In this talk,I will discuss how to construct and classify crystalline topological superconductors (TSC) and topological insulators (TI) in interacting fermion systems. I will also discuss the relationship between internal symmetry protected SPT phases and crystalline symmetry protected SPT Phases.
