Construction and classification of symmetry protected topological phase in interacting fermion systems - Zheng-Cheng Gu

The classification and lattice model construction of symmetry protected topological (SPT) phases in interacting fermion systems are very interesting but challenging. In this talk, I will address this problem based on the fluctuation domain wall picture. If time permits, I will also discuss classification of space group SPT phases in interacting fermion systems.
