Zheng-Cheng Gu - Construction and classification of symmetry protected topological phase

This talk was part of the of the Online Workshop on "Topological Orders and Higher Structures" of the Thematic Programme "Higher Structures and Field Theory" held August 3 - 21, 2020 digitally.

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. I will also discuss classification of space group SPT phases in interacting fermion systems.
