Generalized Wen-Zee Terms
Bo Han, Huajia Wang, Peng Ye
Motivated by symmetry-protected topological phases (SPTs) with both spatial symmetry (e.g., lattice rotation) and internal symmetry (e.g., spin rotation), we propose a class of exo…

A coupled wire description of surface topological orders
Bo Han, Jeffrey C. Y. Teo
Symmetry-protected and symmetry-enriched topological (SPT/SET) phases in three dimensions are quantum systems that support non-trivial two-dimensional surface states. These surface…
