摘要 |
In this talk, I would like to show you our solution to a long standing open problem---ground state degeneracy of topological phases on open surfaces---in the area of topological phases, via a mechanism, anyon condensation. Along with this, I would briefly tour you through the framework offered by anyon condensation that may unify various aspects of topological orders, such as topological phases, symmetry-protected topological phases, symmetry-enriched topological phases, and so on. Anyon condensation also offers in its framework a systematic solution to other seemingly different problems about topological orders, e.g., the patterns of global-symmetry fractionalization, and the classification of gapped domain walls/boundaries. |
