Ground State Degeneracies of Topological Orders on Open Surfaces via Anyon Condensation
Yidun Wan, Fudan University
In this talk, I will solve the problem of the ground state degeneracies of topological orders on open surfaces, using a mechanism called anyon condensation. Along with solving the problem, I will also show that anyon condensation serves as a framework that may unify various aspects of topological orders, such as topological phases, symmetry-protected topological phases, symmetry-enriched topological phases, and so on.
