A (Dummy's) Guide to Working with Gapped Boundaries via (Fermion) Condensation
Jiaqi Lou, Ce Shen, Chaoyi Chen +1
We study gapped boundaries characterized by "fermionic condensates" in 2+1 d topological order. Mathematically, each of these condensates can be described by a super commutative Fr…

Entanglement Entropy of Topological Orders with Boundaries
Chaoyi Chen, Ling-Yan Hung, Yingcheng Li +1
In this paper we explore how non trivial boundary conditions could influence the entanglement entropy in a topological order in 2+1 dimensions. Specifically we consider the special…
