Query: Ishibashi States, Topological Orders with Boundaries and Topological
  Entanglement Entropy II -- Cutting through the boundary   We compute the entanglement entropy in a 2+1 dimensional topological order in
the presence of gapped boundaries. Specifically, we consider entanglement cuts
that cut through the boundaries. We argue that based on general considerations
of the bulk-boundary correspondence, the "twisted characters" feature in the
Renyi entropy, and the topological entanglement entropy is controlled by a
"half-linking number" in direct analogy to the role played by the S-modular
matrix in the absence of boundaries. We also construct a class of boundary
states based on the half-linking numbers that provides a "closed-string"
picture complementing an "open-string" computation of the entanglement entropy.
These boundary states do not correspond to diagonal RCFT's in general. These
are illustrated in specific Abelian Chern-Simons theories with appropriate
boundary conditions.
