In this talk, I will discuss entanglement entropy of integrable field theories in 1+1 dimensions in the presence
of line defects which preserves integrability. For interacting field theories, integrable defects are topological
while for free theories the defects can be non-topological. Using the replica trick and the form factor
bootstrap method of integrable field theories, I will show that topological defects do not modify the UV
behavior of the bulk entanglement entropy but lead to different corrections in the IR limit. On the contrary,
non-topological defects modify both the UV and IR behavior of the bulk entanglement entropy. |
