If you have a question about this talk, please contact Kevin Ralley.

In this talk I will review some of the work I have carried out since 2007 on the subject of entanglement entropy. I will focus on some of the main results of our first paper [J.L. Cardy, O.A. Castro-Alvaredo and B. Doyon (2008)] where we studied 1+1 dimensional integrable quantum field theories (QFTs). More precisely, I will review the relationship between the entanglement entropy and correlation functions of twist fields and will then discuss how this connection has been recently tested [E.Levi, O.A. Castro-Alvaredo and B. Doyon (2013)] in the context of integrable quantum spin chains by numerically performing the scaling limit.
