Symmetric Orbifolds and Entanglement Entropy for Primary Excitations in
Two Dimensional CFT
   [PDF]

Amir Esmaeil Mosaffa
We use the techniques in symmetric orbifolding to calculate the Entanglement Entropy of a single interval in a two dimensional conformal field theory on a circle which is excited to a pure highest weight state. This is achieved by calculating the Reney Entropy which is found in terms of a 2n-point function of primary operators, n being the replica number.
