# Entanglement in descendants

@inproceedings{Chowdhury2021EntanglementID, title={Entanglement in descendants}, author={Barsha G. Chowdhury and J. R. David}, year={2021} }

We study the single interval entanglement and relative entropies of conformal descendants in 2d CFT. Descendants contain non-trivial entanglement, though the entanglement entropy of the canonical primary in the free boson CFT contains no additional entanglement compared to the vacuum, we show that the entanglement entropy of the state created by its level one descendant is non-trivial and is identical to that of the U(1) current in this theory. We determine the first sub-leading corrections to… Expand
