# Aharonov-Bohm effect on entanglement entropy in conformal field theory

@article{Shiba2017AharonovBohmEO, title={Aharonov-Bohm effect on entanglement entropy in conformal field theory}, author={Noburo Shiba}, journal={Physical Review D}, year={2017}, volume={96}, pages={065016} }

We consider the Aharonov-Bohm effect on entanglement entropy for one interval in (1+1) dimensional conformal field theory on a one dimensional ring. The magnetic field is confined inside the ring, i.e. there is a Wilson loop on the ring. The Aharonov-Bohm phase factor which is proportional to the Wilson loop is represented as insertion of twist operators. We compute exactly the Renyi entropy from a four point function of twist operators in a free charged scalar field.
