AharonovBohm effect on entanglement entropy in conformal field theory
Abstract
We consider the AharonovBohm 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 AharonovBohm phase factor which is proportional to the Wilson loop is represented as insertion of twist operators. We compute exactly the Rényi entropy from a four point function of twist operators in a free charged scalar field.
