Second Rényi entropy and annulus partition function for one-dimensional quantum critical systems with boundaries
We consider the entanglement entropy in critical one-dimensional quantum systems with open boundary conditions. We show that the second Rényi entropy of an interval away from the boundary can be computed exactly, provided the same conformal boundary condition is applied on both sides. The result...
