Corner contributions to holographic entanglement entropy in AdS4/BCFT3

Understand

We study the holographic entanglement entropy of spatial regions with corners in the AdS4/BCFT3 correspondence by considering three dimensional boundary conformal field theories whose boundary is a timelike plane.

• We compute analytically the corner function corresponding to an infinite wedge having one edge on the boundary.
• A relation between this corner function and the holographic one point function of the stress tensor is observed.
• An analytic expression for the corner function of an infinite wedge having only its tip on the boundary is also provided.
