Physics Group Meeting

In the first part of the talk, I’ll explore whether EE’s of subalgebras not organized by position space in a holographic CFT may be useful for bulk reconstruction. In particular I'll explain how the lengths of non-minimal geodesics in AdS3 conical defect backgrounds can be interpreted as the EE's of certain subalgebras in the dual CFT. This part will be based on 1608.02040. In the second part of the talk, I'll discuss how the Ryu-Takayanagi area seems to be a boundary entropy, that is the analog of an edge term one finds when defining EE in a gauge theory, and how one might try to test this.
