However a single two-level quantum system (UDW detector) that remains outside of the horizon has been shown to distinguish between a black hole and its associated geon counterpart via its different response rates. Here we extend this investigation of the quantum vacuum outside of an $\\mathbb{RP}_2$ geon by considering the entanglement structure of the vacuum stat","authors_text":"Laura J. Henderson, Robert B.
