- Title: The associahedron as a holographic entanglement polytope
- Abstract summary: We observe an analogy between the structures found in connection with the Arkani-Hamed-Bai-He-Yan (ABHY) associahedron used for understanding scattering amplitudes, and the one used for understanding space-time emerging from patterns of entanglement.
Our observations hint at the possibility that the factorization properties of scattering amplitudes are connected to the notion of separability of space-time as used in the theory of holographic quantum entanglement.

- Abstract: By employing the ${\rm AdS}_3/{\rm CFT}_2$ correspondence in this note we
observe an analogy between the structures found in connection with the
Arkani-Hamed-Bai-He-Yan (ABHY) associahedron used for understanding scattering
amplitudes, and the one used for understanding space-time emerging from
patterns of entanglement. The analogy suggests the natural interpretation for
the associahedron as a holographic entanglement polytope associated to the
${\rm CFT}_2$ vacuum. Our observations hint at the possibility that the
factorization properties of scattering amplitudes are connected to the notion
of separability of space-time as used in the theory of holographic quantum
entanglement.
