A de Sitter Anti-Scrambling Algebra
Wentao Cui, David K. Kolchmeyer
We study the algebra of observables of a semiclassical observer in de Sitter space. When operators are time-evolved by a scrambling time, out-of-time-ordered correlation functions…

Chaos and the Emergence of the Cosmological Horizon
David K. Kolchmeyer, Hong Liu
We construct algebras of diff-invariant observables in a global de Sitter universe with two observers and a free scalar QFT in two dimensions. We work in the strict $G_N \rightarro…

Long-range wormhole teleportation
Joseph D. Lykken, Daniel Jafferis, Alexander Zlokapa +4
We extend the protocol of Gao and Jafferis arXiv:1911.07416 to allow wormhole teleportation between two entangled copies of the Sachdev-Ye-Kitaev (SYK) model communicating only thr…
