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…
Comment on "Comment on "Traversable wormhole dynamics on a quantum processor" "
Daniel Jafferis, Alexander Zlokapa, Joseph D. Lykken +5
We observe that the comment of [1, arXiv:2302.07897] is consistent with [2] on key points: i) the microscopic mechanism of the experimentally observed teleportation is size winding…
JT gravity with matter, generalized ETH, and Random Matrices
Daniel Louis Jafferis, David K. Kolchmeyer, Baur Mukhametzhanov +1
We present evidence for a duality between Jackiw-Teitelboim gravity minimally coupled to a free massive scalar field and a single-trace two-matrix model. One matrix is the Hamilton…
Matrix models for eigenstate thermalization
Daniel Louis Jafferis, David K. Kolchmeyer, Baur Mukhametzhanov +1
We develop a class of matrix models which implement and formalize the `eigenstate thermalization hypothesis' (ETH) and point out that in general these models must contain non-Gauss…
A duality in string theory on AdS
Indranil Halder, Daniel Louis Jafferis, David Kolchmeyer
We consider bosonic string theory on supported by Kalb-Ramond flux. It is well known that the exact worldsheet theory is described by the WZW m…
An effective matrix model for dynamical end of the world branes in Jackiw-Teitelboim gravity
Ping Gao, Daniel Louis Jafferis, David K. Kolchmeyer
We study Jackiw-Teitelboim gravity with dynamical end of the world branes in asymptotically nearly AdS spacetimes. We quantize this theory in Lorentz signature, and compute the…
Entanglement Entropy in Jackiw-Teitelboim Gravity
Daniel Louis Jafferis, David K. Kolchmeyer
We compute the entanglement entropy and Renyi entropies of arbitrary pure states in pure Jackiw-Teitelboim gravity in Lorentz signature. We apply the quantum Hubeny-Rangamani-Ryu-T…
