An SYK wormhole under the microscope
Valérie Bettaque, Martin Sasieta, Brian Swingle +1
We derive a large-N wormhole saddle in the Sachdev-Ye-Kitaev (SYK) model for the variance of the thermal one-point function of a heavy operator across realizations of the microscop…
Twirled Perfect Tensor Networks: Computationally covariant holographic tensor networks
Gurbir Arora, Matthew Headrick, Albion Lawrence +3
We define a novel class of tensor networks motivated by the Python's Lunch Conjecture (PLC) in local tensor network models of the black hole interior. We start from the observation…
Baby Universes from Thermal Pure States in SYK
Martin Sasieta, Brian Swingle, Alejandro Vilar López
We construct a simple two-dimensional holographic model of a closed "baby" universe. The baby universe spacetime originates from the black hole interior in Jackiw-Teitelboim (JT) g…
The Baby Universe is Fine and the CFT Knows It: On Holography for Closed Universes
Stefano Antonini, Pratik Rath, Martin Sasieta +2
Big bang/big crunch closed universes can be realized in AdS/CFT, even though they lack asymptotically AdS boundaries. With enough bulk entanglement, the bulk Hilbert space of a clo…
ER for typical EPR
Javier M. Magan, Martin Sasieta, Brian Swingle
What do the typical entangled states of two black holes look like? Do they contain semiclassical interiors? We approach these questions constructively, providing ensembles of state…
Random Circuits in the Black Hole Interior
Javier M. Magan, Martin Sasieta, Brian Swingle
In this paper, we present a quantitative holographic relation between a microscopic measure of randomness and the geometric length of the wormhole in the black hole interior. To th…
Complexity is not Enough for Randomness
Shiyong Guo, Martin Sasieta, Brian Swingle
We study the dynamical generation of randomness in Brownian systems as a function of the degree of locality of the Hamiltonian. We first express the trace distance to a unitary des…
