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…

Preparing High-Fidelity Thermofield Double States

Brian J. J. Khor, Nadie LiTenn, Martin Sasieta +1

A major promise of quantum computers is the controlled preparation of many-body quantum states beyond the reach of efficient classical computation. Among the most important targets…

Scaling at Chiral Clock Criticality via Entanglement Renormalization

Shiyong Guo, Brian Swingle

We employ the Multiscale Entanglement Renormalization Ansatz (MERA) tensor network to investigate a critical line of continuous quantum phase transitions of the chir…

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…
