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…
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…
Entangled universes
Divij Gupta, Matthew Headrick, Martin Sasieta
We propose a generalization of the RT and HRT holographic entanglement entropy formulas to spacetimes with asymptotically Minkowski as well as asymptotically AdS regions. We postul…
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…
Universal Construction of Black Hole Microstates
Ana Climent, Roberto Emparan, Javier M. Magan +2
We refine and extend a recent construction of sets of black hole microstates with semiclassical interiors that span a Hilbert space of dimension , where is the black hole…
Geometric Surprises in the Python's Lunch Conjecture
Gurbir Arora, Matthew Headrick, Albion Lawrence +2
A bulge surface, on a time reflection-symmetric Cauchy slice of a holographic spacetime, is a non-minimal extremal surface that occurs between two locally minimal surfaces homologo…
A principle of maximum ignorance for semiclassical gravity
Jan de Boer, Diego Liska, Boris Post +1
The principle of maximum ignorance posits that the coarse-grained description of a system is maximally agnostic about its underlying microscopic structure. We briefly review this p…
Cosmology from random entanglement
Stefano Antonini, Martin Sasieta, Brian Swingle
We construct entangled microstates of a pair of holographic CFTs whose dual semiclassical description includes big bang-big crunch AdS cosmologies in spaces without boundaries. The…
Microscopic origin of the entropy of astrophysical black holes
Vijay Balasubramanian, Albion Lawrence, Javier M. Magan +1
We construct an infinite family of microstates for black holes in Minkowski spacetime which have effective semiclassical descriptions in terms of collapsing dust shells in the blac…
Microscopic origin of the entropy of black holes in general relativity
Vijay Balasubramanian, Albion Lawrence, Javier M. Magan +1
We construct an infinite family of microstates with geometric interiors for eternal black holes in general relativity with negative cosmological constant in any dimension. Wormhole…
Wormholes from heavy operator statistics in AdS/CFT
Martin Sasieta
We construct higher dimensional Euclidean AdS wormhole solutions that reproduce the statistical description of the correlation functions of an ensemble of heavy CFT operators. We c…
Holographic Complexity of Quantum Black Holes
Roberto Emparan, Antonia Micol Frassino, Martin Sasieta +1
We analyze different holographic complexity proposals for black holes that include corrections from bulk quantum fields. The specific setup is the quantum BTZ black hole, which enc…
Ergodic Equilibration of Rényi Entropies and Replica Wormholes
Martin Sasieta
We study the behavior of Rényi entropies for pure states from standard assumptions about chaos in the high-energy spectrum of the Hamiltonian of a many-body quantum system. We comp…
A Generalized Momentum/Complexity Correspondence
J. L. F. Barbon, J. Martin-Garcia, M. Sasieta
Holographic complexity, in the guise of the Complexity = Volume prescription, comes equipped with a natural correspondence between its rate of growth and the average infall momentu…
Proof of a Momentum/Complexity Correspondence
J. L. F. Barbon, J. Martin-Garcia, M. Sasieta
We show that the holographic Complexity = Volume proposal satisfies a very general notion of Momentum/Complexity correspondence (PC), based on the Momentum Constraint of General Re…
Momentum/Complexity Duality and the Black Hole Interior
José L. F. Barbón, Javier Martín-García, Martin Sasieta
We establish a version of the Momentum/Complexity (PC) duality between the rate of operator complexity growth and a radial component of bulk momentum for a test system falling into…
Holographic Bulk Reconstruction And Cosmological Singularities
José L. F. Barbón, Martin Sasieta
We study the structure of entanglement wedges in the Kasner-AdS geometry, which provides an example of AdS/CFT engineered cosmological singularity. We investigate the specific limi…
