A Bosonic Model of Quantum Holography
Brian Swingle, Michael Winer
We analyze a model of qubits which we argue has an emergent quantum gravitational description similar to the fermionic Sachdev-Ye-Kitaev (SYK) model. The model we consider is known…
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…
Holographic measurement in CFT thermofield doubles
Stefano Antonini, Brianna Grado-White, Shao-Kai Jian +1
We extend the results of arXiv:2209.12903 by studying local projective measurements performed on subregions of two copies of a CFT in the thermofield double state and investi…
Accelerating cosmology from gravitational effective field theory
Stefano Antonini, Petar Simidzija, Brian Swingle +2
A large class of cosmologies have big-bang / big crunch spacetimes with time-symmetric backgrounds and asymptotically AdS Euclidean continuations suggesting a possible holog…
Enhanced Negative Energy with a Massless Dirac Field
Brian Swingle, Mark Van Raamsdonk
Motivated by traversable wormhole constructions that require large amounts of negative energy, we explore constraints on the amount of negative energy that can be carried by a free…
TF1 Snowmass Report: Quantum gravity, string theory, and black holes
Daniel Harlow, Shamit Kachru, Juan Maldacena +35
We give an overview of the field of quantum gravity, string theory and black holes summarizing various white papers in this subject that were submitted as part of the Snowmass proc…
Holographic measurement and quantum teleportation in the SYK thermofield double
Stefano Antonini, Brianna Grado-White, Shao-Kai Jian +1
According to holography, entanglement is the building block of spacetime; therefore, drastic changes of entanglement will lead to interesting transitions in the dual spacetime. In…
Holographic measurement and bulk teleportation
Stefano Antonini, Gregory Bentsen, ChunJun Cao +3
Holography has taught us that spacetime is emergent and its properties depend on the entanglement structure of the dual theory. In this paper, we describe how changes in the entang…
Can one hear the shape of a wormhole?
Stefano Antonini, Petar Simidzija, Brian Swingle +1
A large class of flat big bang - big crunch cosmologies with negative cosmological constant are related by analytic continuation to asymptotically AdS traversable wormholes with pl…
Accelerating cosmology from a holographic wormhole
Stefano Antonini, Petar Simidzija, Brian Swingle +1
We consider cosmological models in which the cosmology is related via analytic continuation to a Euclidean asymptotically AdS planar wormhole geometry defined holographically via a…
Snowmass white paper: Quantum information in quantum field theory and quantum gravity
Thomas Faulkner, Thomas Hartman, Matthew Headrick +2
We present a summary of recent progress and remaining challenges in applying the methods and ideas of quantum information theory to the study of quantum field theory and quantum gr…
Cosmology from the vacuum
Stefano Antonini, Petar Simidzija, Brian Swingle +1
We argue that standard tools of holography can be used to describe fully non-perturbative microscopic models of cosmology in which a period of accelerated expansion may result from…
Snowmass White Paper: New ideas for many-body quantum systems from string theory and black holes
Mike Blake, Yingfei Gu, Sean A. Hartnoll +5
During the last two decades many new insights into the dynamics of strongly coupled quantum many-body systems have been obtained using gauge/gravity duality, with black holes often…
Holographic boundary states and dimensionally-reduced braneworld spacetimes
Stefano Antonini, Brian Swingle
Recently it was proposed that microscopic models of braneworld cosmology could be realized in the context of AdS/CFT using black hole microstates containing an end-of-the-world bra…
Complexity growth of operators in the SYK model and in JT gravity
Shao-Kai Jian, Brian Swingle, Zhuo-Yu Xian
The concepts of operator size and computational complexity play important roles in the study of quantum chaos and holographic duality because they help characterize the structure o…
Building Bulk Geometry from the Tensor Radon Transform
ChunJun Cao, Xiao-Liang Qi, Brian Swingle +1
Using the tensor Radon transform and related numerical methods, we study how bulk geometries can be explicitly reconstructed from boundary entanglement entropies in the specific ca…
Universal Constraints on Energy Flow and SYK Thermalization
Ahmed Almheiri, Alexey Milekhin, Brian Swingle
We study the dynamics of a quantum system in thermal equilibrium that is suddenly coupled to a bath at a different temperature, a situation inspired by a particular black hole evap…
Cosmology at the end of the world
Stefano Antonini, Brian Swingle
In the last two decades the Anti-de Sitter/Conformal Field Theory correspondence (AdS/CFT) has emerged as focal point of many research interests. In particular, it functions as a s…
Black Hole Microstate Cosmology
Sean Cooper, Moshe Rozali, Brian Swingle +3
In this note, we explore the possibility that certain high-energy holographic CFT states correspond to black hole microstates with a geometrical behind-the-horizon region, modelled…
Subsystem Complexity and Holography
Cesar A. Agón, Matthew Headrick, Brian Swingle
We study circuit complexity for spatial regions in holographic field theories. We study analogues based on the entanglement wedge of the bulk quantities appearing in the "complexit…
Holographic Complexity of Einstein-Maxwell-Dilaton Gravity
Brian Swingle, Yixu Wang
We study the holographic complexity of Einstein-Maxwell-Dilaton gravity using the recently proposed "complexity = volume" and "complexity = action" dualities. The model we consider…
Entanglement of purification: from spin chains to holography
Phuc Nguyen, Trithep Devakul, Matthew G. Halbasch +2
Purification is a powerful technique in quantum physics whereby a mixed quantum state is extended to a pure state on a larger system. This process is not unique, and in systems com…
Entanglement Wedge Reconstruction via Universal Recovery Channels
Jordan Cotler, Patrick Hayden, Geoffrey Penington +3
We apply and extend the theory of universal recovery channels from quantum information theory to address the problem of entanglement wedge reconstruction in AdS/CFT. It has recentl…
Linearity of Holographic Entanglement Entropy
Ahmed Almheiri, Xi Dong, Brian Swingle
We consider the question of whether the leading contribution to the entanglement entropy in holographic CFTs is truly given by the expectation value of a linear operator as is sugg…
