Modular invariance and thermal effective field theory in CFT
Kuroush Allameh, Edgar Shaghoulian
We use thermal effective field theory to derive that the coefficient of the first subleading piece of the thermal free energy, , is equal to the coefficient of the subleading…
Quantum gravity and the measurement problem in quantum mechanics
Edgar Shaghoulian
The measurement problem in quantum mechanics is almost exclusively discussed in situations where gravity is ignored. We discuss some recent developments in our understanding of qua…
Encoding beyond cosmological horizons in de Sitter JT gravity
Adam Levine, Edgar Shaghoulian
Black hole event horizons and cosmological event horizons share many properties, making it natural to ask whether our recent advances in understanding black holes generalize to cos…
Entanglement in De Sitter Space
Edgar Shaghoulian, Leonard Susskind
This paper expands on two recent proposals, \cite{Susskind:2021dfc}\cite{Susskind:2021esx} and \cite{Shaghoulian:2021cef}, for generalizing the Ryu-Takayanagi and Hubeny-Rangamani-…
The central dogma and cosmological horizons
Edgar Shaghoulian
The central dogma of black hole physics -- which says that from the outside a black hole can be described in terms of a quantum system with exp states evolving…
Submerging islands through thermalization
Vijay Balasubramanian, Ben Craps, Mikhail Khramtsov +1
We illustrate scenarios in which Hawking radiation collected in finite regions of a reservoir provides temporary access to the interior of black holes through transient entanglemen…
Global symmetry, Euclidean gravity, and the black hole information problem
Daniel Harlow, Edgar Shaghoulian
In this paper we argue for a close connection between the non-existence of global symmetries in quantum gravity and a unitary resolution of the black hole information problem. In p…
Islands in cosmology
Thomas Hartman, Yikun Jiang, Edgar Shaghoulian
A quantum extremal island suggests that a region of spacetime is encoded in the quantum state of another system, like the encoding of the black hole interior in Hawking radiation.…
The entropy of Hawking radiation
Ahmed Almheiri, Thomas Hartman, Juan Maldacena +2
In this review, we describe recent progress on the black hole information problem that involves a new understanding of how to calculate the entropy of Hawking radiation. We show ho…
A symmetry principle for emergent spacetime
Edgar Shaghoulian
There are many examples where geometry and gravity are concepts that emerge from a theory of quantum mechanics without gravity. This suggests thinking of gravity as an exotic phase…
Islands in Asymptotically Flat 2D Gravity
Thomas Hartman, Edgar Shaghoulian, Andrew Strominger
The large-N limit of asymptotically flat two-dimensional dilaton gravity coupled to N free matter fields provides a useful toy model for semiclassical black holes and the informati…
Hamiltonian deformations in quantum mechanics, , and SYK
David J. Gross, Jorrit Kruthoff, Andrew Rolph +1
Motivated by , we introduce and study a wide class of solvable deformations of quantum-mechanical theories. These deformations map the Hamiltonian to a function of itself.…
Replica Wormholes and the Entropy of Hawking Radiation
Ahmed Almheiri, Thomas Hartman, Juan Maldacena +2
The information paradox can be realized in anti-de Sitter spacetime joined to a Minkowski region. In this setting, we show that the large discrepancy between the von Neumann entrop…
in AdS and Quantum Mechanics
David J. Gross, Jorrit Kruthoff, Andrew Rolph +1
Quantum field theory in zero spatial dimensions has a rich infrared landscape and a universal ultraviolet, inverting the usual Wilsonian paradigm. For holographic theories this imp…
Holography at finite cutoff with a deformation
Thomas Hartman, Jorrit Kruthoff, Edgar Shaghoulian +1
We generalize the deformation of CFT to higher-dimensional large- CFTs, and show that in holographic theories, the resulting effective field theory matches s…
Parity and the modular bootstrap
Tarek Anous, Raghu Mahajan, Edgar Shaghoulian
We consider unitary, modular invariant, two-dimensional CFTs which are invariant under the parity transformation . Combining with modular inversion leads to a continuous…
Sparseness bounds on local operators in holographic
Eric Mefford, Edgar Shaghoulian, Milind Shyani
We use the thermodynamics of anti-de Sitter gravity to derive sparseness bounds on the spectrum of local operators in holographic conformal field theories. The simplest such bound…
Detachable circles and temperature-inversion dualities for CFT
Gary T. Horowitz, Edgar Shaghoulian
We use a Weyl transformation between and to relate a conformal field theory at arbitrary temperature on to…
Emergent gravity from Eguchi-Kawai reduction
Edgar Shaghoulian
Holographic theories with a local gravitational dual have a number of striking features. Here I argue that many of these features are controlled by the Eguchi-Kawai mechanism, whic…
Modular invariance on and circle fibrations
Edgar Shaghoulian
I conjecture a high-temperature/low-temperature duality for conformal field theories defined on circle fibrations like and its lens space family. The duality is an exchange b…
Late-time Structure of the Bunch-Davies FRW Wavefunction
George Konstantinidis, Raghu Mahajan, Edgar Shaghoulian
In this short note we organize a perturbation theory for the Bunch-Davies wavefunction in flat, accelerating cosmologies. The calculational technique avoids the in-in formalism and…
Timelike BKL singularities and chaos in AdS/CFT
Edgar Shaghoulian, Huajia Wang
We study the nature of a family of curvature singularities which are precisely the timelike cousins of the spacelike singularities studied by Belinski, Khalatnikov, and Lifshitz (B…
Black hole microstates in AdS
Edgar Shaghoulian
We extend a recently derived higher-dimensional Cardy formula to include angular momenta, which we use to obtain the Bekensten-Hawking entropy of AdS black branes, compactified rot…
Modular forms and a generalized Cardy formula in higher dimensions
Edgar Shaghoulian
We derive a formula which applies to conformal field theories on a spatial torus and gives the asymptotic density of states solely in terms of the vacuum energy on a parallel plate…
