Gravitational path integral from the deformation

Alexandre Belin, Aitor Lewkowycz, Gabor Sarosi

We study a deformation of large conformal field theories, a higher dimensional generalization of the deformation. The deformed partition function satisfies a fl…

and EE, with implications for (A)dS subregion encodings

Aitor Lewkowycz, Junyu Liu, Eva Silverstein +1

We initiate a study of subregion dualities, entropy, and redundant encoding of bulk points in holographic theories deformed by and its generalizations. This includes bot…

Complexity and the bulk volume, a new York time story

Alexandre Belin, Aitor Lewkowycz, Gabor Sarosi

We study the boundary description of the volume of maximal Cauchy slices using the recently derived equivalence between bulk and boundary symplectic forms. The volume of constant m…

Emergent classical spacetime from microstates of an incipient black hole

Vijay Balasubramanian, David Berenstein, Aitor Lewkowycz +3

Black holes have an enormous underlying space of microstates, but universal macroscopic physics characterized by mass, charge and angular momentum as well as a causally disconnecte…

The boundary dual of the bulk symplectic form

Alexandre Belin, Aitor Lewkowycz, Gábor Sárosi

In this paper, we study the overlaps of wavefunctionals prepared by turning on sources in the Euclidean path integral. For nearby states, these overlaps give rise to a Kahler struc…

Modular Flow as a Disentangler

Yiming Chen, Xi Dong, Aitor Lewkowycz +1

In holographic duality, the entanglement entropy of a boundary region is proposed to be dual to the area of an extremal codimension-2 surface that is homologous to the boundary reg…

Thermalization, Viscosity and the Averaged Null Energy Condition

Luca V. Delacrétaz, Thomas Hartman, Sean A. Hartnoll +1

We explore the implications of the averaged null energy condition for thermal states of relativistic quantum field theories. A key property of such thermal states is the thermaliza…

The Holographic Shape of Entanglement and Einstein's Equations

Aitor Lewkowycz, Onkar Parrikar

We study shape-deformations of the entanglement entropy and the modular Hamiltonian for an arbitrary subregion and state (with a smooth dual geometry) in a holographic conformal fi…

Inside Out: Meet The Operators Inside The Horizon

Ahmed Almheiri, Tarek Anous, Aitor Lewkowycz

Based on the work of Heemskerk, Marolf, Polchinski and Sully (HMPS), we study the reconstruction of operators behind causal horizons in time dependent geometries obtained by acting…

Entropy, Extremality, Euclidean Variations, and the Equations of Motion

Xi Dong, Aitor Lewkowycz

We study the Euclidean gravitational path integral computing the Renyi entropy and analyze its behavior under small variations. We argue that, in Einstein gravity, the extremality…

Bulk locality from modular flow

Thomas Faulkner, Aitor Lewkowycz

We study the reconstruction of bulk operators in the entanglement wedge in terms of low energy operators localized in the respective boundary region. To leading order in , the d…

A CFT Perspective on Gravitational Dressing and Bulk Locality

Aitor Lewkowycz, Gustavo J. Turiaci, Herman Verlinde

We revisit the construction of local bulk operators in AdS/CFT with special focus on gravitational dressing and its consequences for bulk locality. Specializing to 2+1-dimensions,…

Deriving covariant holographic entanglement

Xi Dong, Aitor Lewkowycz, Mukund Rangamani

We provide a gravitational argument in favour of the covariant holographic entanglement entropy proposal. In general time-dependent states, the proposal asserts that the entangleme…

Relative entropy equals bulk relative entropy

Daniel L. Jafferis, Aitor Lewkowycz, Juan Maldacena +1

We consider the gravity dual of the modular Hamiltonian associated to a general subregion of a boundary theory. We use it to argue that the relative entropy of nearby states is giv…

Universality in the geometric dependence of Renyi entropy

Aitor Lewkowycz, Eric Perlmutter

We derive several new results for Renyi entropy, , across generic entangling surfaces. We establish a perturbative expansion of the Renyi entropy, valid in generic quantum fie…

Renyi entropy, stationarity, and entanglement of the conformal scalar

Jeongseog Lee, Aitor Lewkowycz, Eric Perlmutter +1

We extend previous work on the perturbative expansion of the Renyi entropy, , around for a spherical entangling surface in a general CFT. Applied to conformal scalar fie…

Quantum corrections to holographic entanglement entropy

Thomas Faulkner, Aitor Lewkowycz, Juan Maldacena

We consider entanglement entropy in quantum field theories with a gravity dual. In the gravity description, the leading order contribution comes from the area of a minimal surface,…

Generalized gravitational entropy

Aitor Lewkowycz, Juan Maldacena

We consider classical Euclidean gravity solutions with a boundary. The boundary contains a non-contractible circle. These solutions can be interpreted as computing the trace of a d…
