Open AccessS-matrix path integral approach to symmetries and soft theorems
We explore a formulation of the S-matrix in terms of the path integral with specified asymptotic data, as originally proposed by Arefeva, Faddeev, and Slavnov. In the tree approximation the S-matrix is equal t...

Open AccessSystematics of boundary actions in gauge theory and gravity
We undertake a general study of the boundary (or edge) modes that arise in gauge and gravitational theories defined on a space with boundary, either asymptotic or at finite distance, focusing on efficient tech...

Open AccessRefining the cutoff 3d gravity/ \( T\overline{T} \) correspondence
Pure gravity in AdS3 is a theory of boundary excitations, most simply expressed as a constrained free scalar with an improved stress tensor that is needed to match the Brown-Henneaux central charge. Excising a fi...

Open AccessAdding flavor to the Narain ensemble
We revisit the proposal that the ensemble average over free boson CFTs in two dimensions — parameterized by Narain’s moduli space — is dual to an exotic theory of gravity in three dimensions dubbed U(1) gravit...

Open AccessAnomalous dimensions from thermal AdS partition functions
We develop an efficient method for computing thermal partition functions of weakly coupled scalar fields in AdS. We consider quartic contact interactions and show how to evaluate the relevant two-loop vacuum d...

Open AccessSemi-classical Virasoro blocks: proof of exponentiation
Virasoro conformal blocks are expected to exponentiate in the limit of large central charge c and large operator dimensions hi, with the ratios hi/c held fixed. We prove this by employing the oscillator formulati...

Open AccessLight-state dominance from the conformal bootstrap
We derive forms of light-state dominance for correlators in CFTd, making precise the sense in which correlators can be approximated by the contribution of light operator exchanges. Our main result is that the fou...

Open AccessTypicality and thermality in 2d CFT
We identify typical high energy eigenstates in two-dimensional conformal field theories at finite c and establish that correlation functions of the stress tensor in such states are accurately thermal as defined b...

Open AccessRenormalization of gravitational Wilson lines
We continue the study of the Wilson line representation of conformal blocks in two-dimensional conformal field theory; these have an alternative interpretation as gravitational Wilson lines in the context of t...

Open AccessLate time Wilson lines
In the AdS3/CFT2 correspondence, physical interest attaches to understanding Virasoro conformal blocks at large central charge and in a kinematical regime of large Lorentzian time separation, t ∼ c. However, almo...

Open AccessWitten diagrams for torus conformal blocks
We give a holographic description of global conformal blocks in two dimensional conformal field theory on the sphere and on the torus. We show that the conformal blocks for one-point functions on the torus can...

Open AccessBlack holes from CFT: universality of correlators at large c
Two-dimensional conformal field theories at large central charge and with a sufficiently sparse spectrum of light states have been shown to exhibit universal thermodynamics [1]. This thermodynamics matches that o...

Open AccessA cardy formula for three-point coefficients or how the black hole got its spots
Modular covariance of torus one-point functions constrains the three point function coefficients of a two dimensional CFT. This leads to an asymptotic formula for the average value of light-heavy-heavy three p...

Open AccessHolographic conformal blocks from interacting Wilson lines
We present a simple prescription for computing conformal blocks and correlation functions holographically in AdS3 in terms of Wilson lines merging at a bulk vertex. This is shown to reproduce global conformal blo...

Open AccessGeneral results for higher spin Wilson lines and entanglement in Vasiliev theory
We develop tools for the efficient evaluation of Wilson lines in 3D higher spin gravity, and use these to compute entanglement entropy in the hs[λ] Vasiliev theory that governs the bulk side of the duality pro...

Open AccessWitten diagrams revisited: the AdS geometry of conformal blocks
We develop a new method for decomposing Witten diagrams into conformal blocks. The steps involved are elementary, requiring no explicit integration, and operate directly in position space. Central to this cons...

Open AccessSemiclassical Virasoro blocks from AdS3 gravity
