On the Numerical Integration of One-Loop Cosmological Collider Signals
Michael Borinsky, Aidan Herderschee, Qianshu Lu
In a broad class of inflationary models, the leading non-Gaussian bispectrum arises from one-loop rather than tree-level processes. However, realistic one-loop contributions remain…
Gravitational Effective Theories with Maximal Supersymmetry and a Peculiar Parity
Justin Berman, Simon Caron-Huot, Aditi V. Chandra +4
We study the space of four-dimensional ultraviolet completions for supergravity that are described at low energies by weakly-coupled effective field theories (EFTs)…
Inner Horizon Saddles and a Spectral KSW Criterion
Jacqueline Caminiti, Aidan Herderschee
The Bekenstein-Hawking entropy formula receives significant corrections for charged black holes near extremality. Using standard results in JT gravity, the correction…
String Theory from Maximal Supersymmetry
Henriette Elvang, Aidan Herderschee, Roger Morales
We explore the space of non-gravitational, maximally supersymmetric, planar 4d effective field theories (EFTs) that have super Yang-Mills (SYM) at leading order. In…
Asymptotic Simplicity and Scattering in General Relativity from Quantum Field Theory
Stefano De Angelis, Aidan Herderschee, Radu Roiban +1
We investigate the fate of asymptotic simplicity in physically relevant settings of compact-object scattering. Using the stress tensor of a two-body system as a source, we compute…
Stringy algebras, stretched horizons, and quantum-connected wormholes
Aidan Herderschee, Jonah Kudler-Flam
While the supergravity limit of AdS/CFT has been extensively explored, the regime in which stringy dynamics dominate, characterized by the emergence of an infinite tower of higher-…
Bounding field excursions along null geodesics with applications to cosmology
Aidan Herderschee, Aron C. Wall
Scalar fields in theories of gravity often inhabit a moduli space of vacua, and coherent spatial or temporal variations in their expectation values can produce measurable gravitati…
Feynman-like parameterizations of (anti-)de Sitter Witten diagrams for all masses at any loop order
Aidan Herderschee
Computing correlation functions in curved spacetime is central to both theoretical and experimental efforts, from precision cosmology to quantum simulations of strongly coupled sys…
A Jammed Parisi Ansatz
Michael Winer, Aidan Herderschee
Constraint Satisfaction Problems are ubiquitous in fields ranging from the physics of solids to artificial intelligence. In many cases, such systems undergo a transition when the r…
Higher-point correlators in the BFSS matrix model
Anna Biggs, Aidan Herderschee
We investigate higher-point correlators in the BFSS matrix model, a non-conformal theory dual to type IIA string theory, using Witten diagrams and techniques from the amplitudes pr…
Failure of the large-N expansion in a Bosonic Tensor Model
Aidan Herderschee, Michael Winer
We study the tensor model generalization of the quantum -spherical model in the large- limit. While the tensor model has the same large- expansion as the disordered quantu…
Difference Equations and Integral Families for Witten Diagrams
Mark Alaverdian, Aidan Herderschee, Radu Roiban +1
We show that tree-level and one-loop Mellin space correlators in anti-de Sitter space obey certain difference equations, which are the direct analog to the differential equations f…
Gravitational Waveform: A Tale of Two Formalisms
Donato Bini, Thibault Damour, Stefano De Angelis +4
We revisit the quantum-amplitude-based derivation of the gravitational waveform emitted by the scattering of two spinless massive bodies at the third order in Newton's constant, $h…
Three Point Amplitudes in Matrix Theory
Aidan Herderschee, Juan Maldacena
We compute the three graviton amplitude in the Banks-Fischler-Shenker-Susskind matrix model for M-theory. Even though the three point amplitude is determined by super Poincare inva…
Soft Theorems in Matrix Theory
Aidan Herderschee, Juan Maldacena
We show that the Banks-Fischler-Shenker-Susskind matrix model for M-theory obeys the leading and subleading soft theorems expected from eleven-dimensional supergravity. The sublead…
Flattening of the EFT-Hedron: Supersymmetric Positivity Bounds and the Search for String Theory
Justin Berman, Henriette Elvang, Aidan Herderschee
We examine universal positivity constraints on scattering in 4d planar supersymmetric Yang-Mills theory with higher-derivative corrections. We present numerical evi…
The Sub-Leading Scattering Waveform from Amplitudes
Aidan Herderschee, Radu Roiban, Fei Teng
We compute the next-to-leading order term in the scattering waveform of uncharged black holes in classical general relativity and of half-BPS black holes in supergr…
Bootstrapping the String KLT Kernel
Alan Shih-Kuan Chen, Henriette Elvang, Aidan Herderschee
We show that a generalized version of the 4-point string theory KLT double-copy map is the most general solution to the minimal-rank double-copy bootstrap in effective field theory…
Emergence of String Monodromy in Effective Field Theory
Alan Shih-Kuan Chen, Henriette Elvang, Aidan Herderschee
String monodromy is a set of linear relations among open string tree amplitudes with different orderings of the vertex operators. In this Letter, we show how these intrinsically st…
On the Differential Representation and Color-Kinematics Duality of AdS Boundary Correlators
Aidan Herderschee, Radu Roiban, Fei Teng
The AdS boundary correlators and their dual correlation functions of boundary operators have been the main dynamic observables of the holographic duality relating a bulk AdS theory…
A New Framework for Higher Loop Witten Diagrams
Aidan Herderschee
The differential representation is a novel formalism for studying boundary correlators in -dimensional anti-de Sitter space. In this letter, we generalize the differential r…
Generalizations of the Double-Copy: the KLT Bootstrap
Huan-Hang Chi, Henriette Elvang, Aidan Herderschee +2
We formulate a new program to generalize the double-copy of tree amplitudes. The approach exploits the link between the identity element of the KLT algebra and the KLT kernel, and…
BCJ Amplitude Relations for Anti-de Sitter Boundary Correlators in Embedding Space
Pranav Diwakar, Aidan Herderschee, Radu Roiban +1
We generalize the color/kinematics duality of flat-space scattering amplitudes to the embedding space formulation of AdS boundary correlators. Kinematic numerators and propagators…
Algebraic branch points at all loop orders from positive kinematics and wall crossing
Aidan Herderschee
There is a remarkable connection between the boundary structure of the positive kinematic region and branch points of integrated amplitudes in planar SYM. A long st…
