Analytical Time-Domain Waveforms for Black-Hole Scattering in the Self-Force Expansion
Chris Kavanagh, Julio Parra-Martinez, Davide Usseglio
We obtain a systematic understanding of the time-domain gravitational waveform of hyperbolic black-hole scattering at first order in the self-force expansion and all orders in the…
What Does Disagreement Mean? A Semantic Identifiability Frontier for Pairwise Preference Learning
Manoj Saravanan, Rohit Kumar Salla, Shrikar Reddy Kota
Pairwise comparison data are a standard supervision signal in preference learning, but disagreement in such data can reflect stable latent heterogeneity, ephemeral stochasticity, o…
Quantum Love Numbers are Non-Zero
Asaad Elkhidir, Godwin Martin, Julio Parra-Martinez +1
The static Love numbers of four-dimensional Schwarzschild black holes vanish classically. We show that this is not true in the quantum theory. Working in the worldline effective fi…
Gravitational Raman Scattering: a Systematic Toolkit for Tidal Effects in General Relativity
Mikhail M. Ivanov, Yue-Zhou Li, Julio Parra-Martinez +1
We present a framework for systematic computations of scattering amplitudes for gravitational Raman scattering, -- the inelastic scattering of massless fields off compact relativis…
Naturalness of vanishing black-hole tides
Julio Parra-Martinez, Alessandro Podo
We provide a symmetry argument for the vanishing and non-renormalization of static Love numbers for spherically symmetric black holes at full nonlinear order in four-dimensional Ge…
Scattering perspective on gravitational lensing
Mariana Carrillo Gonzalez, Valerio De Luca, Alice Garoffolo +2
Gravitational waves propagating across gravitational potentials undergo lensing effects that, in the wave-optics regime, manifest as frequency-dependent amplitude and phase modulat…
Generalized Unitarity Method for Worldline Field Theory
Vincent F. He, Julio Parra-Martinez
We present a generalized unitarity method for theories of point-particle worldlines coupled to gravity, analogous to that of scattering amplitudes in quantum field theory. This met…
GSO Defects: IIA/IIB Walls and the Surprisingly Stable -Brane
Jonathan J. Heckman, Jacob McNamara, Julio Parra-Martinez +1
The recently proposed Swampland Cobordism Conjecture predicts the existence of new non-supersymmetric objects which supplement the spectrum of low-energy gravitational effective fi…
Nonlinear Gravitational Memory in the Post-Minkowskian Expansion
Alessandro Georgoudis, Vasco Goncalves, Carlo Heissenberg +1
We present the first computation of the nonlinear gravitational memory waveform for the scattering of two compact objects in General Relativity at leading order in the post-Minkows…
Soft Theorems from Higher Symmetries
Jonah Berean-Dutcher, Maria Derda, Julio Parra-Martinez
We describe the connection between spontaneously-broken higher symmetries and soft theorems for scattering amplitudes of their associated Nambu-Goldstone bosons. Our main result is…
Resummation of Universal Tails in Gravitational Waveforms
Mikhail M. Ivanov, Yue-Zhou Li, Julio Parra-Martinez +1
We present a formula for the universal anomalous scaling of the multipole moments of a generic gravitating source in classical general relativity. We derive this formula in two ind…
Graviton loops and negativity
Cyuan-Han Chang, Julio Parra-Martinez
We revisit dispersive bounds on Wilson coefficients of scalar effective field theories (EFT) coupled to gravity in various spacetime dimensions, by computing the contributions from…
Classical Observables from Causal Response Functions
Shovon Biswas, Julio Parra-Martinez
We revisit the calculation of classical observables from causal response functions, following up on recent work by Caron-Huot at al. [JHEP 01 (2024) 139]. We derive a formula to co…
Gravitational Scattering and Beyond from Extreme Mass Ratio Effective Field Theory
Clifford Cheung, Julio Parra-Martinez, Ira Z. Rothstein +2
We explore a recently proposed effective field theory describing electromagnetically or gravitationally interacting massive particles in an expansion about their mass ratio, also k…

A variety of condensed matter systems describe gapless modes that can be interpreted as Nambu-Goldstone bosons of spontaneously broken Poincaré symmetry. In this paper we derive ne…
Graviton partial waves and causality in higher dimensions
Simon Caron-Huot, Yue-Zhou Li, Julio Parra-Martinez +1
Do gravitational interactions respect the basic principles of relativity and quantum mechanics? We show that any graviton S-matrix that satisfies these assumptions cannot significa…
Non-perturbative Double Copy in Flatland
Clifford Cheung, James Mangan, Julio Parra-Martinez +1
We derive a non-perturbative, Lagrangian-level formulation of the double copy in two spacetime dimensions. Our results elucidate the field theoretic underpinnings of the double cop…
Geometry-Kinematics Duality
Clifford Cheung, Andreas Helset, Julio Parra-Martinez
We propose a mapping between geometry and kinematics that implies the classical equivalence of any theory of massless bosons -- including spin and exhibiting arbitrary derivative o…
