From the Gravitational Compton Amplitude to Black Hole Perturbation Theory
N. Emil J. Bjerrum-Bohr, Gang Chen, Carl Jordan Eriksen +1
We employ a single worldline effective field theory in a Schwarzschild-Tangherlini background to compute the gravitational Compton amplitude up to third post-Minkowskian order. Aft…
The gravitational Compton amplitude from flat and curved spacetimes at second post-Minkowskian order
N. Emil J. Bjerrum-Bohr, Gang Chen, Carl Jordan Eriksen +1
We utilize various computational techniques in flat and curved backgrounds to calculate the classical gravitational Compton amplitude up to the second post-Minkowskian order. Our n…
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…
Generalized Symmetry in Dynamical Gravity
Clifford Cheung, Maria Derda, Joon-Hwi Kim +3
We explore generalized symmetry in the context of nonlinear dynamical gravity. Our basic strategy is to transcribe known results from Yang-Mills theory directly to gravity via the…
Effective Field Theory for Extreme Mass Ratios
Clifford Cheung, Julio Parra-Martinez, Ira Z. Rothstein +2
We derive an effective field theory describing a pair of gravitationally interacting point particles in an expansion in their mass ratio, also known as the self-force (SF) expansio…
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…
Mining the Geodesic Equation for Scattering Data
Clifford Cheung, Nabha Shah, Mikhail P. Solon
The geodesic equation encodes test-particle dynamics at arbitrary gravitational coupling, hence retaining all orders in the post-Minkowskian (PM) expansion. Here we explore what ge…
Deriving spin-1 quartic interaction vertices from closure of the Poincaré algebra
Sudarshan Ananth, Aditya Kar, Sucheta Majumdar +1
We derive the quartic interaction vertex of pure Yang-Mills theory by demanding closure of the light-cone Poincaré algebra in four-dimensional Minkowski spacetime. This calculation…
Gravitation and quadratic forms
Sudarshan Ananth, Lars Brink, Sucheta Majumdar +2
The light-cone Hamiltonians describing both pure Yang-Mills and N=4 super Yang-Mills may be expressed as quadratic forms. Here, we show that this feature extends to theories of gra…
