A Note on a High-Energy Limit of Gravitational Perturbation Theory
Poul H. Damgaard, Ludovic Plante
The post-Minkowskian expansion of general relativity expands the metric in Newton's constant G around flat space-time, but much effort currently focuses on ways to extend its range…
Classical Observables from the Exponential Representation of the Gravitational S-Matrix
Poul H. Damgaard, Elias Roos Hansen, Ludovic Planté +1
By combining the KMOC-formalism with the exponential representation of the scattering matrix we show that the two-body scattering angle is given by the corresponding matrix element…
The Relation Between KMOC and Worldline Formalisms for Classical Gravity
Poul H. Damgaard, Elias Roos Hansen, Ludovic Planté +1
We demonstrate the equivalence between KMOC and worldline formalisms for classical general relativity, highlighting how the Keldysh-Schwinger in-in formalism is contained in both o…
Effective Field Theory and Applications: Weak Field Observables from Scattering Amplitudes in Quantum Field Theory
N. Emil J. Bjerrum-Bohr, Ludovic Planté, Pierre Vanhove
In this chapter, we will review the field-theoretic treatment of General Relativity based on an effective field theory extension of the Einstein-Hilbert action. This pragmatic rout…
Classical Gravity from Loop Amplitudes
N. Emil J. Bjerrum-Bohr, Poul H. Damgaard, Ludovic Planté +1
We describe an efficient method for extracting the parts of -dimensional loop integrals that are needed to derive observables in classical general relativity from scattering amp…
The Equivalence Principle in a Quantum World
N. E. J. Bjerrum-Bohr, John F. Donoghue, Basem Kamal El-Menoufi +3
We show how modern methods can be applied to quantum gravity at low energy. We test how quantum corrections challenge the classical framework behind the Equivalence Principle, for…
Bending of Light in Quantum Gravity
N. E. J. Bjerrum-Bohr, John F. Donoghue, Barry R. Holstein +2
We consider the scattering of lightlike matter in the presence of a heavy scalar object (such as the Sun or a Schwarzschild black hole). By treating general relativity as an effect…
Graviton-Photon Scattering
N. E. J. Bjerrum-Bohr, Barry R. Holstein, Ludovic Planté +1
We use the feature that the gravitational Compton scattering amplitude factorizes in terms of Abelian QED amplitudes to evaluate various gravitational Compton processes. We examine…
