Motivated by conceptual problems in quantum theories of gravity, the gravitational eikonal
approach, inspired by its electromagnetic predecessor, has been successfully applied to the …

The post-Minkowskian expansion of Einstein's general theory of relativity has received much
attention in recent years due to the possibility of harnessing the computational power of …

We obtain the total impulse in the scattering of nonspinning binaries in general relativity at
fourth post-Minkowskian order, ie, O (G 4), including linear, nonlinear, and hereditary …

Using the N= 1 supersymmetric, spinning worldline quantum field theory formalism, we
compute the conservative spin-orbit part of the momentum impulse Δ pi μ, spin kick Δ S i μ …

Using the spinning worldline quantum field theory formalism we calculate the quadratic-in-
spin momentum impulse Δ pi μ and spin kick Δ ai μ from a scattering of two arbitrarily …

We compute the radiation reacted momentum impulse Δ pi μ, spin kick Δ S i μ, and
scattering angle θ between two scattered spinning massive bodies (black holes or neutron …

A bstract 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 …

A bstract We exhibit an initial-value formulation of the worldline quantum field theory (WQFT)
approach to the classical two-body problem in general relativity. We show that the …

We review recent progress and future prospects for harnessing powerful tools from
theoretical high-energy physics, such as scattering amplitudes and effective field theory, to …

We use a previously developed scattering-amplitudes-based framework for determining two-
body Hamiltonians for generic binary systems with arbitrary spin S. By construction this …
