The SAGEX review on scattering amplitudes Chapter 14: Classical gravity from scattering amplitudes [PDF]
Journal of Physics A: Mathematical and Theoretical, 2022 Scattering amplitudes have their origin in quantum field theory, but have wide-ranging applications extending to classical physics. We review a formalism to connect certain classical observables to scattering amplitudes. An advantage of this formalism is

Conservative Binary Dynamics with a Spinning Black Hole at O(G^{3}) from Scattering Amplitudes. [PDF]
Physical Review Letters, 2022 We compute the conservative two-body Hamiltonian of a compact binary system with a spinning black hole through O(G^{3}) to all orders in velocity, including linear and quadratic spin terms.

The SAGEX review on scattering amplitudes Chapter 13: Post-Minkowskian expansion from scattering amplitudes [PDF]
Journal of Physics A: Mathematical and Theoretical, 2022 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 modern amplitude calculations in such a classical context. In this brief

The SAGEX review on scattering amplitudes Chapter 8: Half BPS correlators [PDF]
Journal of Physics A: Mathematical and Theoretical, 2022 Half BPS correlators in N=4 super Yang–Mills theory are key quantities both in the AdS/CFT correspondence as well as in scattering amplitudes research. They are dual at strong coupling to quantum gravity amplitudes.

Scattering Amplitudes, the Tail Effect, and Conservative Binary Dynamics at O(G^{4}). [PDF]
Physical Review Letters, 2021 We complete the calculation of conservative two-body scattering dynamics at fourth post-Minkowskian order, i.e., O(G^{4}) and all orders in velocity, including radiative contributions corresponding to the tail effect in general relativity. As in previous

The SAGEX review on scattering amplitudes Chapter 7: Positive geometry of scattering amplitudes [PDF]
Journal of Physics A: Mathematical and Theoretical, 2022 Scattering amplitudes are both a wonderful playground to discover novel ideas in quantum field theory and simultaneously of immense phenomenological importance to make precision predictions for e.g.

Geometry in scattering amplitudes [PDF]
Physical Review D, 2022 We formulate the field-space geometry for an effective field theory of scalars and gauge bosons. Geometric invariants such as the field-space curvature enter in both scattering amplitudes and the renormalization group equations, with the scalar and gauge
