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…
