Out-of-time-order asymptotic observables are quasi-isomorphic to time-ordered amplitudes
Abstract Asymptotic observables in quantum field theory beyond the familiar S-matrix have recently attracted much interest, for instance in the context of gravity waveforms. Such observables can be understood in terms of Schwinger-Keldysh-type ‘amplitudes’ computed by a set of modified Feynman rules...
