Emergent causality and the N-photon scattering matrix in waveguide QED

Emergent causality and the N-photon scattering matrix in waveguide QED

In this work we discuss the emergence of approximate causality in a general setup from waveguide QED—i.e. a one-dimensional propagating field interacting with a scatterer. We prove that this emergent causality translates into a structure for the N -photon scattering matrix. Our work builds on the de...
