| May 29, 2023 at 7:46 | comment | added | Martin C. | @Obama2020 I could provide an explicit construction for two interacting scalar fields in (1+1) dimensions that relies on a perturbative expansion around a topological soliton solution. Would that be interesting or helpful to you? It might not give much insight into the 'general' case, but shows how one can construct such things. | |
| May 27, 2023 at 16:15 | comment | added | FlatterMann | In a homogeneous spacetime with interactions asymptotic states don't even exist. No matter how weak an interaction, the physical vacuum would always look completely opaque as we take the limit to infinity. It's just not a physically meaningful scenario. | |

| May 24, 2023 at 11:19 | comment | added | Prahar | The real right answer is that this is an axiom in $S$-matrix theory so we have no need to justify it (other than the requirement that it is consistent with other axioms). There are QFTs which violate this (e.g., QCD) and other techniques are often needed to study scattering processes in this case. | |
