Is there a geometric analogue to this, too; like the amplituhedron?

/? amplituhedron

From "Deflection of electromagnetic waves by pseudogravity in distorted photonic crystals" (2023) https://journals.aps.org/pra/abstract/10.1103/PhysRevA.108.0... :

> Amplituhedrons are also "quantum-geometric" "manifolds" (?); and so no Feynman diagrams.

> [...]

> "Coherent Surface Plasmon Polariton Amplification via Free Electron Pumping" (2022) https://doi.org/10.21203/rs.3.rs-1572967/v1

From https://news.ycombinator.com/item?id=30782678 :

> - [ ] Maybe Twistor theory has insight into a classical geometrical formulation that could be run on a non-QC?

> Amplituhedron: https://en.wikipedia.org/wiki/Amplituhedron

Would this electron-phonon and polaron model make a better fusion induction welding simulator?
