It's not word salad. It's perfectly intelligible.

>plasmon
>stable electron oscillations in a metal-dielectric interface

>magnon
>quasiparticle representing the quanta of spin waves

>magnon-plasmon polariton
>a mode produced by the coupling of the two

>hopfion
>a 3D topological soliton similar to a 2D skyrmion

>a given Chern number in the 4D Hyparxis has a corresponding Berry phase in 3D

This is all fairly standard condensed matter physics and topology stuff.
