Scientists Have Found Evidence a Strange Group of Quantum Particles Are Basically Immortal these quasiparticles <https://en.wikipedia.org/wiki/Quasiparticle> include the rotons <https://en.wikipedia.org/wiki/Roton> and the magnons <https://en.wikipedia.org/wiki/Magnon> which is a magnetic polariton.
