Oh, they're trying to define the majorana as a collective interaction of elementary particles (quasiparticle) which is a bit less interesting. |

In 1937, after the rise of quantum mechanics, Ettore Majorana, an Italian theoretical physicist, realized that the new physics implied the existence of a novel type of particles, now called Majorana fermions. After a 75-year hunt, researchers have now spotted the first solid evidence of their existence. And their discovery could hold the key to finally creating workable quantum computers... more here |

What do you think quarks are? Quarks as Quasiparticles |

Also, what this experiment failed to do was describe any expected topological structure, |

They are composed of smaller parts! Quarks are a generalization of groups of particles that behave very similarly, and thus are categorized up, down, left, right, strange, and charm, depending on their "spin" (a quality of particles that describes behavior after a collision). The modern standard model is the closest practical explanation we have for these events, but by no means is the end-all-be-all theory of physics, save unification. |

Oh ok, I think I underestimated the definition of quasiparticles. |

I'm actually still a little confused here... Quasiparticles are defined as emergent entities that only act like elementary particles of their own (as far as I interpreted). I can understand how quarks could be seen as necessarily a part of quasiparticles, like protons and neutrons, but if they're quasiparticles themselves wouldn't this entail unknown elementary particles who's interactions create them? I thought quarks were thought to be elementary as of now, am I just thinking about this wrong? |

It entails the entire statistical framework describing intrinsic angular momentum, interaction between particles, properties of decay, and more; basically, how particles behave after a collision, or other natural event such as atmospheric phenomena. |
|
This is still ambiguous to me, are you saying that quarks can be seen as quasiparticles of their properties? |

Quarks can be seen as quasiparticles which are distinctive in their statistical descriptions based on certain know properties that are observed during their manifestation, yes. Another type of quasiparticle you might be familiar with is the phonon and its application to solid state electronics, crystallography, thermodynamics, and other subjects. Emergent phenomena are often described by their modes of vibration, oscillations, and other general mathematical behavior within microscopic physical lattice structures. Quantum mechanics is only one aspect of the usefulness of the idea of quasiparticles, but it is definitely the most complex version of the quasipartcle umbrella. |
