What is "spinon"

n. (context physics English) One of three kinds of quasiparticle (the others being the holon and orbiton) that electrons in solids are able to split into during the process of spin–charge separation, when extremely tightly confined at temperatures close to absolute zero.

Spinons are one of three quasiparticles, along with holons and orbitons, that electrons in solids are able to split into during the process of spin–charge separation, when extremely tightly confined at temperatures close to absolute zero. The electron can always be theoretically considered as a bound state of the three, with the spinon carrying the spin of the electron, the orbiton carrying the orbital location and the holon carrying the charge, but in certain conditions they can become deconfined and behave as independent particles.

The term spinon is frequently used in discussions of experimental facts within the framework of both quantum spin liquid and strongly correlated quantum spin liquid.
