A spinon is a quasiparticle that can arise in a solid during the spin-charge separation at temperatures close to absolute zero . The electron is split into a spinon, an orbiton and a holon . The particles can be understood as carriers of the properties of the previous electron, the spinon representing the spin quantum number of the electron, the orbiton the orbital and the holon the charge of the elementary particle . Since electrons repel each other due to their charge , they have to change their properties in order to be able to move past each other in a densely “filled” environment.

discovery

The quasiparticles Spinon and Holon were first detected experimentally in 2009 at the University of Cambridge and the University of Birmingham . It was discovered that, through quantum tunneling, electrons can “jump” from a metal surface to a tightly localized quantum wire. It is divided into two quasi-particles, the spinon and the holon.
