Holon (physics)

from Wikipedia, the free encyclopedia

Holons (also known as chargons) are, along with spinons and orbitons, one of three quasiparticles into which electrons in solids can split during spin-charge separation if they are enclosed extremely densely at temperatures close to absolute zero . The electron can theoretically always be viewed as the bound state of the three, with the spinon carrying the spin , the orbiton carrying the orbital location and the holon carrying the charge of the electron, but under certain conditions they can be separated and behave like independent particles.

Overview

Electrons are fermions and repel each other due to the Pauli principle . As a result, they change their behavior in regions of high electron density. Research published in July 2009 by the University of Cambridge and the University of Birmingham in England showed that electrons can flow past each other through quantum tunneling, splitting into two quasiparticles, which researchers call spinons and holons.
