Holon (physics)

In physics, a "holon" refers to a quasiparticle that represents a charged particle in an electronic system. The concept of a holon arises in the context of one-dimensional systems and particularly in models that describe strong correlations, such as the Hubbard model and the study of spin-charge separation in strongly correlated electron systems. The idea of spin-charge separation suggests that in certain one-dimensional materials, the charge and spin of an electron can behave independently.
