While using X-rays from the Swiss Light Source (SLS) fired at Sr2CuO3, physicists at the Paul Scherrer Institute observed an electron splitting into two new particles, the spinon and the orbiton.

Results may help to understand high-temperature superconductivity
Observation of the electron splitting apart may also have important implications for another current research field – that of high-temperature superconductivity. Due to the similarities in the behaviour of electrons in Sr2CuO3 and in copper-based superconductors, understanding the way electrons decay into other types of particles in these systems might offer new pathways towards improving our theoretical understanding of high-temperature superconductivity.
