Fundamental particle ‘splits’ into quasiparticles, including the new ‘orbiton’. 
Flux Divergence Method of Solving Einstein Equations
Trying to solve Einstein Equation with new integral of motion (conserved quantity) for system. The integrals of motion are important. Let us say, that discovery of new one means the Nobel Prize.Expand


Spin–orbital separation in the quasi-one-dimensional Mott insulator Sr2CuO3
The separation of the orbital degree of freedom (orbiton) is observed using resonant inelastic X-ray scattering on the one-dimensional Mott insulator Sr2CuO3 to resolve an orbiton separating itself from spinons and propagating through the lattice as a distinct quasi-particle with a substantial dispersion in energy over momentum.

Observation of Spin-Charge Separation in One-Dimensional SrCuO2.
Angle-resolved photoemission data from one-dimensional SrCuO{sub 2} compounds are found to be qualitatively different from that of two- dimensional Sr{ sub 2}CuO}, and the two underlying bands having approximately 1.2 and 0.3eV energy dispersion are identified. Expand
Orbital-Independent Superconducting Gaps in Iron Pnictides
An orbital-independent superconducting gap magnitude was found for the hole Fermi surfaces, which is not expected from the superconductivity associated with spin fluctuations and nesting, but it could be better explained invoking magnetism-induced interorbital pairing, orbital fluctuations, or a combination of orbital and spin fluctuations.

The Jahn-Teller effect and magnetism: transition metal compounds
The properties of magnetic insulators containing orbitally degenerate transition metal ions (Jahn-Teller ions) are discussed. The Jahn-Teller effect in these insulators causes structural phaseExpand
