WebRussell-Saunders or L-S Coupling For multi-electron atoms where the spin-orbit coupling is weak, it can be presumed that the orbital angular momenta of the individual electrons add to form a resultant orbital angular momentum L. Likewise, the individual spin angular momenta are presumed to couple to produce a resultant spin angular momentum S. Then L and S … WebThe short answer: graphene is a counterexample. The longer version: 1) You do not need to break the time reversal symmetry. 2) spin-orbit coupling does not break the time-reversal symmetry. 3) In graphene, there are two valleys and time inversion operator acting on the state from one valley transforms it into the sate in another valley.
