"information stored in THz orbital degrees of freedom prevails 100X longer than information stored in electron's spin degree of freedom... orbital angular momentum currents in tungsten travel at low speeds but reach very far... Hall-like and Rashba–Edelstein-like conversion processes based on their different dynamics... Ni good orbital angular momentum source, whereas W is a good orbital-to-charge converter... could enable ultrafast and low-dissipation data processing, a long-standing goal for future technology"
