Tom S. Seifert and colleagues published their latest work on ultrafast orbital currents in the journal “Nature Nanotechnology”. Using terahertz-emission spectroscopy, the researchers found strong evidence for optically triggered orbital angular momentum currents in Ni|W thin-film stacks. Surprisingly, those currents seem to travel for 10s of nm without undergoing any scattering.
