Electron spin and orbits in carbon nanotubes are coupled

In a carbon nanotube, electrons can orbit around the tube either clockwise or counterclockwise. Conventional wisdom has been that the spin property of the electron would be the same either way, but Cornell research has shown otherwise. Credit: Cornell University
