Spin means, in a classical picture, that the electron spins around much like a little sphere, and angular momentum describes the motion of the electron around the nucleus.

Technical Terms Orbital Angular Momentum (OAM): The quantised component of angular momentum arising from the spatial distribution and helical phase structure of an electron beam.

Orbital angular momentum monopoles, a breakthrough discovery in chiral materials by researchers at the Max Planck Institute in Halle, could revolutionize future information technology.

One possibility is spintronics, which uses the electron’s spin rather than its charge, but more recently another alternative has emerged that could be even more promising. Known as orbitronics, it ...

An experiment shows, for the first time, that a wave property of neutrons, Orbital Angular Momentum, can be controlled.

In a paper published in National Science Review, the accurate control of the three-dimensional orientation of photonic orbital angular momentum is realized based on the collision between ...

Enter orbital angular momentum: use the same wavelength, but ensure each wavelength channel carries multiple data streams, each encoded in different orbital angular momentum states.
