Spintronics are devices that operate leveraging the spin, an intrinsic form of angular momentum, of electrons. The ability to ...

In an introductory physics course, there are three big ideas. There is the work-energy principle, the momentum principle and then the angular momentum principle. I'll skip the work-energy principle ...

Photons can have half-integer values of angular momentum when they are confined to fewer than three dimensions. That is the conclusion of physicists in Ireland, who have revived an experiment first ...

Many people don't know too much about angular momentum—and that's fine. But what about figure skaters? Whether they understand the concept of angular momentum doesn't matter but they use it in one of ...

When a magnetic material is bombarded with short pulses of laser light, it loses its magnetism within femtoseconds (10 –15 seconds). The spin, or angular momentum, of the electrons in the material ...

Introduction You might have seen figure skaters spinning around quickly and then tucking their arms to spin faster—or opening them to spin more slowly. This happens, thanks to a physics concept known ...

Speedy Spinning Spheres! Using spheres, cylinders, and straws, the Crew and Dr. Rob learn about inertia, velocity, and conservation of energy due to angular momentum. STEM Challenge: Angular Momentum ...

Orbital angular momentum (OAM) presents a promising degree of freedom for enhancing data transmission in optical communications. By utilising the helical phase front of light beams, OAM offers a ...
