Twisted light: self-torque could be used to manipulate molecules. (Courtesy: iStock/VikaSuh) Physicists in Spain and the US have shown that the orbital angular momentum, or twistedness, of light can ...

The generation of oscillations in the microwave frequency range is one of the most important applications expected from spintronics devices exploiting the spin-transfer phenomenon, which is the ...

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 ...
