These phonons are circularly polarized and are thus able to carry the missing angular momentum away from the electron spins. “The angular momentum goes directly into the phonons,” Baum explains. ...

The orbital angular momentum is one of the fundamental quantum numbers of the electron, similar to spin, which describes the apparent rotation of the electron. However, OAM is rarely observable in ...

A research team succeeds in solving a decade-old physical puzzle: the question of the fate of angular momentum during the ultrafast demagnetization of nickel crystals by laser light.

The orbital angular momentum is one of the fundamental quantum numbers of the electron, similar to spin, which describes the apparent rotation of the electron. However, OAM is rarely observable in ...

The second and third quantum numbers, introduced by Sommerfeld, pertained to aspects of an electron’s angular momentum (a measure of the shape and configuration of its orbit).

The injected excess amount of angular momentum may exert mechanical torque on it. This is the idea. In this study, the researchers fabricated a micro cantilever structure made of magnetic ...

A state-of-the-art access to QED phenomena is the so-called g-factor of the electron, which describes the relation of its mechanic (intrinsic angular momentum: spin) and magnetic properties.

The orbital angular momentum is one of the fundamental quantum numbers of the electron, similar to spin, which describes the apparent rotation of the electron. However, OAM is rarely observable in ...
