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

Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it ...

Electron waves that carry orbital angular momentum (OAM) are characterized by a quantized and unbounded magnetic dipole moment parallel to their propagation direction. When interacting with ...

Thanks to new ultrafast electron diffraction experiments, researchers at the University of Konstanz in Germany have now found that this “lost” angular momentum is in fact transferred from the ...

The angular momentum can be in a different direction than the angular velocity - but in this case, I is not a scalar quantity. Here is the short scoop on the angular momentum principle.

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.

Overlooked electron property opens up new avenues for orbitronics. The orbital angular momentum of electrons has long been considered a minor physical phenomenon, suppressed in most crystals and ...

Now for angular momentum. The angular momentum is a quantity that we can calculate for rotating object. It's the product of the angular velocity (how fast it spins—represented with the symbol ω ...
