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 ...

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 ...

Central to recent advances is the manipulation of the electron’s orbital angular momentum (OAM), which arises from a helical phase structure in the electron’s wave function.

The orbital angular momentum of electrons has long been considered a minor physical phenomenon, suppressed in most crystals and largely overlooked. Scientists at Forschungszentrum Jülich have now ...

Just after demagnetization, collective lattice vibrations, or phonons, appear. These phonons are circularly polarized and are thus able to carry the missing angular momentum away from the electron ...

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 ...

Bohr suggested that the electron's angular momentum should be quantized, that is, it could only have certain values, set by the integers (n = 1, 2, 3, ...

The team, headed by Professor Jun Yuan and Professor Mohamed Babiker, from the University’s Department of Physics has created electron beams with orbital angular momentum – electron vortex beams – ...
