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

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 ...

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, ... ). If L is the electron's orbital angular ...

Here we excite an atomic transition with a vortex laser beam and demonstrate the transfer of optical orbital angular momentum to the valence electron of a single trapped ion. We observe strongly ...

Angular momentum does not necessarily need to involve ... the demagnetization of nickel crystals using ultrafast electron diffraction—a highly precise measuring method in terms of time and ...

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 – ...

physicists interpreted the finding as meaning that the electron carried with it some intrinsic angular momentum, as if it were spinning, even though it couldn't be. Nevertheless, the idea was ...

and hence with the electron's spin angular momentum. Now a spin-orbit coupling that had previously been neglected is found to possibly be strong enough to give rise to an unconventional type of ...
