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

Interestingly, a "reshuffling" of angular momentum between the spin and orbital motion of the electrons could also not been detected when following the laser-induced demagnetization with a ...

An electron spin itself is a quantum spin angular momentum. Electrical transport and the manipulation of spin polarization are essential technologies if electron spins are to be employed in a device.

By changing the direction of an electron spin, angular momentum does get transferred elsewhere, like to the orbit or to another electron. Because an electron has charge, and because it’s ...

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 ...

Artist’s representation of the circular phonons. (Courtesy: Nadja Haji and Peter Baum, University Konstanz) When a magnetic material is bombarded with short pulses of laser light, it loses its ...

Ideas about angular momentum that have been borrowed from optics could allow the magnetic and spin ... Muller, D. A new spin on electron beams. Nature Nanotech 5, 764 –765 (2010 ...

A research team from Konstanz 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 electron also has an orbital angular momentum relative to the fixed atoms in the solid, which also results in a magnetic moment. The interaction between the spin and orbital moments – the famous ...
