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

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.

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 ...

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 ...

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 ...

Angular momentum is a property of rotating bodies, which is a conserved quantity in fundamental physics. Elementary particles like the electron have intrinsic angular momentum, which we label "spin." ...

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 ...

It is well known in optics that photons carry angular momentum of ± when circularly polarized. This is called spin angular momentum and was demonstrated experimentally by Beth 8 in 1935. Linearly ...

Electrons, however, possess a well defined “spin” angular momentum, in addition to a well defined charge. Their spin is either +1/2 or -1/2: in other words an electron can rotate either clockwise or ...

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 ...
