Spin of light
WebCircularly polarized light carries spin angular momentum (SAM) of 1 ± per photon depending on the handedness, while the most general state of polarization (elliptical) is a superposition of the two. Electromagnetic fields with an azi-muthal phase dependence . exp (i φ), where is any integer, also carry orbit al angular momentum (OAM) (2 WebThe orbital angular momentum of light(OAM) is the component of angular momentum of a light beamthat is dependent on the field spatial distribution, and not on the polarization. It can be further split into an internal and an external OAM.

As the name suggests, spin was originally conceived as the rotation of a particle around some axis. While the question of whether elementary particles actually rotate is ambiguous (as they appear point-like), this picture is correct insofar as spin obeys the same mathematical laws as quantized angular momenta do; in particular, spin implies that the particle's phase changes with angle. On the other hand, spin has some peculiar properties that distinguish it from orbital angul… WebJul 12, 2024 · When light and electrons spin together. by Jenny Witt, Max Planck Institute for the Structure and Dynamics of Matter.

Spin is the fundamental property that distinguishes the two types of elementary particles: fermions with half-integer spins and bosons with integer spins. Photons, which are the quanta of light, have been long recognized as spin-1 gauge bosons.
