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. The polarization of the light is commonly accepted as its “intrinsic” … See more The spin angular momentum of light (SAM) is the component of angular momentum of light that is associated with the quantum spin and the rotation between the polarization degrees of freedom of the photon. See more • Helmholtz equation • Orbital angular momentum of light • Photon polarization • Spin polarization See more General expression for the spin angular momentum is where $${\displaystyle c}$$ is the speed of light in free space and $${\displaystyle \mathbf {\pi } }$$ is the conjugate canonical momentum of the vector potential See more • Born, M. & Wolf, E.

WebSpin is one of two types of angular momentum in quantum mechanics, the other being orbital angular momentum. The orbital angular momentum operator is the quantum-mechanical counterpart to the classical angular momentum of orbital revolution and appears when there is periodic structure to its wavefunction as the angle varies.
