Orbital angular momentum of spin electromagnetic wave
Results in PhysicsSpin angular momentum (SAM) and Orbital angular momentum (OAM) are two distinct forms of electromagnetic angular momentum (AM). Generally, circularly-polarized (CP) wave is deemed as the typical form of spin wave, which carries SAM only.

The angular momentum of vectorial non-paraxial fields and the role of radial charges in orbit-spin coupling [PDF]
EPJ Web of Conferences, 2020 Electromagnetic fields carry a linear and an angular momentum, the first being responsible for the existence of the radiation pressure and the second for the transfer of torque from electromagnetic radiation to matter.

Large-uncertainty intelligent states for angular momentum and angle [PDF]
, 2005 The equality in the uncertainty principle for linear momentum and position is obtained for states which also minimize the uncertainty product. However, in the uncertainty relation for angular momentum and angular position both sides of the inequality are

Spin current driven by ultrafast magnetization of FeRh
Nature Communications, 2023 Laser-induced ultrafast demagnetization is an important phenomenon that probes arguably the ultimate limits of the angular momentum dynamics in solid. Unfortunately, many aspects of the dynamics remain unclear except that the demagnetization transfers ...

On the dragging of light by a rotating medium [PDF]
, 2007 When light is passing through a rotating medium the optical polarization is rotated. Recently, it has been reasoned that this rotation applies also to the transmitted image.

Rotation of electromagnetic fields and the nature of optical angular momentum [PDF]
, 2010 The association of spin and orbital angular momenta of light with its polarization and helical phase fronts is now well established. The problems in linking this with electromagnetic theory, as expressed in Maxwell's equations, are rather less well known.

Spin angular momentum of Gaussian beams with several polarization singularities
Компьютерная оптика, 2023 We study a paraxial vector Gaussian beam with several polarization singularities located on a circle. Such a beam is superposition of a cylindrically polarized Laguerre-Gaussian beam and a linearly polarized Gaussian beam.

Conversion of a beam carrying fractionnal angular momentum in High-Harmonics Generation [PDF]
EPJ Web of Conferences, 2023 Exotic light fields combining non-trivial spin and angular momentum may not be eigenstates of either the spin or orbital angular momenta operators. For these fields, it is relevant to define a Generalized Angular Momentum operator of which they are ...
