Role of Radial Charges on the Angular Momentum of Electromagnetic Fields: Spin- 3/2 Light
Physical Review Letters, 2018 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.

Spin and orbital angular momentum
Europhysics Letters (EPL), 2004 It is shown that the existence of a charge-neutral, idealized smooth mesoscopic rigid sphere, characterized by eleven properties, implies a relation between spin and orbital angular momentum.

Photonic quasicrystal of spin angular momentum. [PDF]
Sci AdvQuasicrystals, characterized by long-range order without translational symmetry, have catalyzed transformative advances in various fields, including optics in terms of field quasicrystals. To our knowledge, we present the first demonstration of photonic quasicrystals formed by spin angular momentum, unveiling previously unidentified spin-orbit coupling

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 ...

A decomposition of light's spin angular momentum density. [PDF]
Light Sci ApplAbstractLight carries intrinsic spin angular momentum (SAM) when the electric or magnetic field vector rotates over time. A familiar vector equation calculates the direction of light’s SAM density using the right-hand rule with reference to the electric and magnetic polarisation ellipses.

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.
