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.

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 ...

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 ...

Pseudogauge freedom and the SO(3) algebra of spin operators
Physics Letters B, 2023 The energy-momentum and spin tensors for a given theory can be replaced by alternative expressions that obey the same conservation laws for the energy, linear momentum, as well as angular momentum but, however, differ by the local redistribution of such ...

Quantum field theory for spin operator of the photon
Physical Review Research, 2022 All elementary particles in nature can be classified as fermions with half-integer spin and bosons with integer spin. Within quantum electrodynamics (QED), even though the spin of the Dirac particle is well defined, there exist open questions on the ...

Spin Hall Effect of Double-Index Cylindrical Vector Beams in a Tight Focus
Micromachines, 2023 We investigate the spin angular momentum (SAM) of double-index cylindrical vector beams in tight focus. Such a set of beams is a generalization of the conventional cylindrical vector beams since the polarization order is different for the different ...

Compton effect in terms of spintronic
Results in Physics, 2016 Compton effect with spin effect is studied. Although the incoming wave has been taken into account in the current loop model the final result is the same as before.
