Orbital angular momentum: origins, behavior and applications [PDF]
, 2011 As they travel through space, some light beams rotate. Such light beams have angular momentum. There are two particularly important ways in which a light beam can rotate: if every polarization vector rotates, the light has spin; if the phase structure ...

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 ...

Density of optical degrees of freedom : intensity, linear and angular momentum [PDF]
, 2014 For any optical system, optical eigenmodes describe solutions of Maxwells equations that are orthogonal to each other. In their simplest free space form, these modes correspond, for example, to Bessel, Laguerre-Gaussian or Hermite-Gaussian beams. However,

On the six components of optical angular momentum [PDF]
, 2011 In special relativity the angular momentum is a rank-two antisymmetric tensor with six independent components. Three of these are the familiar generators of spatial rotation, which for light have been studied at length.

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 ...

Determining the dimensionality of bipartite orbital-angular-momentum entanglement using multi-sector phase masks [PDF]
, 2012 The Shannon dimensionality of orbital-angular-momentum (OAM) entanglement produced in spontaneous parametric down-conversion can be probed by using multi-sector phase analysers [1].

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.

Generation and manipulation of laser beams carrying orbital angular momentum for classical and quantum information applications [PDF]
, 2009 Light orbital angular momentum (OAM) has been recognized as a new promising resource for classical and quantum information applications. In contrast to the spin angular momentum, the OAM is an inherently multidimensional.
