Abstract: This paper analyzes the algebraic and physical properties of the spin and orbital angular momenta of light in the quantum mechanical framework. The consequences of the fact that these are not angular momenta in the quantum mechanical sense are worked out in mathematical detail. It turns out that the spin part of the angular momentum has continuous eigenvalues. Particular attention is given to the paraxial limit, and to the definition of Laguerre--Gaussian modes for photons as well as classical light fields taking full account of the polarization degree of freedom.

Trapped atoms in spatially-structured vector light fields [32.97208255533144]
We present a framework for computing atomic transition matrix elements for light fields of arbitrary spatial mode and polarization structures. We calculate the spatial dependence of electronic and motional matrix elements for tightly focused Hermite-Gaussian, Laguerre-Gaussian and for radially and azimuthally polarized beams. We show that near the diffraction limit, all these beams exhibit longitudinal fields and field gradients, which strongly affect the selection rules and could be used to tailor the light-matter interaction.

Representation Theory and Topology of Coherent Photons with Angular Momentum [0.0]
Photons have spin and orbital angular momentum as internal degrees of freedom. Stokes parameters are spin expectation values of coherent photons. We have applied an SU(N) representation theory to describe both spin and orbital angular momentum of photons.

Spin and Orbital Angular Momentum of Coherent Photons in a Waveguide [0.0]
We show that spin and orbital angular momentum of a photon cannot be split from the total orbital angular momentum in a gauge-invariant way. By applying a standard quantum field theory using a coherent state, we obtained the gauge-independent expressions of spin and orbital angular momentum operators.

A theory of twisted (and other structured) paraxial electrons in a uniform magnetic field is developed. The observable effect of a different behavior of relativistic Laguerre-Gauss beams with opposite directions of the orbital angular momentum penetrating from the free space into a magnetic field is predicted.

The position and spin operators in the Foldy-Wouthuysen representation are quantum-mechanical counterparts of the classical position and spin variables. The spin-orbit interaction does not exist for a free particle if the conventional operators of the orbital angular momentum and the rest-frame spin are used.

Entanglement robustness to excitonic spin precession in a quantum dot [43.55994393060723]
A semiconductor quantum dot (QD) is an attractive resource to generate polarization-entangled photon pairs. We study the excitonic spin precession (flip-flop) in a family of QDs with different excitonic fine-structure splitting (FSS) Our results reveal that coherent processes leave the time post-selected entanglement of QDs unaffected while changing the eigenstates of the system.
