Mapping the transverse spin sum rule in position space
Physics Letters BWe discuss in detail the relativistic spatial distribution of transverse angular momentum, including both orbital and intrinsic spin contributions. Using the quantum phase-space formalism, we begin with the definition of the three-dimensional spatial ...

Parallel axis theorem for free-space electron wavefunctions
New Journal of Physics, 2015 We consider the orbital angular momentum of a free electron vortex moving in a uniform magnetic field. We identify three contributions to this angular momentum: the canonical orbital angular momentum associated with the vortex, the angular momentum of ...

Quark angular momentum in a spectator model
Physics Letters B, 2015 We investigate the quark angular momentum in a model with the nucleon being a quark and a spectator. Both scalar and axial-vector spectators are included.

Orbital angular momentum bistability in a microlaser [PDF]
Optics Letters, 2019 Light's orbital angular momentum (OAM) is an unbounded degree of freedom emerging in helical beams that appears very advantageous technologically. Using a chiral microlaser, i.e. an integrated device that allows generating an emission carrying a net OAM, we demonstrate a regime of bistability involving two modes presenting distinct OAM (L = 0 and L = 2)

Acoustic orbital angular momentum transfer to matter by chiral scattering
New Journal of Physics, 2015 We report on orbital angular momentum exchange between sound and matter mediated by a non-dissipative chiral scattering process. An experimental demonstration is made possible by irradiating a three-dimensional printed, spiral-shaped chiral object with ...

Entanglement of polarization and orbital angular momentum [PDF]
Physical Review A, 2015 We investigate two-photon entangled states using two important degrees of freedom of the electromagnetic field, namely orbital angular momentum (OAM) and spin angular momentum. For photons propagating in the same direction we apply the idea of $\textit{entanglement duality}$ and develop schemes to do $\textit{entanglement sorting}$ based either on OAM ...

Polarization and image rotation induced by a rotating dielectric rod: an optical angular momentum interpretation [PDF]
, 2006 When light is transmitted along the axis of a rotating glass rod, the polarization of the light is rotated through a small angle [Proc. R. Soc. London, Ser. A349, 423 (1976)].
