Spin-orbit coupling and the conservation of angular momentum [PDF]
European Journal of Physics, 2012 In nonrelativistic quantum mechanics, the total (i.e. orbital plus spin) angular momentum of a charged particle with spin that moves in a Coulomb plus spin-orbit-coupling potential is conserved.

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.

Angular topological superfluid and topological vortex in an ultracold Fermi gas
Physical Review Research, 2022 We show that pairing in an ultracold Fermi gas under spin-orbital-angular-momentum coupling (SOAMC) can acquire topological characters encoded in the quantized angular degrees of freedom.

Spin–Orbital-Angular-Momentum Coupled Bose-Einstein Condensates [PDF]
Physical Review Letters, 2018 We demonstrate coupling between the atomic spin and orbital-angular-momentum (OAM) of the atom's center-of-mass motion in a Bose-Einstein condensate (BEC). The coupling is induced by Raman-dressing lasers with a Laguerre-Gaussian beam, and creates coreless vortices in a $F=1$ $^{87}$Rb spinor BEC.
