Light beams with a helical phase-front possess orbital angular momentum along their direction of propagation in addition to the spin angular momentum that describes their polarisation. Until recently, ...
OAM is associated with rotation of a particle about a fixed axis. The axial particle currents are encoded in the spiral phase profile of the particle’s wavefunction. The component of OAM parallel to ...
Monopoles of orbital angular momentum (OAM) are a tantalizing prospect for orbitronics because OAM is uniform in all directions. This would mean that information flows could be generated in any ...
