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 ...

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 ...

Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it encompasses both the intrinsic spin of particles and their orbital motion ...

Desirable among these textures, is a spherical collection of orbital angular momentums, with axis pointing to the centre, dubbed the orbital angular momentum monopole. These could exist in two states, ...

Recently, National Science Review published online the research results on three-dimensionally oriented orbital angular momentum of light from Professor Qiwen Zhan's team at the University of ...

Orbital angular momentum rotates a light beam’s wavefront around its propagation axis, giving it a corkscrew shape. Individually, the two types of angular momentum come in multiples of the reduced ...

The proposed diffractive deep neural network employs orbital angular momentum encoding and diffractive layers to process spatial information from handwritten digits, offering a robust and ...
