Orbital angular momentum has the potential to transfer, manipulate and store information. They are made from the orbital angular momentum of electrons orbiting their atomic nucleus – and the study of ...

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 ...

The orbital angular momentum (OAM) of electromagnetic waves — a kind of “structured light” — is associated with a helical or twisted wavefront. The helical modes are characterized by a topological ...

Optical holography is a powerful method for recording and reconstructing complete optical field information, including intensity and phase. It has found extensive applications in various fields, such ...

This course introduces the quantum mechanical concept of angular momentum operator and its relationship with rotation operator. It then presents the angular momentum operators, their eigenvalues and ...
