Optical rotatum” is the term researchers coined to describe a newly discovered structure of light. Beams of light that can be shaped into corkscrew-like forms, known as optical vortices, are used ...

Light doesn’t just travel in straight lines—it can also twist. And when it does, it opens new frontiers in science and ...

A similar interference effect also appears in a closely related property of light known as orbital angular momentum, which ...

In this module we will introduce the course on the theory of angular momentum and then introduce the quantum mechanical definition of orbital momentum. We will then use the spherical harmonics to ...
