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 ...

Although the orbits are tight, they are still much larger than the electron orbitals in atoms—the perfect recipe for getting them to notice light carrying orbital angular momentum. The ...

The basic idea is to utilize not only an electron's charge, but also its spin and orbital moment when processing information. Spin is the intrinsic angular momentum of an electron, and the orbital ...
