Transfer of optical orbital angular momentum to a bound electron
The spatial structure of vortex laser beams associates angular momentum to photons, which, in addition to their spin, can be used to tailor light-matter interactions. Here, the authors excite an atomic transition with a vortex laser beam, showing that the transfer of angular momentum modifies select...

Summary: | The spatial structure of vortex laser beams associates angular momentum to photons, which, in addition to their spin, can be used to tailor light-matter interactions. Here, the authors excite an atomic transition with a vortex laser beam, showing that the transfer of angular momentum modifies selection rules. |
