Twisted-Light-Ion Interaction: The Role of Longitudinal Fields
The propagation of light beams is well described using the paraxial approximation, where field components along the propagation direction are usually neglected. For strongly inhomogeneous or shaped light fields, however, this approximation may fail, leading to intriguing variations of the light-matt...

The propagation of light beams is well described using the paraxial approximation, where field components along the propagation direction are usually neglected.
