Interest in the multiple facets of optical vortices has flourished in the last three decades. This
review examines the basic research and applications of the interplay between optical …

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

Twisted light is light carrying orbital angular momentum. The profile of such a beam is a
ringlike structure with a node at the beam axis, where a phase singularity exists. Due to the …

A method to efficiently evaluate integrals containing the product of three Bessel functions of
the first kind and of any non negative real order is presented. The numerical problem is …

The formulation of the interaction of matter with singular light fields needs special care. In a
recent article [GF Quinteiro, Phys. Rev. A 91, 033808 (2015) PLRAAN 1050-2947 …

Fueled by the rapid pace of technological advancements, the convergence of ideas from
optics and solid-state physics is yielding valuable insights into the fundamental principles …

An optical vortex is an inhomogeneous light beam having a phase singularity at its axis,
where the intensity of the electric and/or magnetic field may vanish. Already well studied are …

We introduce pump-probe magneto-orbital spectroscopy, wherein Laguerre-Gauss optical
pump pulses impart orbital angular momentum to the electronic states of a material and …

Experimental evidence and theory on the head-on excitation of atoms by paraxial Laguerre–
Gaussian beams revealed that the longitudinal component of the field has to be taken into …

In this study, we aim to investigate the possibility of the manipulation of an aromatic ring
current and magnetic moment induced by spin angular momentum (SAM) and orbital …
