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 recent prediction and subsequent creation of electron vortex beams in a number of
laboratories occurred after almost 20 years had elapsed since the recognition of the physical …

Photons can carry angular momentum, not only due to their spin, but also due to their spatial
structure. This extra twist has been used, for example, to drive circular motion of microscopic …

Chirality arises universally across many different fields. Recent advancements in artificial
nanomaterials have demonstrated chiroptical responses that far exceed those found in …

The physics of optical vortices, also known as twisted light, is now a well-established and a
growing branch of optical physics with a number of important applications and significant …

We present a theoretical study of high-order harmonic generation (HHG) and propagation
driven by an infrared field carrying orbital angular momentum (OAM). Our calculations unveil …

Intense laser ionization expands Einsteins photoelectric effect rules giving a wealth of
phenomena widely studied over the last decades. In all cases, so far, photons were …

We propose a theoretical and practical framework for the study of light-matter interactions
and the angular momentum of light. Our proposal is based on helicity, total angular …

The exchange of orbital angular momentum between a Laguerre-Gaussian beam of light
and the center-of-mass motion of an atom or molecule is well known. We show that the …

We present a theoretical study of nondipole excitation of a single trapped atom by twisted
light. Special emphasis is placed on effects that arise from the interplay between internal …
