Vortex states of photons, electrons, and other particles are non-plane-wave solutions of the
corresponding wave equation with helicoidal wave fronts. These states possess an intrinsic …

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 …

Traditional photonuclear reactions primarily excite giant dipole resonances, making the
measurement of isovector giant resonances with higher multipolarities a great challenge. In …

There is increasing interest in the study of chiral degrees of freedom occurring in matter and
in electromagnetic fields. Opportunities in quantum sciences will likely exploit two main …

Abstract The Gamma Factory initiative proposes to develop novel research tools at CERN by
producing, accelerating, and storing highly relativistic, partially stripped ion beams in the …

We study the coherent excitation of the S 1/2 2→ F 7/2 2 electric octupole (E 3) transition by
twisted light modes with a single Yb+ 171 ion in the dark center of a vortex beam. The …

Optical vortices are beams of laser light with screw symmetry in their wavefront. With a
corresponding azimuthal dependence in optical phase, they convey orbital angular …

Spatially-structured laser beams, eventually carrying orbital angular momentum, affect
electronic transitions of atoms and their motional states in a complex way. We present a …

The microscopic mechanism of the light-matter interactions that induce orbital angular
momentum (OAM) in electromagnetic fields is not thoroughly understood. In this work, we …

The semiclassical general formula for the probability of radiation of twisted photons by
ultrarelativistic scalar and Dirac particles moving in the electromagnetic field of a general …
