This book deals with applications in several areas of science and technology that make use
of light which carries orbital angular momentum. In most practical scenarios, the 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 predict that the Lee-Huang-Yang effect makes it possible to create stable quantum
droplets (QDs) in binary Bose-Einstein condensates with a heterosymmetric or …

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 …

We have theoretically investigated Kelvin waves of quantized vortex lines in trapped Bose-
Einstein condensates. Counterrotating perturbation induces an elliptical instability to the …

We study superfluid dissipation due to phase slips for a Bose-Einstein condensate flowing
through a repulsive barrier inside a torus. The barrier is adiabatically raised across the …

We theoretically investigate the absorption and emission of light carrying orbital angular
momentum (twisted light) by quasi-two-dimensional (disk-shaped) quantum dots in the …

We present a numerical study of the ultrafast ionization dynamics of H 2+ exposed to
attosecond extreme ultraviolet (xuv) pulses that goes beyond the Born-Openheimer …

We obtain an expression for the matrix element for scattering of a twisted (Laguerre–
Gaussian profile) photon from a hydrogen atom. We consider photons incoming with an …

Efficient helicity transfer from Poincaré fields to electrons of hydrogenic ions is revealed for
the first time by four-dimensional relativistic simulations. The magnetic multipole class of …
