Interplay between optical vortices and condensed matter

GF Quinteiro Rosen, PI Tamborenea, T Kuhn - Reviews of Modern Physics, 2022 - APS
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 …

Photoelectric effect with a twist

G De Ninno, J Wätzel, PR Ribič, E Allaria, M Coreno… - Nature …, 2020 - nature.com
Photons have fixed spin and unbounded orbital angular momentum (OAM). While the former
is manifested in the polarization of light, the latter corresponds to the spatial phase …

Angular momentum transfer in interaction of Laguerre-Gaussian beams with atoms and molecules

PK Mondal, B Deb, S Majumder - Physical Review A, 2014 - APS
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 …

Enhancement of persistent currents and magnetic fields in a two dimensional quantum ring

V Prasad, M Arora, Varsha - Scientific Reports, 2023 - nature.com
We present the study of the SiGe quantum ring (QR) modeled by an anharmonic axially
symmetric potential with a centrifugal core in the effective mass approximation. We show …

Interaction of twisted light with a trapped atom: Interplay between electronic and motional degrees of freedom

Formulation of the twisted-light–matter interaction at the phase singularity: The twisted-light gauge

GF Quinteiro, DE Reiter, T Kuhn - Physical Review A, 2015 - APS
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 …
