Research on spatially structured light has seen an explosion in activity over the past
decades, powered by technological advances for generating such light and driven by …

Any coherent interaction of light and atoms needs to conserve energy, linear momentum and
angular momentum. What happens to an atom's angular momentum if it encounters light that …

We propose and analyze an efficient scheme for the coherent transfer of optical vortices in a
cold atomic ensemble with four-level double-Λ configuration. The orbital angular-momentum …

We describe and demonstrate how 3D magnetic field alignment can be inferred from single
absorption images of an atomic cloud. While optically pumped magnetometers …

We investigate the interaction of laser pulses carrying orbital angular momentum (OAM) with
a symmetry-broken ladder-type quantum coupling scheme involving three internal states. A …

Quantum memories that are capable of storing multiple spatial modes offer advantages in
speed and robustness when incorporated into quantum networks. When it comes to spatial …

We propose a scheme to demonstrate spatiotemporal-vortex four-wave mixing (FWM) in an
asymmetric semiconductor double quantum-well nanostructure. It is found that the orbital …

Recently a scheme has been proposed for detection of the structured light by measuring the
transmission of a vortex beam through a cloud of cold rubidium atoms with energy levels of …

We consider interaction of a pair of counterpropagating spatially inhomogeneous weak
vortex beams with a quantum emitter that has a double-V level scheme and closely situated …

We propose a scheme to demonstrate the manipulation of space-dependent four-wave
mixing (FWM) in a four-level atomic system. By adjusting the detuning of the control field …
