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 …

We review the topic of quantized vortices in multicomponent Bose–Einstein condensates of
dilute atomic gases, with an emphasis on the two-component condensates. First, we review …

We investigate the performance of a symmetrical two-dimensional electromagnetically
induced grating produced in a four-level N-type atomic scheme, which interacts with a weak …

We demonstrate the coherent transfer of the orbital angular momentum of a photon to an
atom in quantized units of ℏ, using a 2-photon stimulated Raman process with Laguerre …

We show how strong light-mediated resonant dipole-dipole interactions between atoms can
be utilized in a control and storage of light. The method is based on a high-fidelity …

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 propose a theoretical scheme for creating a two-dimensional Electromagnetically
Induced Grating in a three-level Λ-type atomic system interacting with a weak probe field …

Optical vortices generically arise when optical beams are combined. Recently, we reported
how several laser beams containing optical vortices could be combined to form optical …

Structured light, particularly in the terahertz frequency range, holds considerable potential
for a diverse range of applications. However, the generation and control of structured …

We conduct theoretical and numerical studies of the performance of a 2D
electromagnetically induced grating in a 4-level quantum system, which is situated near a …
