In recent years, remarkable progress has been made in the generation and detection of structured light [1], unlocking new possibilities for applications in high-capacity optical data storage and continuous variable quantum technologies. Building on these advancements, this talk explores the spatially structured light-matter interactions, with a specific focus on the interplay between optical vortices and atomic systems. The primary goal is to explore the transfer of Orbital Angular Momentum (OAM) between light and atom. This allows for the engineering of spatially dependent patterns in the absorption characteristics and population distribution of atoms. Not only does this offer insights into the fundamental nature of spatially varying light-matter interactions, enabling the creation of optical vortices of slow light [2], but it also holds the potential for the strong spatial confinement of atomic excitations [3].
