Correlated vortex generation in a coherent medium

We present a novel technique for transferring topological charge from an applied laser field to a newly generated field through atomic spin coherence in a ⁸⁵Rb atomic system. Utilizing a Ramsey-like configuration with two distinct interaction regions, our approach enables continuous field generation; the first region prepares coherent atomic states, while the second region facilitates the generation of the new field via coherent Raman scattering of the applied laser. We demonstrate that the generated and the applied fields exhibit a positive correlation with extended correlation times. The topological charge transfer and field generation are verified using the tilted lens detection technique, while Ramsey interferometry confirms the presence of phase-sensitive spin coherence in the second interaction region. Our method offers a promising pathway for the continuous creation of correlated fields with prolonged correlation times, having potential applications in quantum information and optical communications.
