Analysis
This paper proposes a method to map arbitrary phases onto intensity patterns of structured light using a closed-loop atomic system. The key innovation lies in the gauge-invariant loop phase, which manifests as bright-dark lobes in the Laguerre Gaussian probe beam. This approach allows for the measurement of Berry phase, a geometric phase, through fringe shifts. The potential for experimental realization using cold atoms or solid-state platforms makes this research significant for quantum optics and the study of geometric phases.
